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. In addition, we find a coupled phase relationship between high sea levels and eccentricity maxima, suggesting that eccentricity may have played a critical role in the early Permian sea-level oscillations. Paleoclimate simulations show that eccentricity and obliquity maxima lead to an overall increase in global mean temperature.I assume you are referring to the Exxon sea level curve shown here which indicates a relatively low sea level at the Permian Triassic boundary around 250 ... ….
