In Depth Phonodus has been described as a genus of procolophonid that lived in South Africa during the earliest part of the Permian. With Phonodus being the fifth such genus from this time and location, this suggests that the procolophonids survived fairly well during the extinction that signalled the end of the Permian.

In Depth Brodavis was a genus of hesperornithiform that lived in both Asia and North America towards the end of the Cretaceous. Like relative genera, Brodavis would have dived below the water and used well developed feet to swim through the water after fish.

In Depth There is a lot of mystery surrounding Iliosuchus as the genus is only based upon the description of three ilia. These parts are not diagnostic enough to clearly identify what kind of theropod dinosaur Iliosuchus was, though in England during the Mid Jurassic the dominant theropod dinosaurs were the megalosaurs.

In Depth Not a lot is known about Qingxiusaurus beyond that the type fossils seem to have come from a titanosaur. Only a few bones of the anterior skeleton and fore limbs are known, making a total size of the dinosaur difficult to establish with certainty. In addition to this the location of the fossil … Read more
