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.
