Jul 8, 2022 · A third abundant group of fossils in the Permian reef is echinoderms, such as crinoids (sea lilies) and echinoids (sea urchins). Echinoderms are solitary, bottom- dwelling, marine organisms. An endoskeleton with bilateral symmetry, which is formed of plates or ossicles composed of crystalline calcite, characterizes these organisms.

The Permian Period, spanning the 43 Ma interval between 294 Ma and 251 Ma, witnessed several major turning points in Earth's history. Pangaea, the greatest supercontinent of all time, finally amalgamated in the Permian, and began to break up again almost immediately in a prolonged disintegration that would finally finish in the Cretaceous.
