In Depth Mei was named because it was found in a sleeping pose, not unlike birds today. Study of the bones has revealed they were not totally fused, meaning that the animal was a juvenile. Analysis of the stone the fossil was discovered in shows it to have been buried by volcanic ash. A second … Read more
In Depth Alwalkeria was originally named in 1986 as Walkeria, however the genus name Walkeria was later found to be as preoccupied as it had already been used to name a bryozoan (a kind of tiny aquatic invertebrate). This necessited a revision to the name since naming priority is always given to the first creature … Read more
In Depth Corythoraptor is a genus of oviraptorid dinosaur that lived in China during the late Cretaceous. Corythoraptor has been described as having a head crest similar to that of a modern day cassowary. The beak of Corythoraptor was also more pointed towards the end, suggesting feeding specialisation. Corythoraptor is one of many oviraptorid dinosaurs … Read more
In Depth The fragmentary nature of Shaochilong resulted in it being included into the Chilantaisaurus genus, a theropod dinosaur also from the Ulansuhai Formation. However while fragmentary, the fossil remains for C. maortuensis were much larger that the estimated length of two and a half meters for other Chilantaisaurus material. Questions were first raised about … Read more

Retrieval of this claw also resulted in the recovery of associated bones that revealed a new and previously unknown type of theropod dinosaur. Alan Charig and Angela Milner described and formerly named the new dinosaur Baryonyx … Read more
In Depth Ambopteryx is a genus of scansoriopterygid dinosaur that lived in Asia during the late Jurassic. The name Ambopteryx means ‘both wing’ and this is a reference to the observations that fossil impressions with the holotype skeleton show that Ambopteryx was feathered, but then had bat-like membranous wings which were not feathered as well. … Read more
In Depth Sinornithoides is a genus of small troodontid dinosaur that lived in China during the early Cretaceous. The holotype individual of this genus, a subadult, was found in a nesting position with its head tucked under its left arm, very similar to how another small troodontid named Mei was found. This may indicate that … Read more
In Depth Leptorhynchos is based upon the description of caenagnathid oviraptorid dinosaur remains discovered in the Aguaja Formation of Texas, establishing the type species L. gaddisi. At the same time as this description, fossils from the Dinosaur Park Formation of Alberta and originally attributed as a species of Ornithomimus, O. elegans, have also been re-described … Read more

This genus was Laquintasaura, a small plant eating ornithischian dinosaur, fossils of which were discovered where a road was being cut into the Venezuelan landscape. However, when Laquintasaura was discovered, the teeth of small theropod dinosaurs were also … Read more
