Placoparia tournemini, Ordovician trilobite fossil. Trilobites were arthropods that fed as they crawled on the seabed. They lived between 500 and 300 million years ago and are now extinct. This specimen dates from the Middle Ordovician, and was found in the Llandeilo Series, Mortain, Brittany, France. The cephalon has deep furrows. There is an absence of eyes (this specimen is blind). The thoracic pleurae turn sharply downwards at the terminations, and the pygidium ends with a 'frill'. This specimen is centimetres long.
