Happy Birthday Rhoetosaurus – Australia’s First Named Dinosaur

By |2026-01-11T16:14:48+00:00January 10th, 2026|Categories: Dinosaur Fans|0 Comments

Many happy returns Rhoetosaurus on your hundredth birthday.  This unusual Australian sauropod was named and scientifically described a hundred years ago.  Rhoetosaurus (Rhoetosaurus brownei) is not that well known among the general public.  Even ardent dinosaur fans struggle to recall it.  However, this taxon is extremely important.  When described in 1926, it became Australia’s first named dinosaur.  In addition, it is the only named pre-Cretaceous sauropod known from Australia.

Its taxonomic affinity within the Sauropoda is uncertain.  For example, palaeontologist Gregory S. Paul assigns it to the Cetiosauridae family.  Size estimates also vary, body size estimates based on a partial femur and the vertebrae indicate an animal between twelve to fifteen metres in length. Other sources state that this sauropod may have grown to more than eighteen metres in length.

Rhoetosaurus brownei – Not an Elephant!

Stockmen mustering horses on a remote station, approximately thirty-five miles (fifty kilometres) north of the small town of Roma (south-western Queensland), found fossil bones weathering out of a shallow gully. They assumed that the bones were from an elephant, a pachyderm that had escaped from a circus.  Some of the vertebrae measured more than fifty centimetres long.  The station’s manager, Arthur Browne alerted Heber Longman, the director of the Queensland Museum.  Longman described Rhoetosaurus and published his work in the journal “Memoirs of the Queensland Museum (1926)”.

The fossils are thought to be around 165 million years old (Middle Jurassic).  Subsequently, a joint expedition by Queensland Museum and the University of Queensland visited the site and recovered more bones, including an almost complete right lower hind limb. Rhoetosaurus (pronounced reet-oh-sore-us) fossils probably represent a single individual.  The collection of bones collected more than fifty years apart represent one of the most complete specimens of an Australian sauropod.

A study (Nair and Salisbury) set about attempting to clarify the taxonomy. Examination of alternative phylogenetic hypotheses rules out a close relationship between Rhoetosaurus and East Asian Jurassic sauropods. The phylogeny remains unresolved.  The lower hind limb of Rhoetosaurus highlights a several anatomical traits differentiating it from other sauropods. For instance, the pes retains four claws, thought to represent a basal trait.  Most sauropods have only three claws on each hind foot.

Longman thought that Rhoetosaurus was a camarasaurid.  However, this classification has been discounted.  Whilst in the absence of further fossils, the taxonomy of Rhoetosaurus brownei remains elusive.

The CollectA Prehistoric Life Rhoetosaurus Model

In 2009, the model manufacturer CollectA introduced a Rhoetosaurus figure. It is part of their not-to-scale Age of Dinosaurs range.  The dinosaur is depicted in a rearing pose.  It is a rare model.  It measures seventeen centimetres tall.  The Rhoetosaurus model was designed by the English polymath Anthony Beeson.

Mike from Everything Dinosaur commented:

“The Rhoetosaurus fossils are hugely significant. These fossils provide important and thus far, the only information on Australian Jurassic sauropods.  By studying these remains palaeontologists can gain a better understanding of sauropod evolution prior to the break-up of Gondwana.”

News of Papo Model Retirements for 2026

By |2026-01-09T14:58:44+00:00January 9th, 2026|Categories: Papo Prehistoric Animal Models|0 Comments

At the start of the year, manufacturers review their inventories and production plans. Papo is no exception.  This French model manufacturer is busy making plans.  To this end, they have announced several Papo prehistoric animal model retirements.  Six figures are out of production and retired:

  • Plesiosaurus (model number 55021)
  • Carnotaurus (model number 55032)
  • Blue Oviraptor (model number 55059)
  • Therizinosaurus (model number 55069
  • Brown running T. rex (model number 55075)
  • Giganotosaurus (model number 55083)

Papo Prehistoric Animal Model Retirements

Of the six figures, the Papo Plesiosaurus and Papo Carnotaurus are the oldest.  For example, the Papo Carnotaurus was introduced in 2013. The blue Oviraptor figure came out in 2017.  It replaced a much older, brown version.  In a similar vein, the brown running Tyrannosaurus rex was launched in 2019, it was a new colour version of an older running T. rex figure. The Papo Therizinosaurus model was introduced in 2019.  It has proved to be a popular model.  The most recently introduced figure to be retired this year is the Papo Giganotosaurus.  It was launched in 2020.

