Description: | Specimen of a fossil crinoid (sea lily), Pachylocrinus dunlopi Wright, collected from the Carboniferous Limestone of Early Carboniferous, Dinantian, Visean (?) age.
This specimen shows the three main parts of a crinoid; a stem that was attached to the sea floor, the calyx (cup) that contained the fleshy body and the tentacle-like arms that were used to collect food. It also shows that all the parts are made up of many separate plates or ossicles. Crinoids lived in warm tropical seas in varying water depths. They often formed large colonies known as gardens and were an important component of reef communities. Crinoids (sea lilies) are actually animals related to star fish.
It is from the Carboniferous period (362 - 290 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Crinoidea Classification: Animalia Echinodermata Invertebrata | Temporal: | Carboniferous period (362 - 290 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
