In Depth Sinankylosaurus is a genus of ankylosaur that lived in Asia during the late Cretaceous. Though only known from partial remains, the presence of Sinankylosaurus again illustrates the similarity of animal fauna between Asia and North America during the late Cretaceous. Further Reading - A new ankylosaurian from the Late Cretaceous strata of Zhucheng, … Read more
In Depth Dromaeosauroides is what is called a ‘tooth taxon’ as so far this dinosaur only has fossil teeth attributed to it. These teeth seem to come from a dromaeosaurid theropod dinosaur, and this is reason why for the name which means Dromaeosaurus-like. Comparison of these teeth to those of other dromaeosaurids suggests that Dromaeosauroides … Read more
In Depth Venenosaurus, meaning ‘poison lizard’ acquired its name from being discovered in the Poison Strip Member of the Cedar Mountain Formation, while the type species, V. dicrocei, is in honour of Tony DiCroce, the person who first discovered the remains. Other sauropod dinosaurs from the Cedar Mountain Formation, albeit from different Members, include Abydosaurus, … Read more
In Depth Smaller velociraptorine dromaeosaurs seem to have been one of the most important types of dinosaur in Asia during the Late Cretaceous as evidenced by the ever growing number of remains and genera. Linheraptor was similar in form to most others such as Velociraptor and it may have lived and hunted in pretty much … Read more
In Depth Edmontosaurus is without a doubt one of if not the most intensively studied hadrosaurid dinosaur. Not only are there many Edmontosaurus specimens known, but those that have been recovered include some of the best preserved hadrosaurid material so far found.Classification history Edmontosaurus has one of the longest and most complicated taxonomic histories of … Read more
In Depth Yehuecauhceratops is a genus of ceratopsian dinosaur that lived in North America during the late Cretaceous. The holotype individual of Yehuecauhceratops was discovered in the Aguja Formation of Mexico, and in life is thought to have been similar to nasutoceratopsine ceratopsian dinosaur genera such as Nasutoceratops and Avaceratops. Unfortunately because of the lack … Read more
In Depth Fulgurotherium is a little known genus of Australian dinosaur that is also known from very little fossil material; at the time of writing, only a fragment of a femur. This femur seems to match up small ornithopod dinosaurs that range about one to one and a half meters long in size, but this … Read more
In Depth In 2006 the palaeontologists M. Sadiq Malkani described five new genera of titanosaur, Marisaurus, Balochisaurus, Sulaimanisaurus, Khetranisaurus and Pakisaurus, all from caudal vertebrae. From these only Marisaurus and Balochisaurus have had skull remains attributed to them, and only Marisaurus has (partial) rear limb bones attributed to the genus. Marisaurus and Balochisaurus were also … Read more
In Depth Uberabatitan is a genus of titanosaurid sauropod dinosaur that is known from the Marilla Formation of the bauru group of Brazil. Being Maastrichtian in age, Uberabatitan would have been one of the last titanosaurs to live before the KT extinction ended the reign of the dinosaurs. Further Reading - Uberabatitan ribeiroi, a new … Read more
In Depth Tawa is yet another dinosaur genus from the late Triassic of the Ghost Ranch North America, and as you might expect, one quite primitive in form. Tawa were bipedal dinosaurs of the theropod line, noted for having femurs that were proportionately quite long when compared to the lower leg bones. Tawa also had … Read more
