Archaeornithoides: Research Database Troodontidae (Theropoda) · Late Cretaceous (~80-73 MYA) · Asia — Mongolia (Gobi Desert, Djadokhta Formation) Research Note: Archaeornithoides was a troodontid theropod from the Late Cretaceous of Mongolia — a small, bird-like dinosaur and an important taxon for understanding troodontid diversity and the dinosaur-bird transition in the latest Cretaceous of Asia. … Read more
In Depth Originally named as Elaphrosaurus gautieri in 1960, a 2004 analysis of the remains by P. C. Sereno, J. A. Wilson and J. L. Conrad concluded that they belonged to a different genus of dinosaur. Hence forth this fossil material now goes by the name of Spinostropheus based upon the shape of the vertebrae, … Read more
In Depth Goyocephale was a mid-sized genus of pachycephalosaurid dinosaur that is known to have lived in what is now Mongolia during the Cretaceous. Goyocephale is noted for having a flat skull as opposed to a more ornate dome which is characteristic of other genera such as Pachycephalosaurus and Prenocephale. This could indicate that the … Read more
Magyarosaurus: Research Database Titanosauria (Sauropoda) · Late Cretaceous (~70-66 MYA) · Europe — Romania (Hațeg Basin) Research Note: Magyarosaurus was a dwarf titanosaur from the Late Cretaceous of Romania — an example of island dwarfism and an important taxon for understanding titanosaur evolution and the effects of insularity on dinosaur body size. Research … Read more

In Depth Ahshislepelta is a genus of ankylosaurid dinosaur that lived in North America during the late Cretaceous. Unfortunately the partial remains of Ahshislepelta which include a shoulder girdle, partial left forelimb, vertebrae and osteoderms (the bony armour) are not enough to identify the genus as either a general ankylosaurid or a more derived ankylosaurine. … Read more
Valdosaurus: Research Database Dryosauridae (Ornithischia) · Early Cretaceous (~140 MYA) · Europe — England (Wealden Group) Research Note: Valdosaurus was a small, agile dryosaurid ornithopod from the Early Cretaceous of England — one of the few known dinosaurs from the Wealden Group of mainland Britain. As a dryosaurid, it was a relatively small, fast-running … Read more
In Depth Although based only upon the description of the braincase, it has been enough to not only identify Nebulasaurus as a new eusauropod dinosaur, but also further hints that during the middle Jurassic Asia had a very diverse range of sauropod dinosaurs. By the late Jurassic this diverse range seems to have thinned out … Read more
Philovenator: Research Database Troodontidae (Theropoda) · Early Cretaceous (~120 MYA) · Asia — China (Yixian Formation, Liaoning) Research Note: Philovenator was a troodontid theropod from the Early Cretaceous Yixian Formation of Liaoning, China. As a small paravian theropod, it provides important data on the diversity and evolutionary relationships of troodontid dinosaurs in the Early … Read more
