Description: | Specimen of a fossil bivalve (rudistid), Hippurites sp., collected from unspecified rocks of Late Cretaceous age. Collected by J. Hancock, 1889.
Rudists are an extinct group of bivalves (meaning two shells or valves) that lived in warm tropical seas. They had tube-shaped shells that were attached to the sea floor and grew like corals. The large tube shell contains lots of flat plates in the lower part and a small space in the upper part where the animal lived. The upper shell was held in place with soft flesh and fitted like a lid on the top of the tube.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Hancock, J.
