In Depth With greatly elongated fingers the hands are a tantalising find for palaeontologists, but without the rest of the skeleton it is impossible to give an accurate insight into this creature’s life. One possible explanation is that Yixianosaurus lived like a modern day aye-aye. Aye-aye’s also have hands that have impressively long fingers which … Read more

In Depth Sonorasaurus may look like an atypical brachiosaurid dinosaur (as in similar to the famous Brachiosaurus), but the genus actually represents the first known example of a brachiosaurid dinosaur in North America during the Cretaceous, specifically around the early/late Cretaceous boundary. This is yet further evidence that counters the now outdated theory that the … Read more
In Depth Originally described as belonging to a species of Megalosaurus in 1884, Friedrich von Huene renamed the fossils of teeth and vertebrae to Altispinax in 1923. This name reflects the size of the neural spines of the vertebrae, fossils that were later attributed to the genus after it was established upon the description of … Read more
In Depth The forward dentition of Coloborhynchus was quite special with the front two teeth pointing forwards, and the immediate three pairs of teeth behind them pointing to the sides. This tooth arrangement would have made it much easier for Coloborhynchus to catch and carry fish out of the water. The remaining teeth behind the … Read more
In Depth It is something of a paradox that one of the most popular dinosaurs of all time is understood by some of the most incomplete fossil remains. What can be gleaned from the available fossil material is that Ankylosaurus was one of if not the largest of the group. The incomplete fossil evidence however … Read more
In Depth Arganaceras was a pareiasaur that lived in Morocco during the late Permian. Like relative genera, Arganaceras would have been quadrupedal herbivores. A particularly close relative of the genus may have been Elginia. Further Reading - Les pareiasaures (Amniota, Parareptilia) du Permien sup�rieur du Bassin d’Argana, Maroc - N.-E. Jalil & P.

In Depth Edgarosaurus seems to have been one of the first polycoylid plesiosaurs to swim in the late Cretaceous Western Interior Seaway, a shallow sea that submerged much of central North American during the Cretaceous. Like its relatives, Edgarosaurus had a typical plesiosaur body but a short neck an elongated jaws, features reminiscent of the … Read more
In Depth It is quite surprising when you think about how Aublysodon is represented in so many dinosaur books and internet sources even though back when it was described in 1868 it was only from teeth. Still this was a sign of the times back then with other discoveries such as Troodon, which was also … Read more
