In Depth Corythoraptor is a genus of oviraptorid dinosaur that lived in China during the late Cretaceous. Corythoraptor has been described as having a head crest similar to that of a modern day cassowary. The beak of Corythoraptor was also more pointed towards the end, suggesting feeding specialisation. Corythoraptor is one of many oviraptorid dinosaurs … Read more
In Depth Pristichampsus is a crocodile that bears all of the hallmarks of a terrestrial lifestyle rather than an aquatic one like todays crocodiles. The key clues to this lifestyle can be seen in the legs which are longer than those of semi-aquatic crocodiles to allow for more terrestrial locomotion. Additionally the ends of the … Read more
In Depth Nicrosaurus is another one of the phytosaurs, reptiles that have a striking similarity to modern crocodiles, although the position of the nostrils higher up the snout and in front of the eyes is a dead giveaway that Nicrosaurus is a phytosaur (crocodiles have their nostrils on the tips of their snouts). Nicrosaurus is … Read more
In Depth The fragmentary nature of Shaochilong resulted in it being included into the Chilantaisaurus genus, a theropod dinosaur also from the Ulansuhai Formation. However while fragmentary, the fossil remains for C. maortuensis were much larger that the estimated length of two and a half meters for other Chilantaisaurus material. Questions were first raised about … Read more
In Depth Thalassomedon is regarded as a mid-sized elasmosaurid plesiosaur, especially when compared with larger genera like Mauisaurus. The distribution of Thalassomedon remains show that it swam in the Western Interior Seaway, a Cretaceous sea that divided North America into two halves. Thalassomedon is so far only known from the early stages of the Late … Read more
In Depth Rhamphosuchus is thought to have looked like a modern day false gharial, crocodiles that have proportionately thin and long snouts compared to other crocodiles.Rhamphosuchus itself however was much larger, although to what extent remains uncertain. This is because Rhamphosuchus is currently only known from very fragmentary material that makes reconstruction of the skull … Read more
In Depth When fossils of this dinosaur were originally described as Lambeosaurus laticaudus, the estimated size of the species was given as between fifteen and sixteen and a half meters long, something that causes inaccurate size quotations for Lambeosaurus to this day even though larger individuals of this genus are around the nine meter mark. … Read more
In Depth Certainly one of the more difficult dinosaur names to pronounce, Mnyamawamtuka is a genus of titanosaur that lived in Africa during the Cretaceous. The holotype of Mnyamawamtuka is recognised as one of the most complete titanosaurs ever discovered. The high level of completeness may be down to the fact that this creature was … Read more
In Depth Chromogisaurus is a genus of sauropodomorph dinosaur that lived in South America during the late Triassic. At only about two meters long, Chromogisaurus was small for its kind, though certainly not unique. The main predators of Chromogisaurus would have mainly been the emerging theropod dinosaurs, though late surviving rauisuchians would have been potential … Read more
In Depth Weewarrasaurus is a genus of ornithischian dinosaur that lived in Australia during the late Cretaceous. At the time of writing, Weewarrasaurus is known from only two dentaries’ (lower jaws), so precise details about this dinosaur are otherwise unknown.
