Description: | Specimen of a fossil brachiopod (lamp shell), Orthis spiriferoides M'Coy, collected from the Bala Group of Late Ordovician, Caradoc - Ashgill (?) age from Llanbedrog, Gwynned (Wales). Collected by E.J. Garwood.
Orthis is a kind of brachiopod (lamp shell) and is a fairly common fossil found in Ordovician rocks. This specimen has a distinctive raised ridge in the centre of the shell. Brachiopods like this one lived attached to the seabed and fed on tiny particles filtered from the water by a special feeding organ, called a lophophore, within the shell.
The specimen was found in Gwynedd.
It is from the Ordovician period (495 - 443 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia E.J.
