teleosauroid

Teleosauroidea is an extinct superfamily of teleosaurid crocodylomorphs, a group of semi-aquatic reptiles that lived during the Jurassic and Cretaceous periods. These ancient crocodiles were characterized by their long, slender snouts and well-developed teeth, suggesting a predatory lifestyle focused on fish and other aquatic prey. Teleosauroids were widespread, with fossils found across Europe, Africa, and Asia, indicating a significant presence in marine and coastal environments of the time.

The superfamily includes several notable genera, such as Teleosaurus, Steneosaurus, and Mystriosaurus. Teleosaurus, often considered the type genus, is known from the Middle Jurassic of Europe and is characterized by its extremely elongated snout. Steneosaurus, also from the Jurassic, possessed a similar build but with some distinct cranial features. Mystriosaurus, found in the Early Cretaceous of Europe, represents a later evolutionary development within the group.

Teleosauroids were an important component of Mesozoic marine ecosystems. Their morphology suggests they were powerful swimmers, capable of hunting in open water. Their extinction, along with many other marine reptiles, occurred by the end of the Cretaceous period, likely due to environmental changes and competition from other predators. The study of teleosauroids provides valuable insights into the diversity and evolution of crocodylomorphs and the paleoecology of ancient marine environments.
