Many Happy Returns to the Naturalist and Broadcaster

Today, May 8th is the birthday of Sir David Attenborough, the naturalist, broadcaster and keen fossil collector who has done so much to popularise Earth sciences and a fascination with life on Earth, both extant and extinct.  We at Everything Dinosaur, would like to wish Sir David many happy returns for the day.

Happy Birthday Sir David Attenborough

Still enthusing about the natural world.

Many of our team members have been inspired by Sir David’s enthusiasm and energy.  We wanted to create a special tribute to him and as we are getting better at using the software programme Adobe CS5, we created a special banner on the Everything Dinosaur website which has been posted up today honouring the great man.  We have had the pleasure to be able to write reviews on a number of books that accompany the many television documentaries that feature Sir David.  Only the other week, we set about trying to discovery the whereabouts of the book “Life on Earth” which accompanied the 1979 seminal documentary series narrated by Sir David and made in conjunction with the BBC’s natural history unit. This book has gone missing from our office library and we have instigated a search around the offices and the warehouse to hunt down our copy.

One of the most influential television series for us, was not the “Life” series of programmes that established Sir David as the voice of natural history programming in the BBC, but a little known, short series called “Fabulous Animals” first broadcast we think in the mid 1970s.  In this programme, aimed at children, Sir David enthused about mythical creatures and the fossils that inspired the legends and myths.  For many of us, our fascination with all things Dinosauria came into being at this point.  The programme was broadcast in the summer holidays, mid-morning and although a distant memory for most of us these days, it remains a favourite amongst us.

Having covered the main Kingdoms and Phylum of the natural world, Sir David’s work stands as testament to the broadcasting qualities of the BBC’s natural history unit.  Hopefully, “Life on Earth” will be broadcast on terrestrial television once more, in the near future, giving us a chance to watch all over again an example of this extraordinary body of work which Sir David has dedicated a life time to creating.

From all of us at Everything Dinosaur – we wish Sir David Attenborough a happy birthday.

South African Crocodile Farmer Faces Cruelty Charges Against Rare Species

By |2024-04-23T14:12:35+01:00April 29th, 2012|Categories: Animal News Stories|1 Comment

South African Crocodile Farm Charged with Cruelty against Crocs.

In high demand from the fashion industry for their skins; crocodile farming has become a substantial, international business over the last three decades or so.  At Everything Dinosaur, we frequently report on crocodile attacks and encounters between the public and nuisance crocodiles that pose a threat, but our own species exploiting these ancient creatures is rarely reported upon.  However, South Africa’s national society for the prevention of cruelty to animals (SPCA) has brought criminal charges against a crocodile farm based in northern KwaZulu-Natal over the way in which crocodiles are being kept.

Crocodile Farmer

SPCA national council inspector Nazareth Appalsamy stated that charges of animal cruelty had been put upon Coen Labuschagne, who runs Metcroc Boerdery as he has allegedly contravened both the South African National Standard of Crocodiles in Captivity Act and the National Animal Protection Act.

Up to two hundred crocodiles, some of which exceed two metres in length are being kept in what has been described as “coffin-shaped” enclosures, less than two metres long, approximately 1.8 metres wide and in water only about thirty centimetres deep.  The animals are being kept in what are termed finishing pens.  To improve the saleable quality of the animal’s skin, the crocodiles are separated and put into individual pens so that other crocodiles don’t damage the hide.  The reptiles are being kept in pens that are so small, that some of the larger animals are unable to turn round or to lie out straight as their body length exceeds the length of the enclosure.

Denied shade, heating and the company of other crocodiles animal welfare officers suspect that the animals are suffering considerable distress.  Many animals are unable to leave the water that they have been provided with, the pens are just to small to house crocodiles of this size.

Commenting on the conditions, Mr Appalsamy stated:

“Some of the crocodiles themselves are more than two metres in length and so their tails are bent in the enclosure, or their heads have to be permanently at an angle.  They basically cannot lie or rest straight.  There is no shade cloth or shelter or any heating requirements, which would be necessary depending on the season.”

