Ammonite fossils are extraordinary. Often, the preserved shells of these marine invertebrates are amongst the first fossils acquired when starting a fossil collection. Sue and I (Everything Dinosaur) field questions about ammonites frequently. We do our best to respond to all the emailed enquiries we receive. In addition, we have collected large numbers of ammonite fossils ourselves. Visitors to our offices and warehouse can be given a fossil from our collection as a souvenir of their visit. Ammonite fossils are a favourite. Moreover, we have commissioned an ammonite diagram.
The preserved shells do not give an impression of the animal. These cephalopods are known from their ubiquitous fossilised shells but very few specimens showing the actual animal have been found. However, we have created a helpful diagram that depicts a living ammonite. Furthermore, we have labelled our illustration.

The ammonite is shown in lateral view. The visible parts of the animal outside the shell are coloured. The shell (often preserved as a fossil), is shown in monotone. In addition, we have provided helpful labels. We could produce a more sophisticated diagram. However, we have refrained from doing so as the majority of our ammonite enquiries come from junior/primary school teachers and young fossil collectors.
Our drawing is based upon the Bullyland ammonite figure. This model is popular with fossil collectors. It is often included inside ammonite fossil display cabinets.

Mike from Everything Dinosaur commented:
“Ammonites are fascinating. Their fossils are important markers in biostratigraphy and helpful in relative dating. Remarkably, these molluscs did not die out at the end of the Cretaceous. There is evidence to indicate that a few taxa survived into the Palaeocene. What amazing invertebrates!”

A comprehensive overview of T. rex ontogeny has been published in the open access journal PeerJ. This research suggests that Tyrannosaurus rex could have taken around forty years to reach full size. The study suggests that the Tyrannosaurus rex species grew more gradually and over a longer lifespan than indicated by prior models, with a protracted period of subadult development. Knowing more about the ontogeny (growth) of dinosaurs like T. rex will help scientists to better understand how this iconic predator may have lived and how it interacted with prey species. In addition, this research has implications with regards to the current debate over the Nanotyrannus taxon.
Previous studies had indicated that Tyrannosaurus rex grew rapidly and that it had a series of dramatic growth spurts before reaching adult size at around twenty-five years of age. In 2015, the reboot of the “Jurassic Park” franchise occurred. In the film “Jurassic World” a new theropod dinosaur was introduced – Indominus rex. We wrote an article comparing the growth rate of T. rex with this new, fictional theropod. We compared the growth rates proposed for these two theropod taxa. Whilst speculative, it permitted a comparison of I. rex growth based on the fictional movie timeline with the postulated growth rate for a large tyrannosaurid based on the current research. The results are shown in the graph below.

I. rex versus T. rex growth rates. The timeline from the 2015 film “Jurassic World” hinted at an extremely rapid growth rate for the fictional theropod Indominex rex. At the time, research suggested that T. rex grew rapidly too, undergoing a series of growth spurts, particularly in its teenage years before reaching full size at around twenty-five years of age. New research suggests T. rex grew more slowly. Picture credit: Everything Dinosaur.

The article comparing the growth rates of Tyrannosaurus rex and Indominus rex: The Growth Spurts of Tyrannosaurs.
Earlier studies into T. rex ontogeny proposed that the “Tyrant Lizard King” exceeded eight tonnes in weight within two decades and had a lifespan of approximately thirty years. However, this understanding of Tyrannosaurus rex growth dynamics is dependent on single-point histological sampling of multiple skeletal elements and lacks specimens encompassing the earliest growth states.
Corresponding author of the study Dr Holly Ballard (Oklahoma State University), specialises in studying osteohistology (growth patterns of animals preserved in bone tissue) to map population growth dynamics in extinct vertebrates. We have reported on Holly’s research previously. For example, back in 2015, we wrote an article examining research into the growth rates of the dinosaur Maiasaura peeblesorum.
To read this blog post: Examining the Lives of Dinosaurs.
The researchers examined the growth rings preserved in the leg bones of seventeen T. rex. The individuals ranged from juveniles to mature adults. It is the most comprehensive histological analysis of Tyrannosaurus ontogeny to date. Four alternative statistical models were employed. The study indicates that rather than racing to adulthood with remarkable growth spurts, Tyrannosaurus rex grew more slowly and steadily than previously thought.
Co-author of the study John “Jack” Horner (Chapman University, California) explained that a forty-year growth phase may have permitted younger tyrannosaurs to fill a variety of ecological niches within Late Cretaceous palaeoenvironments. Their growth rate could be one factor that permitted this taxon to dominate terrestrial ecosystems as the apex predator.
Many Tyrannosaurus rex models and figures are based on monsters from the movies. Only a few T. rex models are developed based on closely following the scientific evidence. Our own Everything Dinosaur Evolution 1:33 scale Tyrannosaurus rex figure follows the fossil record closely. The model represents a mature, adult animal. Rather than reaching full size at around twenty-five years of age, based on this research, our figure represents a T. rex more than thirty years of age.
According to this study, T. rex could have reached forty years of age. However, very few individuals lived that long. Indeed, only two specimens in the sample of seventeen tyrannosaurs represent adult dinosaurs.

