Large Lichida Trilobite Fossil


A well preserved Lichida Trilobite Fossil from the Furongian to the Devonian period. The fossil is embedded in stone and displays several distinctive features. The thorax (body), consists of many segments with spine-tips and a central axis. Two raised small, globular, holochroal eyes sit on the lower part of the large triangular shaped cephalon (head). At the base of the trilobite is a tail-shield known as the pygidium.

Date: 500 million years old
Period: Furongian - Devonian period
Condition: Good condition - there are some earthly encrustations on the fossils surface.

Trilobite – meaning “three lobes” – refers to an extinct class of marine arthropods. The arthropod family included invertebrate animals with an exoskeletons and a segmented body. Lichida in particular are known for their elaborate and pronounced spines used as a defence mechanism to warn off predators. They usually have between eight to thirteen segments. Trilobites became extinct around 250 million years ago, in the late Permian period. This was during the Permian-Triassic extinction event – which is thought to have been caused by ocean acidification. Many other species – like Gonitatie Ammonites – disappeared in this event, often referred to as the ‘Great Dying’.