Crocodile Farm Visits

He went on to add that the SPCA’s action was supported by Ezemvelo KZN Wildlife which also visited the farm to inspect the conditions in which the crocodiles were being kept.  It is unfortunate, that whilst the demand for crocodile belts, shoes and handbags still exists there is the temptation to maximise profits at the expense of the animal’s welfare.

A spokesperson for Everything Dinosaur commented:

“People get very upset when they hear stories about cruelty to animals that are being kept in captivity for their fur, or when young seals are clubbed to death for their hides, but animal welfare issues extend beyond the “cute and cuddly” and it is important to ensure that other commercial industries such as crocodile farming are properly regulated to.”

SPCA inspector Mr Appalsamy said that a permit application from Labuschagne had been received about three months ago, but this was opposed, however, the organisation was alerted when another nearby crocodile farmer reported that the pens had been built.

A spokesperson for the SPCA who visited the site, said what they saw was “shocking and cruel.”

According to news sources Mr Labuschagne was in Mozambique and denied any knowledge of the criminal charges laid against him, he also denied that the conditions in which some of the crocodiles were being housed were considered cruel.

He went onto deny the measurements of the pens as given by the SPCA stating:

“That’s a lie.  It is wrong what they are saying. I don’t know where they got those measurements from.”

The case has highlighted welfare conditions for crocodiles in southern Africa and the charges will probably result in court proceedings.

Queensland Fisherman Catches Saltwater Crocodile using Prawns as Bait (A Unique Catch)

By |2024-04-23T07:34:34+01:00April 8th, 2012|Categories: Animal News Stories|0 Comments

Local Fisherman Catches 2.5-metre-long Crocodile

Queensland residents and Government officials are calling for a cull of Saltwater crocodiles as the number of close encounters with these potential man-eaters continues to increase.  One of the latest crocodile incidents took place near the town of Port Douglas (Queensland), when a local angler caught more than he bargained for when a 2.5 metre long crocodile grabbed his bait.

Twenty-nine year old school teacher, Jamie Finger was fishing at a popular spot, the old Mowbray River bridge, helping to bag himself one or two nice specimens when the crocodile grabbed the prawn that the keen angler has been using as bait.  A ten minute struggle followed as the crocodile refused to let go and Mr Fisher stubbornly held on in a bid to try to save his fishing rod.

Mr Finger, who had been fishing alone managed to get some remarkable pictures of his strange catch, before the crocodile, tired of the fishing tug of war and let the bait go, perhaps preferring to go after the barramundi, that had been Mr Finger’s original target.

When asked about his crocodilian encounter, brave Mr Finger stated that he had seen a crocodile lurking near the bridge before it disappeared under the murky brown water.  A few minutes later in a scene reminiscent from the movie “Jaws” his reel began spinning and crocodile appeared below him.

Commenting on his ordeal, Jamie said:

“At first I just thought, I’ve got a big one here, and then this croc came up and began death rolling.  At least with a shark, if you get it on land, you have some hope.  But crocs have legs.  They keep going.  I  took a few photos and a video because I thought no one would believe I had caught a croc.”

After a ten-minute fight the Saltwater crocodile let go, spitting out the bait and the hook.  Leaving Mr Finger with just a fisherman’s tale to tell.

A spokesperson from Everything Dinosaur stated:

“The Saltwater crocodile was in the area doing exactly what Mr Finger was doing – looking for some fish.  Fish tend to congregate in areas of slack water in rives such as around the supports of a bridge, the presence of prey would have attracted the crocodile to the location and the splashing a the bait hit the water would have induced this predator to attack”.

The Difference Between a Crocodile and an Alligator

There have been a number of crocodile encounters reported in the Australian media over the last few days, all involving Saltwater crocodiles.  A crocodile had to be removed from a golf course north of Cairns when it got too close to the clubhouse and a two metre long reptile attacked a car in the Mackay district.  Local ministers and officials have called for a cull of adult animals or a policy of crocodile nest destroying to try to reduce the numbers of these man-eaters in areas where people tend to go.

Local MP Warren Entsch, a former crocodile farmer stated:

“Encounters with crocodiles are increasing up here.  There is a strong argument for removal, whether it’s eggs or grown crocs out of populated areas.” 

