Description: | Specimen of a fossil bivalve, Trigonia sp., collected from unspecified rocks of Cretaceous age from France.
The name of this bivalve describes its triangular shape. Its shell is covered with angular ridges and hollows that made it strong. Trigonia burrowed in the surface of coarse shelly sand in areas near the coast, including the intertidal zone (the area between high and low tide). It was a filter feeder that extracted food particles out of the sea water. Trigonia lived all over the world in the Cretaceous period. Living relatives are found today but only around the coast of Australia.
The specimen was found in France.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia, Invertebrata, Mollusca, Bivalvia | Temporal: | Cretaceous period (144 - 65 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
