Fossils (Inventory)/Crinoid

From LagWiki

An exceptional example of a crinoid. Most are much more difficult to recognize.

The Crinoid field should be used to record stations where crinoid fossils are found.

Crinoids are a marine animal which may be preserved in the bedrock as fossils. These fossils may then be exposed.

A complete crinoid looks like a lily with what appear to be roots, a stem and a flower; but, they are not plants but animals. Any portion may be exposed as a fossil; but, usually, the fossils are a cross section of the long stem and it appears like a stack of buttons.

Crinoids may be difficult to recognize and obscured by other formations. Look for them anywhere bedrock is exposed including breakdown.