The Papo Giganotosaurus figure attracts controversy. The choice of pose by the designers divides collectors. The pose does not reflect the posture attributed to a theropod dinosaur. However, many collectors find the “hugging posture” endearing.

Mike from Everything Dinosaur comments:

“Whilst we are genuinely sad to see these six Papo prehistoric animal models go out of production, they have enjoyed long and very successful runs and remain popular with collectors. At the same time, these retirements free up valuable production capacity, giving Papo the opportunity to focus on creating exciting new figures. We look forward to seeing what the future holds for this much-loved range.”

New Study Highlights the Oldest Settlements in the British Isles

By |2026-01-07T17:55:12+00:00January 8th, 2026|Categories: Main Page|0 Comments

A hillfort in County Wicklow (Ireland) has been declared the largest known nucleated prehistoric settlement in the British Isles by researchers from Queen’s University Belfast.  The study, published by Cambridge University Press, has won the prestigious Prehistoric Society’s James Dyer prize for 2025.  The research centres around a series of ancient hillforts known as the Baltinglass hillfort cluster.

The research team proposes that the site is Ireland’s earliest proto-town.  This settlement is two thousand years older than the Viking towns that were thought to present the oldest known settlements in Ireland.  The study, funded by UK Research and Innovation, the Natural Environment Research Council and the Prehistoric Society also highlights a possible water cistern at the site.  If confirmed, this would represent the first feature of its kind synonymous with an Irish hillfort.

The “Baltinglass Hillfort Cluster”

A group of prehistoric hillforts known as the “Baltinglass hillfort cluster” has been studied by archaeologists for decades.  These settlements, located in the beautiful and verdant Wicklow County form a “necklace” of thirteen forts.  Seven of these settlements are substantial and described as major hillforts.  Over the years numerous enclosures and evidence of occupation have been identified.  These settlements date from the early Neolithic to the late Bronze Age (circa 3700–800 BC).

Within this cluster, Brusselstown Ring has previously been identified as one of the largest hillforts in Ireland, comprising two large ramparts on neighbouring hill summits – a highly unusual formation in Ireland, Britain or continental Europe.  The site covers an area of 41.9 hectares in total.

The Queen’s University-led study examined existing archaeological data from Brusselstown Ring.  In addition, new fieldwork was undertaken. Survey work carried out revealed 288 potential dwellings.  However, aerial reconnaissance identified at list six hundred topographical anomalies consistent with prehistoric house platforms.  Project team members combined existing data with their own findings to locate nearly a hundred potential roundhouses within the inner enclosure.  Furthermore, evidence of around five hundred more was discovered proximal to the inner enclosure.

Substantial Settlements

Even if not every one of the anomalies represents a dwelling, this would still make it the largest nucleated prehistoric settlement in the British Isles.  For comparison, only a handful of other sites have more than a few dozen roundhouse footprints and not all of them are enclosed, according to lead author of the research project, Dr Dirk Brandherm from Queen’s University Belfast.

Dr Brandherm (School of Natural and Built Environment) confirmed that the fieldwork would continue.  However, if a water cistern is confirmed this would be a significant discovery.

Dr Brandherm stated:

“There has been extensive survey work at the site over the past two decades, but critical questions regarding the date, development and function of both the enclosing elements and the internal settlement remained unanswered, which is why we embarked on this new series of excavations. Our discoveries challenge previous conceptions of prehistoric settlement organisation, showing a level of social complexity, community cohesion, and regional importance not fully recognised before.”

Studies like this help to enrich our understanding of human populations and activity during the Stone Age and into the Bronze Age.  They provide insights into how settlements were established, on social interaction and landscape use.

