Description: | Specimen of a fossil bivalve, Exogyra latissima, collected from the Stenomphalus Zone = Inflatum Zone, Speeton Clay Formation of Early Cretaceous, Late Ryazanian - Albian age from Speeton, North Yorkshire (NE England).
This is only half of the oyster and is the larger, convex (outward curving) shell that rested on the sea floor. The other shell was flat and opened like a lid. Like present day oysters, Exogyra lived in shallow coastal areas in water up to 100m deep. They were cemented to each other and often formed large colonies. It fed on microscopic food particles that were filtered out of the sea water.
The specimen was found in North Yorkshire.
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 |
