Walking with Dinosaurs: Koskinonodon

Koskinonodon perfecta
Named by E. B. Branson and M. G. Mehl, 1929
Diet: Carnivore/Piscivore
Type: Stereospondyl trematosaur temnospondyl amphibian (metoposaur)
Size: 10 feet (3 meters) long and 200 lb.
Region: North America (Arizona USA)
Age: Late Triassic (228 to 216 million BC; Carnian to Norian)
Enemies/Rivals: Phytosaurs such as Leptosuchus and Smilosuchus.
Episode: New Blood (only in the book Walking with Dinosaurs: A Natural History) (Identified as metoposaur)
Info: A member of a family of slab-headed, stereospondyl trematosaur amphibians known as the metoposaurs that were diverse in the Mid to Late Triassic in North America, Europe, India, and Africa, the 10-foot (3-metre) long Koskinonodon prowls through the muddy beds of the waterways in what is now the Southwestern United States during the Late Triassic period, preying on fish with a mouth full sharp teeth. The stereospondyls were the last of the ancient large temnospondyl amphibians that were once the dominant predators in the waterways since the Carboniferous period and narrowly  survived the catastrophic Permian-Triassic Mass Extinction Event (which killed off most of them), but had faded into oblivion in the Triassic as reptilian predators that were taking over and replaced them and while many of them (including the metoposaurs) died out during the Triassic-Jurassic Mass Extinction event, 201.3 million years ago, only a few families of them survived and remained right up until the Mid Cretaceous.

Note: Based on the display skeleton from the American Museum of Natural History, New York. If you are wondering, no it didn't appear in the original series, but it did appear as a background animal in the New Blood chapter in the book Walking with Dinosaurs: A Natural History and was identified as metoposaur. I changed it to Koskinonodon for the fact that it was common in the Chinle Formation and Metoposaurus itself now lives in Europe. So yeah I am going to do the background animals that only appear in the companion book of the original series, such as the phytosaurs and Coelurus. Also I posted this yesterday, but I deleted it, because it was too short and less detailed.