Certainly, it is true that crocodile populations have increased rapidly since hunting and trapping was banned.  There have been further calls for culls in other areas of Queensland as well in the Northern Territories.  With Saltwater crocodiles capable of growing to lengths in excess of six metres, these formidable predators pose a series threat to locals and tourists.

Crocodile Attacks and Helpful Advice on How to Avoid Them

Saltwater Crocodiles Stalk Australian Fisherman and American Crocodile Grabs Pet

This week there have been a number of news stories about crocodiles, the majority focusing on what crocodiles do best, ambushing prey.  In Australia, a local fisherman was stalked by large Saltwater crocodiles for three days as flood waters encircled his remote fishing lodge, whilst in America a rare American crocodile attacked and killed a large, pet dog.

Unfortunately, crocodile attacks are a relatively common occurrence as tourists and fishermen venture into crocodile habitats.  The increasing number of Saltwater (Crocodylus porosus), otherwise known as Estuarine crocodiles in northern Australia has led to a number of reports of attacks by these huge, reptilian predators.

Attacks in Florida by the American crocodile (Crocodylus acutus) are much less frequent than attacks by the more common and generally thought to be the more aggressive American alligator, but for one Sunshine State couple such an attack led to the loss of their pet dog – Roxie.

The Difference Between a Crocodile and an Alligator

Crocodile and Alligator comparison.

Crocodile (top) and Alligator (bottom).

When Janet and Larry Porath and their visiting family returned to their Key Largo home from a late lunch out, they heard a splash as they relaxed in their waterfront  facing backyard.  It was the splash caused by a crocodile attack, ambushing their pet dog and dragging her into the water.

Crocodile Attack

According to the witnesses, the crocodile leaped at least four feet out of the water to snatch the 65-pound mixed breed dog head-first off the seawall.  The crocodile, estimated to be around 4 metres in length, was seen by neighbours swimming a few feet from the Poraths’ house.  Roxie was in its mouth.

The poor dog never stood a chance and after the fatal encounter the Porath’s accompanied by friends and neighbours set out to find the crocodile and to retrieve the body of their family pet.

Meanwhile, over in Australia a fisherman had a billiard table to thank for keeping him safe from a potential crocodile attack.  Sixty-five year-old Terry Donovan was relaxing at a remote fishing cabin at the Staaten River Fishing and Wilderness Lodge in northern Queensland when he became cut off by rising flood waters.

As the waters rose, he spotted a number of large crocodiles lurking in the water, one of which attacked a sheltering wallaby on the back deck of the fishing hut.

A shaken Mr Donovan said that he was afraid that the flood waters would permit one of the large four-metre-long crocs to swim into the hut and attack him.

Commenting on his three-day ordeal, Terry stated:

“The first one I saw was sitting out the back on the veranda in about a foot of water, maybe a bit more.  I thought to myself, ‘Well, there’s a warning, there’s a crocodile there.  Where there’s one, there’s probably two or three or more’.”

Donovan said a second crocodile placed itself underneath the house, after he spotted it through a window.  Becoming very concerned for his own safety Mr Donovan sort refuge on top of a billiard table, the highest place that he could find.

With some supplies packed around him, Mr Donovan watched the water level rise inch by inch.

He said:

“The water just kept going up and up and up, and it was just an inch or so above the nets where the balls are collected by the billiard table, and I thought, ‘Well, the next step is the roof, I’m out of here’.”

The plucky fisherman was rescued from his three day stand off when he was eventually spotted by a passing helicopter which had gone to check on him after he failed to answer his satellite phone.  Officials then alerted a local fishermen who set out to rescue him.  Had the water level risen any higher, Mr Donovan is certain that the crocodiles would have attacked.

Frog Blog – We have Frogspawn in the Office Pond

By |2023-02-28T10:19:32+00:00March 11th, 2012|Categories: Animal News Stories, Everything Dinosaur News and Updates|0 Comments

The Frogs have Started to Spawn

After a mild and cloudy night we have arrived this morning to discover the first batch of frogspawn in the office pond.  This was probably laid in the early hours of this morning.  So far we have counted ten frogs in the pond, all are very active and we suspect that more spawn will be laid over the next few hours or so.  We will keep a careful watch on proceedings without trying to disturb our “frog-orgy” too much.

