Description: | Specimen of a fossil bivalve, Psammobia solida J. Sowerby, collected from the Solent Group, Headon Hill Formation of Tertiary, Late Eocene, Priabonian age from Colwell Bay, Isle of Wight, Hampshire (SE England). Collected by William K. Loftus.
This large, freshwater bivalve has equally sized elongate convex (outward curving) shells. The smooth, thin shell with regularly spaced growth lines, shows that Psammobia lived in a low-energy (calm water) environment. The rocks that it was found in were deposited in fresh and brackish (slightly salty) lakes and lagoons on a low lying subtropical coast. The bivalve lived in a vertical position within a shallow burrow on the lake bed and fed on small food particles that it filtered out of the water.
The specimen was found in Hampshire.
It is from the Tertiary period (65 - 1.8 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Invertebrata Bivalvia Mollusca William K.
