Palaeocarcharias

Palaeocarcharias is an extinct genus of mackerel shark that lived during the Eocene epoch. Its fossil remains have been found in various locations around the world, including Europe and North America. The genus is known from teeth, which are relatively small and slender, with a smooth surface. These teeth are diagnostic and help paleontologists identify Palaeocarcharias fossils.

The shark itself is thought to have been a relatively small to medium-sized predator, likely preying on fish and other small marine animals. Its taxonomic placement has been debated, but it is generally considered to be within the order Lamniformes, which also includes modern sharks like the great white and mako sharks. The discovery of Palaeocarcharias provides valuable insights into the diversity of sharks during the Eocene, a period of significant marine ecosystem change. Studying its morphology and distribution helps researchers understand the evolutionary history and paleoecology of ancient shark communities.
