Description: | The fossil shell embedded in this rock is of a brachiopod (lamp shell). The animal which made the shell lived attached to the bottom of the sea. It fed on food particles it was able to filter out of the water. The original shell, made of calcium carbonate, has dissolved away and only the imprint of the inside of the shell (a mould) remains. Because the shell has not survived, it is sometimes very hard for geologists (scientists who study rocks and fossils), to identify it. | 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 |
