Description: | Specimen of a fossil bivalve, Aequipecten aspera, collected from the Inflatum Zone = Dispar Zone, Upper Greensand Formation of Early Cretaceous, Late Albian age from Warminster, Wiltshire (SW England).
This round bivalve shell has prominent 'ears' next to the hinge line (the area where the two shells (valves) meet at the back) and three-fold ribs. The scallop lived on sandy seabeds in shallow coastal waters. It was able to swim short distances by clapping the valves together. A ligament on the hinge allowed the shells to open at an angle of up to 30° whilst feeding. The bivalve fed on tiny food particles that it filtered out of sea water.
The specimen was found in Wiltshire.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Invertebrata Bivalvia Mollusca | Temporal: | Cretaceous period (144 - 65 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
