Description: | Specimen of a fossil brachiopod (lamp shell), Productus senbaculus, collected from the Redesdale Ironstone, Scremerston Coal Group of Early Carboniferous, Dinantian, Visean, Asbian age from Northumberland (NE England). Collected by Sir W.C. Trevelyan.
The shells (valves) of Productus are quite different in size and shape. The larger convex (outward curving) shell rested on the sea floor and a smaller flat shell acted like a lid. Productus was an unusual brachiopod because it did not have a pedicle (fleshy stalk) to keep it fixed to the sea floor. Instead it used stubby spines on the outside of the concave shell to keep it in position. The broken ends of these spines can be seen clearly on one specimen
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 |
