pericentrum

Pericentrum is a genus of extinct pliosaurid ichthyosaurs that lived during the Early Triassic period. The name "Pericentrum" was coined by Albert-Félix de Lapparent in 1960. Pericentrum is known from a large number of fossils found in the Early Triassic deposits in France.

Fossil evidence suggests that Pericentrum was a large predator, measuring up to 3 meters in length. The genus is characterized by its long, slender body, with a large head and a long, pointed snout. The skull is distinct from that of other pliosaurids due to its extending rostrum, which is characterized by a series of ridges and tubercles.

Pericentrum was a highly specialized predator that likely preyed upon other marine animals. Its diet probably consisted of fish, squid, and other cephalopods. The jaws of Pericentrum were not suited for grasping prey, but rather for catching and devouring large prey whole.

Pericentrum lived during the Middle to Late Triassic, a time period when the oceans were significantly warmer than they are today. This is evident from the presence of stratigraphic deposits of caliche and evaporative salt, which indicate a shallow and warm marine environment.

The genus is significant to the scientific community due to its unique characteristics and its position within the family Plesiosauria. Its discovery has shed light on the evolution of pliosaurids and their eventual extinction. In addition, the research on Pericentrum has expanded our understanding of early marine reptiles and their role in the ocean's ecosystem during the Triassic period.
