In Depth As with other Australian sauropods such as Wintonotitan and Diamantinasaurus, the skull and most of the vertebrae are unknown. What can be learned from the available material is that Austrosaurus had a fairly level back between its shoulders and hips with what appears to be only twenty centimetres height difference between the two. … Read more
In Depth It is hard to currently establish a size estimate for Arcusaurus because at the time of writing the genus is only represented by the partial remains of two juveniles. Not only does this make it impossible to run a tape measure along a known complete specimen, but as juvenile they would have grown … Read more

In Depth Zalmoxes was discovered when fossils that had been assigned to the genus Rhabdodon as R. robustus (originally robustum) were discovered to have different distinguishing features. This was actually the second time that the material had been re-named as initially it was known as a species of Mochlodon. Today Zalmoxes is described as an … Read more
In Depth Aviatyrannis was for lack of a better word tiny, although this small size is actually a hallmark of tyrannosaur ancestry. Although incomplete, the fossil remains of Aviatyrannis are very similar to another ancient tyrannosaur, Stokesosaurus, from North America. This has resulted in speculation that Aviatyrannis is actually a junior synonym of Stokesosaurus, and … Read more
In Depth The discovery of Attenborosaurus was unorthodox to say the least. When first discovered the remains were referred to the Plesiosaurus genus as a new species, P. conybeari. These remains were destroyed during a bombing raid in World War II, but a plaster cast of them was made before this happened which has meant … Read more
In Depth Described in 2016 on the basis of two skulls and jaws, Agaresuchus fontisensis was a crocodile that lived in Spain during the late Cretaceous. Additionally a second species originally named as a species of Allodaposuchus, A. subjuniperus was also re-described as belonging to the genus in 2016.

In Depth A passing glance at the dinosaur Bajadasaurus would likely bring immediate comparisons to another very popular sauropod dinosaur known as Amargasaurus. Amargasaurus made headlines when it was named because of the large spines that rose out and back from the neck, at the time making it unique amongst sauropod dinosaurs. The discovery of … Read more
In Depth Aepyornithomimus is a genus of ornithomimosaurid dinosaur that lived in Asia during the late Cretaceous.

In Depth Originally named as a species of Doswellia, Rugarhynchos is a genus of proterochampsian archosauromorph that lived in North America during the late Triassic. Rugarhynchos is noted for the shortness of its snout when compared to other doswelliids.