Although Tyrannosaurus rex is the best-known species of this group of dinosaurs, recent studies have proposed that some specimens previously identified as T. rex may in fact be members of other related species. Some scientists, for example, have argued that certain smaller specimens represent a small-bodied species, named Nanotyrannus, rather than juvenile specimens of Tyrannosaurus rex.
The paper’s authors acknowledge the variation in tyrannosaurs. No single, completely uniform growth pattern is highlighted. They acknowledge variation among individual specimens, including ones historically attributed to the Nanotyrannus genus. However, T. rex ontogeny alone cannot prove that the outlying specimens within this dataset represent different taxa. Unusual growth patterns might reflect individual variation or pathology. In addition, the dataset of tyrannosaur specimens is far from complete. To gain greater certainty, a much larger sample would be required.
To read Everything Dinosaur’s blog post from November 2024 featuring details of the paper validating the Nanotyrannus taxon: A New Chapter in Tyrannosaur Evolution.
This new study does challenge current views on T. rex ontogeny. These researchers conclude that the Tyrannosaurus rex species grew more gradually and over a longer lifespan. Few tyrannosaur population members attained their adult size. Furthermore, this research indicates that these predators had a prolonged subadult phase of their lifecycle.

Catching up with some of the latest developments in ornithischian dinosaur research. For example, late last year, a new saurolophine hadrosaurid dinosaur from New Mexico was formally described. Named Ahshislesaurus wimani, it reinforces the view that hadrosaurs were among the dominant large herbivorous dinosaurs present in southern Laramidia during the last ten million years of the Cretaceous.
Picture credit: Sergey Krasovskiy
The research team erected a new hadrosaur taxon based on the study of skull bones as well as postcranial material. The bones that would be identified as Ahshislesaurus were uncovered in San Juan County (northwestern New Mexico), by famed collector John B. Reeside, Jr. in 1916. In 1935, the fossils were classified as belonging to another hadrosaurid named Kritosaurus navajovius. However, this new research identified distinctions between these fossils and all known hadrosaurids, including several key differences in the animal’s skull.
Ahshislesaurus (pronounced Ah-shi-sle-sore-us), is estimated to have reached lengths in excess of eleven metres. It might have weighed more than eight tonnes. The fossil material comes from the lower Hunter Wash Member of the lower Kirtland Formation (Campanian faunal stage). The paper describing the new species was published in the Bulletin of the New Mexico Museum of Natural History and Science. It is a journal managed by the New Mexico Museum of Natural History and Science.
Co-author of the paper, Dr Anthony Fiorillo, Executive Director of the New Mexico Museum of Natural History and Science stated:
“Discoveries like this remind us that science truly is a community. Our team of researchers spanning five institutions and two countries were able to build upon research that started nearly a century ago and now advances our understanding of what our state looked like during the Late Cretaceous Period.”

Dr Fiorillo examined the fossils alongside his colleague Dr Spencer Lucas. In addition, Sebastian Dalman (Montana State University), the lead author and co-authors Steven Jasinski (Harrisburg University), Edward Malinzak (Pennsylvania State University), and Martin Kundrát (Pavol Jozef Šafárik University in Slovakia) were involved in the research.
De Lucas commented:
“It seems like palaeontologists are discovering new dinosaurs in New Mexico every few months. This new hadrosaur just adds to my conviction that there are many, many new dinosaurs still out there waiting to be unearthed!”
To read an article from 2018 about the discovery of a new species of armoured dinosaur in New Mexico: A New Nodosaur from New Mexico.
A new species of chasmosaurine ceratopsian from New Mexico: The Chasmosaurine Bisticeratops.
Although only some isolated skull material has been found, the scientists postulate that Ahshislesaurus lacked a head crest. The skull of Ahshislesaurus wimani preserves several taxonomically informative characters that show close affinities with the stratigraphically younger Naashoibitosaurus ostromi from the De-na-zin Member. Together with Naashoibitosaurus, Ahshislesaurus forms a potentially novel clade of flat-headed saurolophine hadrosaurids. This clade suggests the saurolophines were a taxonomically diverse group, which, during the last twenty million years of the Cretaceous, were among the dominant herbivorous dinosaurs in southern Laramidia.
Scientists are building up a detailed picture of the dinosaur fauna from the Late Cretaceous of New Mexico. Similar types of dinosaurs existed in southern Laramidia as those in more northerly parts of the landmass. However, the genera are different. For example, the herbivorous Ahshislesaurus wimani co-existed with ankylosaurids and horned dinosaurs like Navajoceratops. The apex predator was a tyrannosaur – Bistahieversor.

This new hadrosaur taxon was named for the Ah-shi-sle-pah Wilderness in San Juan County, where its fossils were found. The specific epithet, “wimani”, honours the first Swedish professor of palaeontology, Carl Wiman (1867–1944), from Uppsala University, who worked on fossil vertebrates from the San Juan Basin. Recognition of a new hadrosaurid species from New Mexico also provides further evidence for latitudinal variation in the hadrosaurid fauna during the Late Cretaceous in Laramidia. In addition to the holotype of A. wimani, several specimens from the same strata may also belong to this newly identified species, including a well-preserved left dentary and a partial skeleton, as well as two humeri, one belonging to a large adult and the other to a juvenile.

