Diplo Caulus
Deep Caulos is a genus of ancient amphibians belonging to the Gongchu River that flourished in the Permian period. The shape of the body is similar to that of a salamander, but its size is relatively large and it has grown to a few meters. It is also known as a long protrusion similar to a boomerang on either side of the skull. With a weak leg and a relatively short tail, it is assumed that De Paolo Coulos would swim up and down, with wide left and right heads helping to glide through the water like the caudal fin of a modern whale . Also, this head shape may have been used to protect the body from predators such as Erios, because it is very difficult to swallow such a wide head. A close relative of Diplo Kaurus is Diplo Raspeis.
