Description: | Specimen of a fossil brachiopod (lamp shell), Leptagonia analoga, collected from the Carboniferous Limestone of Early (?) Carboniferous age. Shows brachial structure.
This brachiopod (lamp shell) has a very distinctive rectangular shaped shell with a straight hinge line (the line between the two shells at the hinge). One shell is convex (outward curving), the other concave (inward curving) and both have an angular fold near the edge. Leptagonia lay on sea floor with the convex shell facing downwards. It is often found in the shallowest waters of reef communities. Like all brachiopods it fed on food particles that it filtered out of the water.
It is from the Carboniferous period (362 - 290 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Brachiopoda Invertebrata | Temporal: | Carboniferous period (362 - 290 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