Radiocarbon Dating Confirms the Age of the Sites

Researchers employed sophisticated radiocarbon dating to assess the age of the sites.  The data suggests occupation at the Brusselstown Ring during the Late Bronze Age, between c.1210 and 780 BC. Previously, the Vikings had been credited with having founded the first towns in Ireland.  Some house platforms thought to have been erected by Viking settlers date from the Iron Age (circa 750 to 400 BC).  However, this new study demonstrates that settlements in County Wicklow are much older.

Commenting on the significance of this research Dr Brandherm added:

“I very much hope that this new knowledge will not only add to our knowledge but help us preserve Brusselstown Ring as a site of major national and international heritage importance, connecting us to the island of Ireland’s deep past. It also opens avenues for further research into prehistoric societal development, helping to fill gaps in archaeological and historical records.”

The First International Mammoth Conference to be Held in Africa

By |2026-01-10T06:36:00+00:00January 7th, 2026|Categories: Palaeontological articles|0 Comments

For the first time, the International Mammoth Conference heads to Africa. This decision marks a historic milestone. Importantly, it reflects the continent’s deep evolutionary significance. In January 2026, the National Museums of Kenya will host the “International Conference of Mammoths and their Relatives” in Nairobi. Scientists, academics, researchers, and enthusiasts will gather from across the globe. Together, they will share new insights into mammoths, mastodons, and their extinct relatives.

Crucially, proboscideans first evolved in Africa. Fossil evidence suggests the first proboscideans evolved around sixty million years ago (Palaeocene Epoch). Therefore, this setting feels especially fitting. It places cutting-edge research back at the group’s evolutionary roots. Furthermore, two of the remaining extant elephant species are in Africa.  Many proboscidean lineages evolved in Africa.  For example, deinotheres (family Deinotheriidae) are thought to have originated in Ethiopia.  A favourite Deinotherium figure is the Eofauna Scientific Research Deinotherium model.

The International Mammoth Conference

The “International Conference of Mammoths and their Relatives” is held every four years.  The inaugural conference took place in 1995. This quadrennial international meeting brings together leading researchers in this field of palaeontology. Moreover, conferences like this matter. They help strengthen academic networks beyond Europe and the United States. They also inspire regional students and researchers. As a result, interest in the natural world can grow more evenly worldwide.

Ultimately, this conference celebrates science, collaboration, and Africa’s vital role in palaeontology.

Mike from Everything Dinosaur commented:

“We wish the organisers and everyone attending an enjoyable and most rewarding conference.  It is great to see that this event is being held in Africa.  Perhaps, the conference will lead to greater cooperation between African universities and museums and their counterparts in Europe and North America.”

A New Parvicursorine Theropod from the Gobi Desert is Described

By |2026-01-07T15:02:24+00:00January 6th, 2026|Categories: Palaeontological articles|0 Comments

In the last few days of 2025, a bizarre new dinosaur taxon was scientifically described.  Researchers have published a paper about a fragmentary skeleton from the Upper Cretaceous (Maastrichtian) Nemegt Formation at Khermeen Tsav in the Gobi Desert of Mongolia.  Named Manipulonyx reshetovi, it has been assigned to the Parvicursorinae subfamily of the Alvarezsauridae.  The specimen includes an articulated and complete forelimb and crucially much of the manus (hand).  The single, large digit (digit I) is preserved.  However, evidence of rudimentary side fingers and a complete series of proximal carpal bones are also preserved.  This is the first time that proximal carpal bones have been identified in a parvicursorine.

Manipulonyx reshetovi

With the description of this new parvicursorine, palaeontologists have a much better understanding of the hand anatomy of this type of dinosaur.  In addition, they have hypothesised that parvicursorines specialised in eating eggs.  Therefore, the short forelimbs ended in highly specialised appendages that permitted these little theropods to hold and puncture the eggs of other dinosaurs.

The fossilised material consists of a pair of cervical vertebrae, one dorsal vertebra, sacral vertebrae and caudals. Moreover, the field team recovered fragmentary bones representing hindlimbs and part of the pelvic girdle. In contrast to the scrappy nature of this material, most of the bones from both forelimbs were found. The carpal bones indicate the presence of unique spikes on the wrist that would have helped this dinosaur to grasp and manipulate eggs. The enlarged claw on the powerful first digit is thought to have been used to puncture eggs so that the contents could be consumed.

