The world at the start of the Cisuralian

The Cisuralian is the first series/epoch of the Permian.

Biodiversity[change | change source]

The Cisuralian was full of many animals such as actinopterygian Amblypterus and prototherapsid Tetraceratops. The swampy fringes were mostly ferns, seed ferns, and lycophytes.

An unusual shark called Helicoprion also made its appearance. This strange fish had a tooth whorl.
