Description
Fossil trilobite, Ogyginus corndensis corndensis (Murchison), from the Ordovician period (500 to 435 million years ago), found in the Lower Llanvirn sediments, Builth Wells inlier, Powys, Wales. Slight differences can be seen between this specimen and that shown in E442/136: it has been suggested that this could be an example of sexual dimorphism. The trilobites are an extinct group of marine arthropods, which were distributed throughout the prehistoric oceans. Most trilobites lived on the sea bottom, although some burrowed in sediment and a few were swimmers.
