An echinoderm of the class "Crinoidea", which comprises the sea lilies and feather stars.
- ‘Commonly, the host is a brachiopod, but it may be a coral, bryozoan colony, crinoid stem, or mollusk.’
- ‘Echinoid and crinoid fragments are preserved on a number of bedding planes, indicating normal salinity levels.’
- ‘The entire fauna is typically shallow-marine, composed of crinoids, brachiopods, corals, and bryozoans.’
- ‘A very productive synergism developed among crinoid biologists, crinoid paleontologists, and those who worked in both fields.’
- ‘Gogia is an eocrinoid, a member of a grouping of early echinoderms that probably included the ancestors of true crinoids and other echinoderm taxa.’
Relating to or denoting crinoids.
- ‘The Graphic mine in the same district is known for smithsonite replacements after crinoid stems and mollusk shells.’
- ‘Most of the sphinctozoans and crinoid stems are found almost complete and articulated, lying parallel to bedding.’
- ‘Alpha taxonomy must still play a vital role in the crinoid research agenda.’
- ‘The fauna is dominated by common fenestrate bryozoans and crinoid ossicles.’
- ‘Grainy rocks in the upper third contain an abundance of disarticulated crinoid debris.’
