In Depth Sahaliyania was discovered and described along with another new hadrosaurid dinosaur called Wulagasaurus, however this one appears to have been a saurolophine hadrosaurid, whereas Sahaliyania is more clearly defined as a lambeosaurine hadrosaurid. Initially based upon the description of a partial skull, further fossil remains have since been attributed to Sahaliyania. Aside from … Read more
In Depth Shri is a genus of dromaeosaurid dinosaur that lived in Asia during the late Cretaceous. The holotype specimen of Shri was originally thought to belong to the Velociraptor genus, but later study has revealed that the fourth trochanter (a bulbous bone growth near the hip joint of the femur that served as a … Read more
In Depth Notocolossus seems to be yet another genus of giant titanosaurian sauropod dinosaur from South America, a continent that is now famous for the presence of such dinosaurs. The full length of Notocolossus is still speculative, but with an upper arm bone measuring 1.76 meters in length, it is fairly safe to say that … Read more
In Depth Unfortunately not only are pterosaur fossils rare in Australia they are usually very fragmentary; such is the case for Aussiedraco. The type specimen had been known for over thirty years before it was granted the name Aussiedraco and represents the front piece of the lower jaw. The jaw itself was thin like you … Read more
In Depth At the time of its description only known from a partial skull, Zaraapelta is a genus of ankylosaur that lived during the late Cretaceous. The Zaraapelta holotype skull was found in the Barun Goyot Formation of Mongolia, indicating that Zaraapelta shared the same ecosystem as two other ankylosaurid genera called Tarchia and Saichania. … Read more
In Depth Arackar is a genus of titanosaur that lived in South America during the late Cretaceous. Though only known from partial remains, Arackar was at the time of its description one of the most complete individual dinosaurs discovered in Chile. Further reading - Arackar licanantay gen. et sp. nov. a new lithostrotian (Dinosauria, Sauropoda) … Read more
In Depth Like in other ornithocherid pterosaurs the sharp teeth of Boreopterus project out to the sides with the largest near the tip of the snout, most notably the third and fourth pairs from the tip of the snout. When the teeth near the tips of the jaws meshed together they made for an effective … Read more
In Depth Potentially, Aetosauroides is one of the oldest aetosaurs currently known, and is comparable in age to other genera such as Stagonolepis and Aetobarbakinoides. In fact Aetosauroides has been suggested to be a synonym to Stagonolepis on more than one occasion, though the wider consensus is that it is actually a separate genus. As … Read more
In Depth Fossils of Citipes were first described in 1933, but as a species of Ornithomimus. After this they subsequently moved into the Elmisaurus and Leptorhynchos genera respectively, before finally being described as a distinct genus in 2020. Citipes is a genus of oviraptosaur dinosaur that lived in North America during the late Cretaceous. Further … Read more
In Depth With a name that translates to English as ‘Monstrous murderer’, Teratophoneus has arguably one of the most apt names of any dinosaur, although the remains suggest that it was smaller than many of the other tyrannosaurids. The species name, T.curriei, is in honour of palaeontologist Philip J. Currie. Teratophoneus was a very interesting … Read more
