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 Bisticeratops is a genus of chasmosaurine ceratopsian dinosaur that lived in North America during the late Cretaceous. First named from only a skull, Bisticeratops seems to have been quite typical of the chasmosaurine ceratopsians. Further Reading - A new chasmosaurine ceratopsid from the Upper Cretaceous (Campanian) Farmington Member of the Kirtland Formation, New … Read more
Discovery and Early Reconstruction of Iguanodon Iguanodon has a firm place within dinosaur history books, not just because of the large expanse of fossil material attributed to it, but because it was the second dinosaur to ever be identified and named. The first dinosaur was actually Megalosaurus which was named a year earlier, and back then the term … Read more
In Depth Sierraceratops is a genus of ceratopsian dinosaur that lived in North America during the late Cretaceous. Sierraceratops is also considered to have been a chasmosaurine ceratopsian, the kind noted for having proportionately larger neck frills than other ceratopsian types. Further reading - The ceratopsian Torosaurus from the Upper Cretaceous McRae Formation, Sierra County, … Read more
