Brachiopod shell and bryozoan
Shell with a hitch-hiker
This brachiopod, called Rhynchonella boueti, exists in huge numbers in the rock layer in which it’s found, the Boueti Bed. This specimen has a bryozoan growing on it – a tiny animal that grows on the surfaces of rocks, plants or animal shells. Bryozoans are filter feeder that sieve particles of food out of the water.
