Description: | Teeth often provide the only evidence of fish such as sharks because they have skeletons made out of cartilage which usually rots away and does not preserve. This tooth is from a medium sized shark. Its living relatives grow to between 2 and 3 metres in length and include the porbeagle and mackerel sharks which live in temperate (cool) oceans and coastal waters. They are predators and feed mainly on fish such as herring and mackerel as well as bottom-living flat fishes. | 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 |
