Belemnites: Key Players in Evolution

Belemnites: Key Players in Evolution

Belemnites were a group of extinct cephalopods that lived during the Mesozoic era, around 200 to 65 million years ago. These creatures were closely related to modern squids and cuttlefish, having a long, cone-shaped shell called a guard that helped them float in the water.

Belemnites played a crucial role in the evolution of marine ecosystems during their time, serving as important predators and prey. Their fossils have been found all over the world, providing valuable insights into the biodiversity and environmental conditions of the past. Scientists study belemnites to better understand the history of life on Earth and how it has changed over millions of years.