Previous discoveries have suggested that parvicursorines could have been specialised insectivores.  It had been proposed that their specialised hands had evolved to help them dig for insects or for breaking into termite mounds.  For example, in 2022 we wrote an article about Dzharaonyx eski from Uzbekistan.

To read Everything Dinosaur’s blog post: The Remarkable “Old Dzharakuduk Claw”.

Were Some Alvarezsaurids Ovivores?

Alvarezsaurids are an unusual group of maniraptoran theropods. They evolved long hind limbs, compact bodies, and extremely reduced forearms. However, these arms were not useless. Instead, they supported a powerful, specialised manus. In most species, the hand appears adapted for a single dominant claw. This unusual body plan sets alvarezsaurids apart from all other theropods.

Within this family, Manipulonyx reshetovi belongs to the subfamily Parvicursorinae. These dinosaurs are typically lightly built and highly cursorial. Moreover, they show extreme forelimb modification. However, Manipulonyx goes much further. Its forelimbs preserve the wrist, metacarpals, and digits in near-complete condition. Notably, the manus shows reinforced elements and distinctive bony spikes. Therefore, researchers can assess how the hand functioned in life, not just how it looked.

The scientists writing in the Proceedings of the Zoological Institute of the Russian Academy of Sciences speculate that M. reshetovi was an egg-eater (ovivore).  This hypothesis builds on earlier discussions about alvarezsaurid diets.  For example, back in 2018 we authored an article about Qiupanykus zhangi, an alvarezsaurid from central China. At the time, it was speculated that Qiupanykus was an ovivore.

To read the blog post on Q. zhangiDid Alvarezsaurids Eat Eggs?

Mike from Everything Dinosaur commented:

“Manipulonyx reshetovi provides a rare and valuable window into parvicursorine evolution. Above all, its well-preserved forelimbs transform how we interpret alvarezsaurid behaviour and feeding strategies.  The forelimb is the most completely known of any parvicursorine and its discovery highlights the incredible diversity of the Dinosauria.”

The scientific paper is published in Proceedings of the Zoological Institute of the Russian Academy of Sciences.

New Nanmu Studio Saltwater Crocodile Figures Announced

By |2026-01-07T09:44:56+00:00January 5th, 2026|Categories: Nanmu Studio Models|0 Comments

New Nanmu Studio saltwater crocodiles have been announced. A pair of articulated saltwater crocodile figures will be available in 2026.  Collectors and fans of Nanmu Studio can choose from the “Lord of Blood” or “The Omen King”.  The Nanmu Studio saltwater crocodiles have twenty-nine points of articulation.  Furthermore, the models measure around thirty-five centimetres long.  Based on an adult male saltwater crocodile measuring around five metres, we estimate a scale size of around 1:15.

These two crocodilians will be available late in quarter two or possibly quarter three.

Nanmu Studio offers two saltwater crocodile figures (“Lord of Blood” and “The Omen King”). Each model has twenty-nine points of articulation but a different colour scheme.

To view the extensive range of Nanmu Studio models offered by Everything Dinosaur: Nanmu Studio Models.

Models of Crocodylus porosus are a departure for Nanmu Studio.  The company normally focuses on extinct animals or replicas of prehistoric animals that have featured in movies.  However, the world’s largest crocodilian would certainly be at home in a world dominated by dinosaurs.  The phylogeny of ancestral crocodilians that led to modern, extant genera (Neosuchia) is disputed. Ancestral forms may have been present in the Early Jurassic.

The range of the saltwater crocodile is extensive.  It has the largest geographical range of any living crocodile.  These reptiles range from Sri Lanka, along the India coastline, through south-eastern Asia, Papua New Guinea and to the northern coast of Australia.  It is extremely aggressive and attacks on people do occur.

Two Nanmu Studio Saltwater Crocodiles

Each figure has twenty-nine points of articulation. The two figures have different colour schemes.  The “Lord of Blood” figure for example, has a greenish tinge.  The colouration of saltwater crocodiles can vary considerably.  It seems logical to offer two figures with different colouration.

