👉 Prochilodontidae are a group of extinct, highly specialized fish that lived during the Late Cretaceous period in Europe and North Africa. These fish were characterized by their long, slender bodies and large eyes that allowed them to see through water, allowing them to hunt for prey such as insects and crustaceans. They also had a unique system of teeth known as the prochilodont tooth pattern, which was adapted to their fast swimming speeds and sharp teeth.
