Description: | Specimen of a fossil trilobite, Ogygiocarella angustissima, collected from the Llandeilo Flags of Middle Ordovician, Llanvirn, Llandeilian age from Builth Wells, Powys (Wales). Collected by Joseph Duff.
Trilobites are so named because their shells are divided into three lobes. Their shells are made up of a central ridge (called an axial lobe) with a lobe on each side (called pleural lobes). The broad flattened shape of the shell suggests that this trilobite crawled on the seabed scavenging for food.
The specimen was found in Wales.
It is from the Ordovician period (495 - 443 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Joseph Classification: Animalia Duff Invertebrata Trilobita Arthropoda | Temporal: | Ordovician period (495 - 443 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