The frogs have spawned approximately a week earlier than last year, this is perhaps due to the milder winter that we have had.  Interestingly, the spawn has been located at one of the deeper parts of the pond, according to the old wives tale, when frogs spawn in deep water it is a sign that the spring is going to be very dry – not good news for East Anglia and south-east England which are already experiencing a drought.

One of the problems of spawning in deep water is that if the frog’s activity dislodges the spawn it will roll into even deeper water and disappear towards the bottom of the pond.  If this happens the spawn may be delayed in hatching as the water temperature surrounding the spawn will be that much colder.  We suspect water temperature has a significant effect on the speed of the development of the tadpoles.

Sequencing the Estuarine Crocodile Genome

By |2023-01-26T07:59:01+00:00January 28th, 2012|Categories: Animal News Stories|0 Comments

International Team Unravels the Genome of the World’s Largest Reptile

Crocodile farm owners, palaeontologists, cladistics specialists and geneticists hope to reap the benefits of the research into Saltwater crocodile genes after a team of international scientists completed the genome sequence of this, the largest extant species of reptile.

Estuarine Crocodile Genome

The Saltwater, or Estuarine crocodile (Crocodylus porosus) is found throughout S.E. Asia, with a geographical distribution from Sri Lanka to northern Australia, this species is the mainstay of the crocodile farming industry in Asia and it is hoped that a better understanding of the genome sequence will help improve commercial crocodile breeding techniques.  In Australia alone, the crocodile industry is estimated to be worth some $8.8 million AUD in exports.

Professor Chris Moran (Sydney University’s Faculty of Veterinary Science), one of the researchers working on this genome project stated:

“We had previously completed a genome map for the Saltwater crocodile but this is a huge leap forward.  Genome sequencing is the next step.  The difference between genome mapping and genome sequencing is the difference between having a map of Australia on a single page and a detailed street directory.”

Advances in DNA sequencing technology, so-called next generation or “nextgen” sequencing, have provided between one thousand and a ten thousand-fold reduction in cost, along with comparable increases in the speed with which whole genome sequences can be generated.  The scientists estimate that a complete genome for a complex vertebrate such as a crocodile can be mapped out for a few thousand dollars, at the start of this century, to undertake such a project would have cost millions of dollars.

One of the immediate benefits to commercial crocodile farm owners is that this sequenced genome will help them to identify individual animals for breeding programmes.  Crocodiles do not become mature and able to breed until they are seven years old, which means that, currently, breeders have to wait that long before they can choose suitable breeding stock.  The genome sequencing methodology permits selection for breeding programmes at a much earlier age.  DNA samples can be taken as soon as the animals hatched and once analysed the information in the genes can be used to determine which animals will be suitable for breeding.

Professor Moran explained how the process works:

“This is possible because the genome sequence identifies genetic ‘markers’ which provide information on the likely health and breeding quality of an animal.”

Professor Moran worked on the genome sequence with his University of Sydney colleague Dr Jaime Gongora, along with PhD students Amanda Chong and Pauline Dalzell together with research affiliates Dr Sally Isberg and Dr Lee Miles.

The research team have been working on the genetics and genomics of farmed Saltwater crocodiles since 2001 with funding from the Rural Industries Research and Development Corporation.

Other outcomes of the genome sequencing work include a better understanding of the evolutionary relationships among crocodilians, especially between the alligator family and crocodile family.  It also will have implications for palaeontologists as they strive to obtain a greater  understanding of crocodilians’ relationships to other reptiles, including their closest living relatives, the birds.  The research papers were published in the scientific journal “Genome Biology”.

In unrelated research, a number of scientists have been studying the anti-bacterial properties of crocodilian blood.  An improved understanding of crocodile genomes may indirectly help speed up the development of new, anti-bacterial agents.

Exotic Pets – Victims of the Economic Downturn

By |2023-01-25T09:34:49+00:00December 16th, 2011|Categories: Animal News Stories|0 Comments

Caiman Dumped Outside Pet Shop

With the economic downturn and with a large number of people finding it hard to manage their finances many expensive to keep, exotic pets are being abandoned.  A three-foot long crocodile was dumped outside a pet shop in the West Midlands yesterday (Thursday).

