Description: | Specimen of a fossil brachiopod (lamp shell), Leptagonia sp., collected from the Carboniferous Limestone of Carboniferous age. Assemblage forming most of rock.
One shell of this brachiopod (lamp shell) is convex, the other concave (inward curving) and both have a distinctive angular fold near the margin. Leptagonia lay on sea floor with the convex shell facing downwards. It is often found in the shallowest waters of reef communities. It is not clear whether the shells in the specimen were a colony of living brachiopods or a collection of drifted dead shells. 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 |
