Description: | Specimen of a fossil trilobite, Calymene sp., collected from unspecified rocks of Silurian (?) age.
These animals are called Trilobites because the jointed shells which protected their bodies are divided into three parts. These three parts are shown very well in this specimen. It has a well-developed head and a middle section called a thorax. This consists of a series of flexible plates. It also has a well-developed 'tail' called a pygidium that consists of a series of plates that are fused together. Trilobites like this one are thought to have crawled across the seabed scavenging for food.
It is from the Silurian period (443 - 418 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Invertebrata Trilobita Arthropoda | Temporal: | Silurian period (443 - 418 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
