In Depth Magnirostris was a protoceratopsid dinosaur that would have been similar to the much more famous Protoceratops. Magnirostris was named after the unusually large beak that can be clearly appreciated in the holotype specimen. There has been suggestion that the Magnirostris holotype may in fact belong to the Bagaceratops genus. The thinking behind this … Read more
In Depth Silvisaurus is to date only known by a partial skeleton, and this is in a poor state of preservation that was weathered and trampled by cattle for a long time before it was discovered. Despite the poor state of preservation, Silvisaurus is considered to have been a primitive form of nodosaur that maybe … Read more

In Depth Sarcolestes is a genus of ankylosaur that lived in England during the mid-Jurassic. Unfortunately the only part of this dinosaur that is known is a lower jaw bone, so it is difficult to infer much more about this dinosaur. The lack of fossil remains has also cast doubt upon the validity of this … Read more

In Depth Once again the term ‘wastebasket taxon’ looms like a spectre over another dinosaur. Many of the fossils that were once attributed to Camptosaurus have since been found to represent other dinosaurs, and this is especially true for the European species that were once assigned to Camptosaurus. Despite this reduction in species and geographic … Read more
In Depth Acristavus was a late surviving hadrosaurid that stood out from amongst the others of its kind because it had no head ornamentation. Although not strictly unique, many of the other better known hadrosaurids such as Parasaurolophus and Lambeosaurus had very elaborate and impressive head crests. The fact Acristavus did not have one suggests … Read more
In Depth While Animantarx may not be the best known nodosaurid dinosaur, it is a contender for having one of the coolest dinosaur names. Unfortunately Animantarx is only known by an incomplete skull, lower jaw and some vertebrae, which means that reconstructions are reliant upon other nodosaur parts and a best guess by the reconstructions. … Read more
In Depth Notohypsilophodon is a genus of small ornithopod dinosaur that lived in South America during the late Cretaceous. Notohypsilophodon is so named based upon a superficial similarity to the genus Hypsilophodon while also recognising the more southern occurrence of this individual. Notohypsilophodon is so far only known from the partial remains of a juvenile, … Read more
In Depth Lapampasaurus is a late Cretaceous era genus of hadrosaur. Although only named from partial remains, the discovery is of yet another hadrosaur from South America. The continent of South America has long been assumed to have been isolated from North America during the Cretaceous, but the presence of hadrosaur genera such as Lapampasaurus, … Read more
