In Depth Tralkasaurus was named from very partial fossil remains, so it is hard to be certain and the full life features of this dinosuar. At the time of discovery, what can be said is that Tralkasaurus seems to have been an abelisaurid theropod, and one that seems to have been smaller than most other … Read more
In Depth Sauropelta is one of the better known nodosaurids, armoured dinosaurs that are thought to be ancestral to the later and more heavily armoured ankylosaurids. This armour was in the form of lots of osteoderms (bony plates that are held within the skin that are also sometimes called scutes) that varied greatly in size … Read more
In Depth Siamraptor is a genus of carcharodontosaurid dinosaur that lived in Asia during the early Cretaceous. The holotype individual of Siamraptor is only known from a partial skull, jawbone and a few post cranial bones, so precise details or any unusual features if they existed, are still unknown. These scattered bones however do indicate … Read more
In Depth In simple terms Eucnemesaurus was a prosauropod, a member of the group that was ancestral to the later larger sauropods. Eucnemesaurus has a better know association with a former dinosaur genus Aliwalia. Aliwalia was big news when described, even though it was only described from a femur and a partial maxilla. The maxilla … Read more
In Depth Noted for its similarity to the genus Tapejara, Caiuajara is a tapejarid pterosaur that lived in South America during the late Cretaceous. Tapejarid pterosaurs are noted for their large head crests, and Caiuajara is no exception. The crest of Caiuajara has been reconstructed to have formed a crest shaped much like a shark … Read more
In Depth Eurhinosaurus is one member of what still appears to be a small group of ichthyosaurs that had specialised asymmetrical jaws. What this means in more detail is that the rostrum of the upper jaw extended beyond the lower jaw to give Eurhinosaurus a head and set of jaws that resemble a modern day … Read more
In Depth Living in the late Cretaceous, Gilchristosuchus was a crocodile that in evolutionary terms may have come close to modern crocodiles, yet may not have actually been one of them. The size of Gilchristosuchus is still unknown but the one partial skull known shows signs of fusing, indicating that it was an adult specimen. … Read more
In Depth Due to the incomplete remains not a lot is known about this dinosaur other than it is probably a basal titanosauriform. The genus name is a reference to the appearance of the tail vertebrae while the species name of R. cooneyi is in honour of J. P. Cooney who owned the land where … Read more
In Depth Heptasuchus is a genus of fairly large rauiscuhian that lived in what is now Wyoming during the mid/early late Triassic. Rauisuchians were the top predators on land and held onto this title until the appearance of large theropod dinosaurs. Out of these Heptasuchus is usually considered to be most similar to Batrachotomus from … Read more
In Depth The name Tsagantegia means ‘of Tsagen-Teg’ which can be further translated to Englishto mean ‘of White Mountain’, and this is a reference to the location where the holotype skull of Tsagantegia was first discovered. Tsagantegia is currently represented by a single skull, the features of which clearly identify Tsagantegia as an ankylosaurid dinosaur. … Read more
