Description: | Specimen of a fossil bivalve, Grammysia sp., collected from the Dufton Shale Formation, Corona Beds, Roman Fell Group of Late Ordovician, Caradoc, Longvillian age from Roman Fell, Dufton, Cumbria (NW England).
Bivalves, which are very common shellfish on the sea shore at the present day, were much rarer in the Ordovician period. This specimen would have lived in the mud on the seabed. Brachiopods (lamp shells) were much more common in the Ordovician seas but very few brachiopods have survived to the present day.
The specimen was found in Cumbria.
It is from the Ordovician period (495 - 443 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Invertebrata Bivalvia Mollusca | Temporal: | Ordovician period (495 - 443 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
