ARE CRINOIDS A SEA LILY?
Because of their “flower like” appearance, crinoids have also been referred to as “sea lilies”, however they are in fact animals. Indeed Crinoids belong to the phylum Echinodermata.

WHAT MAKES CRAWFORDSVILLE CRINOIDS SO SPECIAL?
Crawfordsville Indiana is known for its spectacular crinoid faunal assemblage. There are more than 60 species of crinoids among more than 40 genera found in the Crawfordsville area. Seafloor conditions in the Crawfordsville area were obviously very favorable to the proliferation of crinoids, an environment that had both shallow water conditions and an influx of silt from a neighboring delta.
Mississippian Age crinoids from Crawfordsville, Indiana, are known worldwide for their completeness, abundance, comparatively large size, and extraordinary aesthetic appeal.
