In Depth Although neither a nothosaur nor a plesiosaur, Pistosaurus appears to be closely related to both. Pistosaurus had both a stiffened spine and limbs adapted into flippers, but still retained a palate like a nothosaur and for this reason Pistosaurus is often considered an evolutionary offshoot of a type that appeared alongside plesiosaurs while … Read more
In Depth Wangosaurus is a genus of pistosaurs that lived in the waters around what is now China during the Triassic. Pistosaurs like Wangosaurus were the precursors to the plesiosaurs that would rise to prominence by the end of the Triassic, and go on to live in the worlds ‘oceans throughout the Mesozoic.

In Depth Originally described as a nothosaur, Corosaurus is now identified as a pistosaurid, a kind of sauropterygian reptile that is related to but separate to the true nothosaurs. The pistosauroids are established around the type genus pistosaurus, and it may have been these kinds of marine reptiles that were actually ancestral to the plesiosaurs … Read more
In Depth Cymatosaurus is usually seen to be a member of the Pistosauridea. This group of marine reptiles were the forerunners of the plesiosaurs which seem to have evolved from later more advanced pistosauroid forms. Other members of this group include Augustasaurus and Pistosaurus, but Cymatosaurus probably also shared the ocean with placodonts like Placodus, … Read more
In Depth Augustasaurus was the second member of the Pistosauroidea group of Triassic marine reptiles discovered. Given that the first (and currently only other of known) member of the group, Pistosaurus, is known from Europe, this reveals that the pistosauroid sauropterygians had at least a reasonable geographic range. Like with Pistosaurus, Augustasaurus resembles early plesiosaur … Read more
