Description: | Specimen of a fossil crinoid (sea lily), Amphoracrinus gigas Wright, collected from the Carboniferous Limestone (?) of Early Carboniferous, Dinantian, Visean (?) age. Calyx.
This bud-shaped fossil is a crinoid calyx (cup) that is made up of many separate plates or ossicles. In life it was attached to the sea floor by a stalk and had tentacle-like arms to collect food. The position where the arms were attached can be seen around the middle of the calyx. 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 |
