Description: | This oyster shell has wide, angled ribs that have led to it being called the 'denture clam'. The zig-zag join between the two shells stopped coarse dirt and debris entering the shell and damaging its soft body. Like modern oysters it lived in shallow coastal waters including the intertidal zone (the area between high and low tide) and fed on food particles that it filtered out of the sea water. When this oyster died and its two shells separated before one was preserved in the beach deposit where it was found. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
