Description: | This tooth is from an early bony fish that grew to a length of 6 or 7 metres. It belonged to a group of fishes with lobe-shaped fins that also included the coelacanths. Rhizodus had two large fang-like teeth (tusks) at the front of the jaw that grew up to 22cm in length. The strong, pointed teeth were ideal for hunting prey of smaller fish and amphibians in the freshwater rivers and lakes where the fish lived. | 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 |
