Description: | Brachiopods are animals which live in or on the seabed. Although fairly rare in present day seas, their fossilised shells are very common in Silurian rocks and show an amazing variety of different shapes. The animal was protected by two shells hinged at the pointed end. Sometimes, as in this example, the two shells are very different in shape and form. This view of the back of the two shells shows a top shell which is fairly flat but the lower shell has much more of a triangular shape. Such a curious difference of shape suggests a specialised way of life which we can only guess at as this kind of brachiopod became extinct millions of years ago. | 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 |
