Bolbometopon

Bolbometopon is a genus of extinct marine reptiles that lived during the Late Triassic period, approximately 230 million years ago. The genus is known from a single species, Bolbometopon laticeps, which was discovered in the United Kingdom. Bolbometopon is notable for its distinctive skull structure, which features a large, rounded skull cap that gives the genus its name, derived from the Greek words "bolbe" meaning "round" and "metopon" meaning "forehead."

The skull of Bolbometopon is characterized by a large, domed occipital region, which is unique among marine reptiles. This structure is thought to have been used for sensory or communication purposes, although its exact function remains uncertain. The genus also possesses a long, narrow snout and a series of small, tooth-like structures on the roof of its mouth, which are believed to have been used for sensing water currents.

Bolbometopon is classified within the order Thalattosauria, which includes other extinct marine reptiles such as ichthyosaurs and plesiosaurs. However, unlike these groups, Bolbometopon is not known to have possessed any form of flippers or limbs, suggesting that it may have been a more primitive marine reptile.

The fossil remains of Bolbometopon have provided valuable insights into the evolution of marine reptiles and their adaptations to aquatic environments. However, due to the limited number of fossils discovered, much about the biology and behavior of Bolbometopon remains unknown. Further research and the discovery of additional fossils may help to shed more light on this intriguing genus.
