Description: Ichthyosaur extinct dinosaur age aquatic reptile bone fossil. This fossil is from Isle of Wight, United Kingdom. This bone piece is about 2 1/2" x about 1". I'm unsure which part of the Ichthyosaur this fossil is from. The fossil comes in an Ichthyosaur display case that you will find nowhere else and includes a laminated information card. All fossils sold are authentic, no replicas. Ichthyosaur Ichthyosaur, any member of an extinct group of aquatic reptiles, most of which were very similar to porpoises in appearance and habits. These distant relatives of lizards and snakes were the most highly specialized aquatic reptiles, but ichthyosaurs were not dinosaurs. Ichthyosaurs had a very wide geographic distribution, and their fossil remains span almost the entire Mesozoic Era (251 million to 65.5 million years ago); but they were most abundant and diverse during the Triassic and Jurassic periods (251 million to 145.5 million years ago). Ichthyosaurus, a representative genus from which the larger group takes its name, was about 10 feet long and was probably able to move through the water at high speeds. Very fishlike in appearance, it is especially well known from Early Jurassic deposits in England. The body was streamlined; no distinct neck was present, and the head blended smoothly into the body. The limbs were modified into paddlelike appendages used to steer the animal. It propelled itself by using a well-developed fishlike tail and by undulating the body. The skull and jaws of Ichthyosaurus were long and contained numerous sharp teeth. The eyes were very large, a trait some scientists believe gave these reptiles the ability to discern large shapes, such as those of the pliosaurs, at long distances. (Pliosaurs were large carnivorous marine reptiles thought to prey on ichthyosaurs.) They probably fed largely upon fish as well as other marine animals. It is unlikely that they ventured onto land, and they certainly reproduced in the water. If stranded ashore, they would have been as helpless as beached whales. Ichthyosaurs persisted into Late Cretaceous times and may have been well adapted for deep diving as well as near-shore predation, but all species became extinct well before the end of the Cretaceous Period.
