Eurypterids, or "Sea Scorpions" are an order of ancient arthropods that lived in the Paleozoic era. These formidable Paleozoic predators appeared in the Ordovician and became extinct in the great Permian mass extinction. They seem to have reached their peak in the Silurian. Eurypterids are not Crustaceans. Fields. The Permian Basin is a large sedimentary basin in the southwestern part of the United States. It is the highest producing oil field in the United States, producing an average of 4.2 million barrels of crude oil per day in 2019. This sedimentary basin is located in western Texas and southeastern New Mexico. These Permian deposits include the red beds of south-central Kansas. The sand and silt were washed down from the distant mountains and deposited along the shores of the retreating Permian sea. The red beds have gypsum, salt, and dolomite interbedded with them. Permian Shale and Gypsum in Barber County. The sea surface temperatures in the Sea of Japan are partly controlled by the Tsushima warm current, which enters via the Tsushima Strait and exits mostly at the Tsugara Strait, and partly by the Liman/Korean cold currents, which flow along the Primorye and Korean coasts.The Permian Basin was an inland sea connected to the vast ocean surrounding Pangea by a narrow channel with three main arms: the Marfa, Delaware, and Midland Basins.
