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 world-famous for its spectacular crinoid fossil assemblage. More than 60 crinoid species representing over 40 genera have been discovered in the Crawfordsville area, making it one of the richest crinoid localities ever found. These remarkable fossils indicate that the ancient seafloor provided ideal conditions for crinoids to thrive. The shallow marine environment, combined with a steady supply of fine silt from a nearby river delta, created a nutrient-rich habitat that supported an abundant and diverse crinoid community.
Mississippian Age crinoids from Crawfordsville, Indiana, are known worldwide for their completeness, abundance, comparatively large size, and extraordinary aesthetic appeal.
