Description: | Specimen of a fossil brachiopod (lamp shell), Pterospirifer alatus, collected from the Raisby Formation (?) of Late Permian, Zechstein (Durham Province), EZ1 age from East Thickley, Shildon, Co Durham (NE England). Collected by James Walter Kirkby.
Pterospirifer alatus was a brachiopod (lamp shell) that lived on a reef (a ridge made up of living animals and the remains of dead animals under the water). It lived in the Zechstein Sea in the Sunderland area 250 million years ago. This shellfish attached itself to the sea floor with a pedicle, a thin muscle that passed through a small hole in the top of the shell. These brachiopods are always found on their own, so they may have lived singly, rather than in groups.
The specimen was found in Co Durham.
It is from the Permian period (290 - 248 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Kirkby Brachiopoda Invertebrata Articulata James Walter | Temporal: | Permian period (290 - 248 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
