In Depth Not too much can be said about Tochisaurus because so far it is only known from a couple of foot bones, However these bones do seem to be most similar to those seen in troodontid dinosaurs. Additionally with lengths of about twenty-four and twenty-two centimetres long, the foot bones of Tochisaurus do indicate … Read more
In Depth Patagonia is a hot bed for dinosaur fossils, although it’s usually the dramatic giants such as Giganotosaurus and Argentinosaurus that that take the spotlight. Bonapartenykus was much smaller than these two dinosaurs, however for the purposes of palaeontology and understanding of Mesozoic Patagonia it is at least just as important. First is the … Read more
In Depth Zhejiangosaurus is not completely known, nor does it seem to show any special features beyond being a nodosaurid. This identification is itself important however since the only two other Asian nodosaurids named before this, Zhongyuansaurus and Liaoningosaurus, have now been re-classified as ankylosaurids. At the time of its description this makes Zhejiangosaurus the … Read more
In Depth Leptoceratops is similar in form to the earlier ceratopsian dinosaurs that would evolve into the larger members of the group such as Chasmosaurus and Anchiceratops. However Leptoceratops lived much later than these ancestral forms as indicated by its entry into the fossil record at a time which would have seen Leptoceratops living in … Read more
In Depth Bonitasaura is a genus of what seems to have been fairly small titanosaurs that lived in Argentina during the Late Cretaceous. The holotype individual seems to have been a subadult, which means that while it was sexually mature, it still would not have been fully grown. During this phase of its life though, … Read more
In Depth Equijubus seems to have been a primitive hadrosauroid from the early Cretaceous of China, though some have considered the genus to be more simply an iguanodont. Despite this, the skull of Equijubus lacks a palpebral bone, meaning that the eye did not have a bony projection jutting above it. Further Reading - The … Read more
In Depth Because of a current lack of fossils for this genus, the only thing that can be said with any certainty is that Kerberosaurus was a saurolophine hadrosaurid, the group of hadrosaurs noted to have solid head crests like those of Saurolophus. The skull remains of Kerberosaurus were discovered in a bone bed of … Read more
In Depth At the time of the description in 2017, Zuul was the best preserved ankylosaurine ankylosaur ever found in North America. Not only was the skull and post cranial skeleton mostly complete, many of the armoured plates that adorned its back were still present. The type species name, Z. crurivastator, is Latin and basically … Read more
In Depth With fossils going back to the mid Jurassic, it comes as no surprise that Huayangosaurus is a more primitive stegosaur than better known genera from the late Jurassic. The skull of Huayangosaurus is broader than later forms which reveals it was not as well adapted to selective browsing. The premaxilla also still has … Read more
In Depth Panguraptor is the first genus of coelophysid dinosaur discovered on the Asian continent. Panguraptor was a small predator that would have hunted small animals. Panguraptor was also the second definitive dinosaur genus named from the Lufeng Formation, the first being Sinosaurus. Further Reading - The first well-preserved coelophysoid theropod dinosaur from Asia. - … Read more
