Description: | This brachiopod (lamp shell) has a smooth biconvex shape (both shells are outward curving). It has a clear ridge and hollow on the junction between the two shells. Like most brachiopods Martinia was attached to the sea floor by a pedicle (fleshy stalk) that grew through a hole on the fold of the larger shell close to the hinge line (where the shells are attached to each other when they are open). It lived on the muddy floors of warm, shallow tropical seas and fed on food particles that it filtered out of the water. | 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 |
