A couple things:
The land plans and animals were somewhat homogenous during pangea time.
Ocean ecosystems run the globe, and these are mainly found in shallow waters. When there is a supercontinent, the amount of shallow water is reduced, so diversity and abundance decreases globally. Along with the Permian ice age, there is lower diversity and abundance until the Triassic-Jurassic when rifting of Pangea creates new shallow oceans.

Pangea formed and remained intact from the Permian to Early Jurassic. Your question is very broad and vague. Could you be more specific in what information you are seeking?
