In Depth The description of Napaisaurus was based upon partial remains that were considered to represent an iguanodontian dinosaur. If this is correct, then Napaisaurus would be the first of its kind discovered in China. Napaisaurus would have been a mostly quadrupedal dinosaur, maybe occasionally bipedal, that browsed upon plants. Further reading - First new … Read more

In Depth Albalophosaurus has been described as a basal ceratopsian dinosaur, but one that shows similarities to other ornithopod dinosaurs, particularly in dental morphology. This may suggest that Albalophosaurus was a particularly primitive ceratopsian dinosaur, perhaps even one that hints at the transition from ornithopod ancestors to more derived ceratopsian descendants. The name Albalophosaurus means … Read more

In Depth Though only described from a single rib, the dinosaur Spicomellus has generated a lot of interest. First is the original assessment that Spicomellus represents a primitive ankylosaur, and if true this would not only help to build a pattern of development of this dinosaur lineage all the way back into the Jurassic, something … Read more
In Depth Sinocephale fossils originally started as being assigned as a species of Troodon back in 1953 when similarity between the teeth of Troodon and other pachycephalosaurs. When the pachycephalosaurs and troodonts were realised to be very different kinds of dinosaurs, material of Sinocephale was then associated with the pachycephalosaur Stegoceras in 1964. The validity … Read more
In Depth Ibirania is a genus of titanosaurian dinosaur that lived in South America during the late Cretaceous. While South America is known to have at times been home to some truly giant titanosaurs, Ibirania is at the extreme polar opposite of the size scale. Though incomplete, reconstructions of the holotype individual suggest Ibirania was … Read more