The Australian sauropod Rhoetosaurus brownei was named and scientifically described a hundred years ago. It remains the only Jurassic sauropod known from Australia. Remarkably, it was the first dinosaur named from Australian fossil material. Rhoetosaurus might not be the best-known sauropod, but we remember the excitement when our friend Anthony Beeson designed a model of this iconic dinosaur for CollectA. Having already added a Brachiosaurus figure to the CollectA range, the CollectA Rhoetosaurus model represented a departure for the company. Firstly, many dedicated and devoted model collectors were unaware of this dinosaur. Secondly, it was the first sauropod figure made by CollectA to be depicted in a rearing pose.
Measuring around seventeen centimetres tall, the CollectA Rhoetosaurus model was introduced more than fifteen years ago. The CollectA Age of Dinosaurs range was growing fast. Models of Tyrannosaurus rex, Triceratops and Stegosaurus existed. However, the Rhoetosaurus demonstrates the manufacturer’s desire to highlight less well-known prehistoric animals. This desire continues today. For example, CollectA will add a phytosaur model, a first for the company.
Mike from Everything Dinosaur commented:
“We applaud the efforts of the design team at CollectA to introduce dinosaur fans and model collectors to some of the more unusual and overlooked members of the Dinosauria.”
To view the extensive CollectA Age of Dinosaurs model range: CollectA Age of Dinosaurs Models.

The CollectA Rhoetosaurus model is also available as a mini dinosaur model. It is part of the sauropod model set introduced by CollectA in 2024.
Rhoetosaurus brownei was scientifically described by Heber Longman. At the time, this distinguished scientist was director of the Queensland Museum. The paper describing Rhoetosaurus was published in the “Memoirs of the Queensland Museum” in March 1926. Remarkably, in conclusion Longman made a prediction about future dinosaur discoveries “down under”.
He wrote:
“In view of the prodigious variety of dinosaurian forms recorded from other parts of the world, illustrating the “bizarrerie” of nature to a degree unsurpassed by any other group, it will not be surprising if many additional forms are found in the future in Australian deposits.”
Given the vast size of Australia and the country’s geology, further dinosaur fossil finds were something of a safe bet. Over the last hundred years a wide variety of dinosaur taxa have been named including sauropods. For instance, Diamantinasaurus matildae, Savannasaurus elliottorum and Wintonotitan wattsi. In addition, the largest Australian terrestrial animal is another sauropod, the gigantic Australotitan cooperensis. However, the taxonomic validity of some genera has been challenged.
To learn more about the confusing taxonomy of Australian sauropods: Describing and Classifying Australian Sauropods.
Although all these sauropods were discovered in Queensland, the same state as the Rhoetosaurus fossil material, none of these dinosaurs were closely related to Rhoetosaurus. Sauropods such as Wintonotitan, Diamantinasaurus and Savannasaurus lived millions of years after Rhoetosaurus had become extinct.
Additional fossil specimens are needed to help resolve and clarify Australian sauropod taxonomy. Heber Longman was proved correct when, back in 1926 he predicted more Australian dinosaur discoveries. However, over a hundred years later, we await a second Jurassic sauropod fossil discovery in Australia.
Perhaps 2026 will change that…

Earlier this month, we highlighted the Papo prehistoric animal models that are going out of production and being retired. Today, we look back at a figure that has captured the hearts of many dinosaur fans. However, it is a controversial figure. The Papo Giganotosaurus model is one of six Papo prehistoric animal figures going this year. Originally introduced in 2020 it will soon be unavailable.
The unusual posture has drawn criticism. Moreover, it certainly stands out amongst other Giganotosaurus models. The Papo Giganotosaurus is an intriguing addition to any collection. Fans loved its bold size and hand-painted detail, which brought this mighty theropod to life. However, the model also sparked lively discussion. Some collectors questioned the figure’s pose. It does not reflect the scientific evidence. Yet, many found the stance charming, endearing and full of character.

It is sad to see this figure go. For many younger collectors, the Papo Giganotosaurus was a gateway into deeper interest in dinosaurs and prehistoric animals. Its retirement reminds us how certain models become more than toys — they acquire a charm all of their own. We will miss it, but its legacy will endure in the collections of dinosaur model fans.
Mike from Everything Dinosaur commented:
“We saw early prototypes of the Papo Giganotosaurus model about twelve months before it went into production. At the time we asked the designers to reconsider their design. However, the project continued. In a way we are glad that the design team did not listen to us. The Papo Giganotosaurus model might not be the most anatomically accurate figure, but it had a certain style, and it reflects that flamboyant Papo panache.”

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.

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.
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.
To view the CollectA not-to-scale model range: CollectA Age of Dinosaurs.
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.”

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:

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.”

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.

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.

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.

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.”
