Crinoid Fossil Platycrinites Hemisphericus Carbiniferous Indiana 

Platycrinites Hemisphericus from an old collection. Crinoids are also commonly known as sea lillies. Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). Crinoidea comes from the Greek word krinon, "a lily", and eidos, "form". They live both in shallow water and in depths as great as 9,000 meters (30,000 ft).Sea lilies refer to the crinoids which, in their adult form, are attached to the sea bottom by a stalk. Feather stars or comatulids refer to the unstalked forms. The fossil comes with an acrylic click and twist display stand.
