In Depth With a tough hide and powerful jaws, the rauisuchian genus Postosuchus was one of the apex predators of its time. First discovered in the US state of Texas, Postsuchus had a wide distribution that stretched all the way to the Eastern seaboard. The head was deep with many fenestrae, adaptations that point towards … Read more
In Depth Taking up half of its total body length, Tanystropheus’s neck is almost inconceivable. Indeed, when Francesco Bassani discovered Tanystropheus remains in 1886 (although he named it Tribelesodon), he conceived the extra long neck vertebrae as the wing bones of a pterosaur. It was not until later that the mistake was realised and Tribelesodon … Read more
In Depth Collilongus is a genus of archosauriform that lived in Poland during the Triassic. Little is known about Collilongus because so far the genus is only known from teeth.

In Depth Even though it was ten meters long, it is not its size that makes Stomatosuchus stand out but its presumed feeding strategy. The upper jaw only had small conical teeth, while the lower jaw has been suggested at being toothless, with the inclusion of a pelican like pouch underneath. This is unprecedented amongst … Read more
In Depth Temnodontosaurus is one of the oldest and largest ichthyosaurs known to science, and while there are a few species associated with the genus, the most obvious differences between these are the size and proportions of the jaws. Temnodontosaurus fossils have been so well preserved that they reveal stomach contents of ammonites and cephalopods … Read more
In Depth Lazarussuchus was named after the figure of Lazarus of Bethany in the Bible, a person in the Gospel of John who was resurrected four days after his death by Jesus Christ. The relevance here is that the holotype remains of Lazarussuchus were found from a late Oligocene deposit, a period many millions of … Read more
In Depth Garjainia is a close relative of the more famous Erythrosuchus, and like that genus, Garjainia also had what appeared to be an oversized head. This head, filled with numerous sharp teeth would have been the primary killing weapon against the herbivorous animals of the time. Further Reading - A New Species of Garjainia … Read more
In Depth Yonghesuchus is a genus of small arhcosaur that lived in China during the Triassic. Although a total body length is unknown at the time of writing, the small skull size alone indicates that Yonghesuchus would have been a small animal, and a predator of animals even smaller than itself.
