duplextulostus
Duplextulostus 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, Duplextulostus longus, which was discovered in the United States. Duplextulostus is notable for its unique and distinctive features, including a long, slender body, a large head with a distinctive snout, and a set of sharp teeth. The reptile is believed to have been a semi-aquatic predator, using its long body and sharp teeth to hunt for fish and other small aquatic animals. The genus is named for its distinctive feature of having two rows of teeth in the upper jaw, which is a unique characteristic among marine reptiles. Duplextulostus is an important fossil find that provides valuable insights into the evolution of marine reptiles and their adaptations to aquatic environments.
