Description: | Specimen of a fossil brachiopod (lamp shell), Spirifer trigonalis, collected from the Carboniferous Limestone of Early Carboniferous, Dinantian, Visean, Asbian age from Northumberland (NE England). Collected by Sir W.C. Trevelyan.
Spirifer is a common Carboniferous brachiopod (lamp shell) that is easily recognised by its long, straight hinge line (the junction between the two shells at the hinge where the shells meet). The original shells have been dissolved away leaving a cast of the insides. This group might have been a colony of living brachiopods or a collection of drifted, dead shells. Spirifer lived attached to the floor of a warm, shallow, tropical sea and fed on small particles of food that it filtered out of the water.
The specimen was found in Northumberland.
It is from the Carboniferous period (362 - 290 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Brachiopoda Invertebrata Sir Trevelyan Articulata W.C. | Temporal: | Carboniferous period (362 - 290 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