The Largest Living Reptile

The saltwater crocodile is at home in fresh, brackish and saltwater.  It is sometimes referred to as the estuarine crocodile.  Males are bigger than females and the largest captive specimens can reach lengths in excess of six metres.  Even larger individuals have been reported. It is the largest extant reptile.

The Remarkable Titanosaur Utetitan and the Return of Giant Sauropods to North America

By |2026-01-03T21:59:27+00:00January 4th, 2026|Categories: Palaeontological articles|0 Comments

The recent description of Utetitan zellaguymondeweyae marks a significant step forward in Late Cretaceous dinosaur research. This newly recognised titanosaurian sauropod lived during the Maastrichtian fauna stage in what is now Utah. Importantly, it challenges long-held assumptions about sauropod diversity in what we now know as North America.

For many years, palaeontologists believed that Alamosaurus sanjuanensis was the only sauropod present in North America during the final few million years of the Cretaceous. This idea always raised questions. After all, sauropods elsewhere often show multiple species living side by side. A single species persisting unchanged for such a long time seemed implausible.

The fossils that led to description of Utetitan come from the North Horn Formation, which dates to the very end of the Age of Dinosaurs. Although these remains were collected decades ago, they were historically placed within the Alamosaurus taxon. At the time, comparisons were difficult. Most sauropod fossils from the southwest and northern Mexico are fragmentary. Overlapping bones are rare. In addition, it is often difficult to compare fossil skeletons as they represent individuals at different growth stages.

Utetitan zellaguymondeweyae

Recent re-examination of the material revealed something important. The Utah fossils differ consistently from Alamosaurus fossils found in New Mexico. These distinctions are anatomical, not simply related to ontogeny or taphonomy. As a result, the Utah skeleton was designated as the holotype of a new species, Utetitan zellaguymondeweyae.

The name Utetitan honours the native Ute peoples of the region. Whereas the species name honours the author’s (Gregory S. Paul) maternal grandmother Zella Guymon Dewey (1901–2002).

The holotype includes tail vertebrae, pelvic bones, limb elements, and a distinctive osteoderm. Consequently, Utetitan is one of the most informative Late Cretaceous sauropods known from North America. Its anatomy confirms its place within the Titanosauria clade.

Many Different Titanosaurs Lived in Late Cretaceous North America

Crucially, Utetitan changes how palaeontologists view Late Cretaceous ecosystems. Evidence now suggests that multiple titanosaurs lived in southwestern North America during the Campanian and Maastrichtian faunal stages of the Late Cretaceous. Furthermore, some fossils from Texas may belong to Utetitan. Other fossils do not. Older Campanian remains cannot be confidently assigned to either Alamosaurus or Utetitan. This suggests that there are many more titanosaur genera awaiting scientific description.

These titanosaurs may even represent a short-lived regional lineage. In semi-isolation, they could have evolved separately from titanosaurs elsewhere in the world. Interestingly, new skeletal reconstructions suggest that these animals were not as massive as earlier size estimates indicated.

From a biogeographical perspective, Utetitan supports the idea of late sauropod migrations into North America. Changing sea levels may have opened temporary land corridors. Through these routes, titanosaurs could disperse from other continents.

Ultimately, the Utetitan zellaguymondeweyae paper shows how revisiting old fossils can transform scientific understanding.

Rare Azhdarchid Pterosaur Fossils From the Gobi Desert

By |2026-01-03T16:08:54+00:00January 3rd, 2026|Categories: Palaeontological articles|0 Comments

Palaeontologists have described two new species of azhdarchid pterosaurs from Mongolia’s Gobi Desert. The Gobi Desert is famous for its numerous dinosaur fossils. However, pterosaur remains are very rare in Mongolian Mesozoic deposits. Researchers writing in the academic journal “PeerJ” identified azhdarchid pterosaur fossils.

The material consists of bones from the neck, and from these specimens two new species have been erected. The fossils come from two different localities (Bayshin Tsav and Burkhant). Originally collected in the 1990s, the fossils were described in detail in 2009 (Watabe et al). Yet, at the time the pterosaurs were not named, just described as indeterminate azhdarchids.