Jim Wick, owner of Wickid Pets in Wolverhampton, found the South American reptile in a plastic box when he arrived at work on Thursday.  The caiman, which measures nearly a metre long and would have been quite capable of doing Mr Wick some serious damage had it chosen to, has been taken in by the exotic animal specialist, who admits he was lucky not to lose a chunk of his arm after making the discovery.

Exotic Pets

This is one of a number of recent examples of rare and exotic pets being abandoned by their thoughtless owners, perhaps after out-growing their homes or simply as a result of the owner deciding not to keep their expensive pet any more.

Jim stated:

“I thought it might have been kittens or turtles because we often have animals left outside by people who don’t want them any more.  I put my hand in straight away to test the warmth of the water.  I’m lucky it wasn’t aggressive because it could have had my hand off.”

Mr Wick recovered quickly from the surprise, and picked up the animal and took it to one of his reptile vivariums.  He hopes to be able to re-home this crocodylian, an animal more accustomed to the Amazon than Wolverhampton, at a local Safari park.

Staff at the pet shop have been looking after the female caiman, which they have named “Snappy the Christmas Crocodile”, it is possible the animal was lost and the staff are hoping that the reptile can be reclaimed, however, given how the animal was found, it is suspected that this unfortunate reptile had simply been abandoned by its former owner.  The crocodile has not been micro-chipped so it is quite probably an animal that has entered the country illegally part of the large, illicit exotic pet trade in the United Kingdom.

An Abandoned Caiman

Mr Wick said he was more than happy to keep caring for his latest visitor, which is capable of growing to a length approaching three metres.

Mr Wick has contacted the police to find out whether there have been any reports of missing crocodiles but to no avail. However, he has his own suspicions about what has happened.

“Some people aren’t given the correct facts when they buy animals like this and they find them too much to cope with.” 

Given the expense of keeping such an exotic pet it is also likely that the former owner simply could not afford to keep their pet any more.  This instance is one of a number of recent cases of exotic pets being abandoned as the economic downturn bites.  It seems that even crocodiles are not immune to the recession.

A spokesperson for Everything Dinosaur urged anyone considering the purchase of an exotic pet, perhaps as a Christmas gift to think very carefully and to take professional advice before making a such a commitment.  The spokesperson commented that crocodiles are not appropriate pets and even hatchlings are capable of injuring people.  They went onto add that any exotic pet procurement needs to be “thought through extremely carefully, as it represents a commitment of many, many years”.

Prehistoric Patagonian Squirrel-like Mammal with Sabre-Teeth Described in New Research

By |2024-04-22T13:19:32+01:00November 4th, 2011|Categories: Animal News Stories, Dinosaur and Prehistoric Animal News Stories|1 Comment

Sabre-Toothed Squirrel – Fanged Beast of the Cretaceous Night

The Cretaceous strata of southern Argentina may be associated with some of the most spectacular dinosaur fossils ever found, huge monsters such as the fearsome Mapusaurus and the herbivorous Argentinosaurus but fossils found in Patagonia have shed light on a bizarre, primitive mammal that scurried around these leviathans and shared their home.

Fossils Found in Patagonia

In a “truth is sometimes stranger than fiction”  moment, this little mammal superficially resembles “Scat” the buck-toothed, acorn chasing squirrel from the Ice Age films.  The animal has been formally named Cronopio dentiacutus.  It had extremely long teeth, a narrow snout and large eye sockets.  The large orbits in the skull (eye sockets), suggest that  it probably had a nocturnal habit or it lived in dense undergrowth, either of which would have been sensible strategies to employ as at a little over fifteen centimetres long it was about the size of a single Mapusaurus tooth.

Cronopio dentiacutus

The fossil was found in the Patagonian province of Rio Negro,  in a bed of sediment that also has produced a variety of much larger dinosaur bones.  The strata has been dated to around 93 million years ago (Cenomanian faunal stage).  The two partial skulls and jawbones bridge a sixty-million-year gap in the mammalian fossil record, according to the research paper’s authors – Sebastian Apesteguia, Leandro Gaetano and Guillermo Rougier, who describe their study in the latest edition of the scientific journal “Nature”.

