In Northeast Asia there were two main bivalve paleocommunities, shallow and deep sea bivalves. Through the Permian, the bivalves began to dominate benthic assemblages. There are five major stages ...The sudden transition from a cool-water, heterozoan dominated carbonate ramp to a warm-water, metazoan-free, homoclinal carbonate ramp following the Permian-Triassic mass extinction was the result of the combination of the loss of metazoan reef/mound builders, rapid sea-level changes across Permian-Triassic mass extinction and profound global …Alfred Wegener c. 1924–1930.

Some groups went extinct, while a few species in other groups made it through. Sea urchins, once diverse during the Permian, were devastated—only one species survived. Ammonites, too, were hard hit. A new-found Permian-Triassic boundary section in Xiushui, Jiangxi Province, China shows evidence for sea-level drop during the latest Permian. Evidence for sea-level drop was preserved in a 2.1 m ...A number of classic studies have been completed on the "Permian reef complex" of New Mexico and Texas which have established an excellent stratigraphic and sedimentologic framework for the region.

Heuvelmans also considered and rejected a sea scorpion identity for the many-finned sea serpent type. Shuker agrees with his rejection, and considers the existence of post-Permian sea scorpions unlikely, given the lack of evidence.Permian Period, in geologic time, the last period of the Paleozoic Era, lasting from 298.9 million to 252.2 million years ago. The climate was warming throughout Permian times, and, by the end of the period, hot and dry conditions were so extensive that they caused a crisis in Permian marine and terrestrial life.This layer has been deposited from the Permian Sea as the first carbonate beds, containing abundant macrofossils, such as crinoids, corals, bryozoan, and gastropods with sand and silt grains and sandstone beds near the base. ...

Overlying the Glorieta Sandstone in the park are limestones, minor dolomites, shales, siltstones, and gypsum of the Permian San Andres Formation. The upper San Andres limestone beds locally contain fossils (Smith, 1954). The San Andres Formation was deposited along the bottom of the shallow epicontinental Permian sea.Texas has the geographic advantage of the Permian Basin with oil fields.
