Description: | This brachiopod (lamp shell) fossil has a strong shell with a distinctive fold along its midline. The plicate (zig-zag) join between the two shells stopped coarse debris clogging up the brachiopods feeding mechanism. These features show that Cyclothyris lived in high-energy shallow water seafloor communities. The shell was attached to the sea floor by a pedicle (fleshy stalk) that grew through the round hole in the larger shell. The brachiopod fed on microscopic food particles that it filtered out of sea water. | 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 |
