dictyosaurs

Dictyosaurs, also known as Dictyosauroids, are a group of extinct marine reptiles that lived during the Late Triassic and Early Jurassic periods, approximately 237 to 183 million years ago. They are characterized by their distinctive, paddle-like limbs and a long, slender body, which allowed them to swim efficiently. Dictyosaurs are believed to have been semi-aquatic, spending most of their time in the water but occasionally venturing onto land.

The most well-known dictyosaur is the ichthyosaur, which is often confused with the plesiosaur. Ichthyosaurs had a more streamlined body and were fully aquatic, while plesiosaurs had shorter, more robust limbs and were semi-aquatic. Other notable dictyosaurs include the pliosaur, which had a more robust build and was capable of hunting large marine animals.

Dictyosaurs are thought to have been important predators in their ecosystems, feeding on a variety of marine creatures. Their fossils have been found in various parts of the world, including Europe, North America, and Africa. The study of dictyosaurs provides valuable insights into the evolution of marine reptiles and their role in ancient marine ecosystems.
