Description: | Teeth are often the only parts of reptiles that are preserved as fossils. These pointed teeth have grooves and ridges that show they are from an Ichthyosaur. Ichthyosaurs grew up to 3m long and looked like dolphins with a long snout. However, unlike dolphins which have a horizontal tail, Ichthyosaurs had a vertical tail. They were predators and scavengers that fed mainly on fish, ammonites and belemnites. They were well adapted to life in the sea and are thought to have given birth to living young (most reptiles lay eggs on land). | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
