Belemnites: Cephalopods of the Mesozoic Era

Belemnites were a group of extinct cephalopods that lived during the Mesozoic Era, from the Triassic to the Cretaceous Periods. These creatures were closely related to modern squids and cuttlefish, with a long, bullet-shaped shell called a guard that served as a buoyancy aid.

Belemnites were efficient predators, using their tentacles to catch small fish and other prey. They had a well-developed brain and complex eyes, making them skilled hunters in the ancient seas. Their fossils are found all over the world, providing valuable insights into the evolution and diversity of cephalopods during the Mesozoic Era.