Commenting on what has already been termed “a major palaeontological event”,  as this is the first mammal fossil found in Cretaceous aged rocks from the Cenomanian of South America, Christian de Muizon, (Paris Museum of Natural History) expressed excitement about the find.

De Muizon stated:

“It’s the first mammal from the Late Cretaceous period of the Mesozoic era ever found in South America.”

The scientists have classified this small creature as a member of a primitive group of mammals known as dryolestoids.  These type of mammals are believed to be ancestral to placental mammals and marsupials.  As a group, their fossil record is extremely poor with the majority of dryolestoids known from teeth and fragments of jawbone.  It is believed they had their evolutionary origins in the Middle Jurassic, surviving beyond the Mesozoic into the early Cenozoic in South America.

Named After a Book Character

Cronopio dentiacutus  was named after a type of character in the books of Argentine author Julio Cortazar.

It is likely that the long teeth at the front of the jaws helped Cronopio dentiacutus catch fast moving insects, it may superficially resemble the nut loving squirrel from the Ice Age animated movies but it is probably more closely related to marsupials like opossums than rodents.

One of the researchers (Sebastian Apesteguia – researcher at Maimonides University in Buenos Aires) stated:

“During the age of the dinosaurs, no mammal was bigger than a mouse, and they could do what they wanted, but under ground or at night — out of sight of the dinosaurs.”

It is surprising that such a statement has been made.  The size of mammals during the Mesozoic is often mis-represented in this manner.  It is indeed true that mammals were very small, especially in relation to their reptilian contemporaries during the Mesozoic but some mammals were surprisingly big, especially towards the end of the Cretaceous.  The marsupial Didelphodon, fossils of which are associated with Upper Cretaceous strata of Montana (United States) indicate an animal over a metre long – the size of a Springer Spaniel.

Christian de Muizon added:

“Such discoveries of remarkably complete Mesozoic fossils always represent giant steps” in mammalian palaeontology.  In fact, one reasonably preserved Mesozoic mammalian skull in a critical stratigraphic and geographic position can be more relevant to our understanding of mammalian evolution and bio-geography than hundreds of isolated teeth — even if teeth are the most common (and sometimes the only) remains palaeontologists work with.”

New Species of Crocodile Discovered Down a Colombian Mine

Palaeogene Crocodile Fossil Suggests Crocodiles Quick to Exploit Dinosaur Extinction

The fossilised remains of an ancient crocodile have been discovered by a team of American scientists whilst working underground exploiting a rich, fossiliferous seam in a Colombian coal mine.   This crocodile has been identified as a new species and at more than six metres long it was a sizeable reptile, one whose ancestors survived the Cretaceous mass extinction event and quickly adapted to exploit predatory niches once occupied by the Dinosauria.

Ancient Crocodile

The new species of crocodile was discovered by a team of University of Florida researchers, led by Jonathan Bloch Associate Curator of Vertebrate Palaeontology at the Florida Museum of Natural History assisted by Carlos Jaramillo, a palaeobotanist with the Smithsonian Tropical Research Institute.

This crocodile Acherontisuchus guajiraensis is just one of a number of amazing fossil discoveries made by the research team as they explore the underground strata which represent sediments laid down in a tropical Amazon-like environment approximately sixty million years ago.  A species of super-thick shelled Chelonian had been described recently, the  reason for the strong carapace being revealed with the discovery of fossils of this fearsome crocodile.

To read more about this discovery: Fossil Turtle Had Super-Thick Shell to Defend Itself from Predators.

Perhaps the most astonishing discovery made to date in the Cerrejón coal mine was the fossils of an enormous snake, the largest known in the fossil record.  The snake, a constrictor is estimated to have measured more than fifteen metres long and weighed as much as 1,200 kilogrammes.  The snake was named Titanoboa cerrejonensis it would have been an apex predator in the rain forest environment but from our research the paper’s published indicate that this snake was more closely related to Boas than to the Amazon’s largest snake – the Anaconda.

Rebor produced a limited-edition replica of Titanoboa swallowing a Columbian crocodilian.

To view the Rebor range and the Titanoboa figures (whilst stocks last): Rebor Prehistoric Figures and Replicas.

