This is Rhinesuchus, a giant amphibian labyrinthodont.
— Allen, about Rhinesuchus

Rhinesuchus (name meaning "Crocodile Nose") is a genus of labyrinthodont amphibian that originated during the Late Permian Era in what is now South Africa, Siberia, and Germany. Measuring over two meters long, this was a giant, prehistoric amphibious predator.

In the Series 1 episode "Desert Community Water Hole", a single female Rhinesuchus was brought back to the park from Siberia 250 million years ago.


Era & DiscoveryEdit

Rhinesuchus lived during the Late Permian period 260-248 million years ago. It was first discovered in 1908.

Physical AttributesEdit

Rhinesuchus was a large amphibian, over 6–8 feet (2–2.5 m) long. It had short, splayed out legs with three digits on the forelimbs and five on the hind limbs. It had thin skin covered in wart-like bumps. It was brown with dark brown spots and warts.

Behavior & TraitsEdit

Being a giant amphibian, Rhinesuchus lived in rivers, ponds, lakes and even in the seas and depended heavily on water, as other amphibians do, and could live with several others of their kind. When hunting, Rhinesuchus laid n ambush underwater as a crocodile does. If the lack of inland water left it stranded from lakes and even the seas, they would make refuse in small water holes. Because of this, it was under threat by predators and the water drying out. If one of the two happens, there was zero chance that Rhinesuchus would survive.

The amphibian did, however, have one adaptation that was used as a last resort. Before their water environment could dry up, these giant amphibians burrowed into the damp mud and they would form a cocoon around themselves in a last-ditch attempt to try and sit out the drought conditions. However, if they were ever found in their torpid state by predators like Inostrancevia, it would be an easy, helpless target for predators. However, the chance that Rhinesuchus would survive in that state was extremely slim.