Azhdarchid Pterosaur Fossils

Subsequently, knowledge of azhdarchid pterosaur anatomy has improved. As a result, two distinct species have been named.  In a paper published in the autumn, researchers identified diagnostic features permitting the establishment of these two new species. The paper was written by researchers from the Universidade de São Paulo (Brazil), Shihezi University (China) and Hokkaido University (Japan).

Gobiazhdarcho tsogtbaatari: A Medium-Sized Pterosaur

The first species is named Gobiazhdarcho tsogtbaatari. It comes from the Burkhant locality of the Bayanshiree Formation. This pterosaur had an estimated wingspan of three to three and a half metres. It has been described as a medium-sized azhdarchid, with a wingspan roughly comparable to an Andean Condor (Vultur gryphus).  Fossils associated with this taxon include an atlantoaxis (fused neck vertebrae) and other cervical bones. These show it belonged to a lineage related to giants such as Quetzalcoatlus and Arambourgiania. In evolutionary terms, Gobiazhdarcho is a basal member of this quetzalcoatlid group, bridging gaps in the fossil record.

Its name reflects both its origin and scientific heritage. “Gobi” refers to the desert where it was found. “Azhdarcho” comes from Persian for dragon. The species name honours Mongolian palaeontologist Khishigjav Tsogtbaatar.

Tsogtopteryx mongoliensis: A Small Azhdarchid Pterosaur

The second species named in the paper is Tsogtopteryx mongoliensis. This pterosaur is notably small for an azhdarchid. Its estimated wingspan was approximately two metres, making it one of the smallest members of the Azhdarchidae family.  A single, partial mid-cervical vertebra is known for this species. Despite the limited material, distinct features show it belongs to a different pterosaur lineage than Gobiazhdarcho.  It was related to Hatzegopteryx. This lineage includes robust-necked azhdarchids previously known only from Europe.

The genus name combines the Mongolian word “Tsogt” (meaning mighty hero) with the Greek word pteryx which means wing. The species name references its discovery in Mongolia.

Azhdarchids Occupied Diverse Ecological Niches

The coexistence of Gobiazhdarcho and Tsogtopteryx in the same geological formation emphasises that azhdarchids occupied diverse ecological niches. Different body sizes suggest varied foraging behaviours and diets. This pattern echoes findings from other Upper Cretaceous deposits.  This study sheds fresh light on the diversity and phylogeny of azhdarchid pterosaurs. It reinforces the reoccurring pattern of coexistence between multiple, differently-sized azhdarchid species within the same palaeoenvironment.

A New Chinese Ornithopod Model from PNSO

By |2026-01-02T18:58:47+00:00January 2nd, 2026|Categories: PNSO Age of Dinosaurs Models|0 Comments

PNSO announces a new Chinese ornithopod dinosaur model for 2026.  Everything Dinosaur will be stocking this figure (Lanqi the Lanzhousaurus) shortly. This herbivorous dinosaur was described in the Geological Bulletin of China in September 2005.  It is famous for having over-sized teeth, far larger than the teeth of similarly sized ornithopods such as Iguanodon bernissartensis.

The model represents an Early Cretaceous ornithopod from central China.  It was a robust animal with an estimated body length of around ten metres and a body weight of approximately six tonnes.  The PNSO Lanzhousaurus model measures 25.8 cm in length.  We are not aware of any declared scale, but we calculate that based on an adult animal being around ten metres long, this figure is in roughly 1:40 scale.

PNSO Lanzhousaurus model measurements.

The Lanzhousaurus model measures over twenty-five centimetres in length.

The type specimen is reference number GSLTZP01-001, and it represents a partial skeleton with both cranial and postcranial material.  Remarkably, the bones of this dinosaur were preserved in 3D and do not have much lateral compression.  Its type locality is Zhongpu, Lintao county in Gansu Province.  It is thought the deposits from where the fossils were excavated date from the Barremian/Aptian.  When formally described (You, Ji and Li), Lanzhousaurus was differentiated from other iguanodontians in possessing extremely large teeth and a low tooth count per tooth row (fourteen). The dorsal neural spines were described as being moderately tall.

Mike from Everything Dinosaur commented:

“We are delighted to see that this remarkable dinosaur is going to be added to the PNSO range.  It had the largest known teeth of any herbivorous dinosaur known to science.”
