Where did the ichthyosaurs live in the world?

Ichthyosaurs primarily inhabited the oceans during the Mesozoic Era, particularly from the Triassic to the Cretaceous periods. Fossil evidence has been found in various parts of the world, including Europe, North America, and Asia, indicating that they thrived in both shallow and deep marine environments. These marine reptiles were well-adapted to life in the water, making them widespread across ancient seas.
