Plesiosaurus: Anatomy, Habitat, and Fossil Evidence of the Ancient Marine Reptile #1461736 (License: Personal Use)

This black-and-white anatomical drawing depicts Plesiosaurus dolichodeirus, a genus of plesiosaur that thrived during the Early Jurassic epoch (~199-185 million years ago). The illustration highlights its distinctive features: a streamlined body, relatively short tail, four robust flippers used for propulsion, and a narrow, tooth-filled jaw adapted for catching fish and cephalopods. Such reconstructions are based on well-preserved fossils found primarily in Europe, especially England’s Lyme Regis.
