The Permain Period

The permain animals were fasinating. At the end of the period there was a mass extintion wiping out 90% of ocean life! There were many animals like Dimetrodon, Gorgonopsia, Inostrancevia, Edaphosauridae, and many more. Several animals appeared at the time like palaeodictyopterans and pelycosaurs.But as I said near the end of the period lots of life went extict. Some include Dimetrodon. But thats the way life goes some things will die.