The holotype specimen for this new species was actually collected  by Alex Hastings, a University of Florida PhD student in the department of geological sciences.  The coal mine is a particularly unpleasant place to work.  The coal seams can spontaneously combust and they give off a powerful and very unpalatable sulphurous odour.  This coupled with the extreme heat and humidity makes the excavation of fossils extremely difficult.

Acherontisuchus guajiraensis

A. guaijraensis was a member of a crocodile family that were not direct ancestors of today’s crocodiles, gharials, caiman or alligators, but this discovery is important as it is helping scientists to build up a picture of ecosystems in the aftermath of the Cretaceous mass extinction event.  Judging by the size of this new crocodile species and Titanoboa it seems that sixty million years ago reptiles still ruled the world, at least in South America.

It seems that the Acherontisuchus genera survived the cataclysm that led to the dinosaurs demise and interestingly, this fossil is the first evidence of a large crocodile member of this genera being associated with a freshwater habitat.  Previously, all fossil evidence of large crocodiles ascribed to the Acherontisuchus genera had been found in association with marine environments.  This suggests that crocodiles were quick to adapt to and exploit niches vacated by other animals that did not survive the mass extinction event.

Commenting on this discovery, student Alex Hastings stated:

“One of the questions about this group was how were they able to survive – what advantages did they [Acherontisuchus genera] have?  What this new crocodile really contributes to is that it is the first evidence of a large-bodied member of this group being found in freshwater.  Before now, it was thought that only baby crocodiles would spend any appreciable amount of time in freshwater and that adults spent most of their time in a saltwater environment.”

The size estimates for this new species have been scaled up from the larger of two individual specimens discovered at the site.  Based on an analysis of the limited skull and jaw material, scientists have described this crocodile as having a long narrow snout, superficially resembling that of an extant gharial.  It seems from the shape of the jaws that this crocodile was primarily a piscivore (fish-eater).

The Cerrejón coal mine is proving to be a rich source of evidence about tropical Palaeogene environments just a few million years after the dinosaurs disappeared.  We suspect that more amazing fossils await discovery, perhaps another big crocodile, one that could even match the likes of Sarcosuchus imperator in terms of size.

Activists Demand Huge Philippine Crocodile Be Released and Set Free

By |2024-04-22T11:50:37+01:00September 10th, 2011|Categories: Animal News Stories, Main Page|0 Comments

Mayor Stands Firm Over Monster Croc

A one tonne Saltwater crocodile that was caught earlier this week, will not be released back into the wild, despite concerns for the animal’s welfare after it had not eaten since its capture.  An animal rights group urged the Philippine authorities to free what is thought to be the world’s largest crocodile in captivity, even though it allegedly killed two people.

Philippine Crocodile

The monster 6.4-metre-long male Saltwater crocodile was placed in a penned pond after it was caught in a remote southern creek on September 3rd, with local officials planning to use it as a tourist attraction once it had become adapted to its incarceration.  However, People for the Ethical Treatment of Animals senior Asia-Pacific campaigner Ashley Fruno said that despite suspicion that this reptile was a man-eater, the crocodile was better off being returned to the wild, away from human settlements.

She stated:

“The government should do the compassionate thing and order this crocodile to be returned to his natural habitat, as taking him away to be locked up in an animal prison is just plain wrong.  Penned animals are prone to psychotic behaviour and its immense size and power could prove dangerous to visitors and those caring for it.”

Expressing her concern for the creature’s welfare she added:

“While even those zoos with the best intentions can never replicate the natural environment of animals, how do they expect to come remotely close with a crocodile roughly two or three times the size of a regular adult?”

The crocodile nicknamed “Lolong” weighed 1,075 kilogrammes when it was captured earlier this week.  A number of attacks on people and livestock in the area had been reported in and around the town of Bunawan and following a programme of trapping this suspected man-eater was finally captured.  However, locals state that there are a number of very large crocodiles living in the nearby marshland.

To read more about Lolong’s capture: Monster Crocodile Captured in the Philippines.

Rollie Sumiller, who led the team that trapped the animal, commented that removing from the wild a huge reptile suspected of attacking humans was the correct thing to do.

Bunawan Mayor Edwin Elorde said that the crocodile would not be released, stating that the safety of the residents of Bunawan, Agusan del Sur remains as the top priority of the local government.
