What Are Crawfordsville Crinoid Fossils?
Crinoids are marine animals belonging to the phylum Echinodermata. Therefore, they are relatives of modern starfish, sea urchins, and brittle stars. Although crinoids resemble flowering plants, they are actually animals.
These prehistoric creatures typically had long, flexible stems attached to the seafloor. Above the stem, a cup-shaped body called the calyx supported numerous feather-like arms. These arms captured tiny food particles from surrounding seawater.
Because of their flower-like appearance, crinoids are commonly called sea lilies. Interestingly, living crinoids still inhabit modern oceans.
Why Are Crawfordsville Crinoid Fossils So Special?
Crawfordsville, Indiana, is one of the world’s most famous fossil crinoid localities. During the Mississippian Period, warm marine waters covered much of this region. Consequently, large communities of crinoids flourished across the ancient seafloor.
Occasionally, sediment rapidly buried these animals. As a result, many fossils retained delicate structures that normally separate after death.
Unlike ordinary crinoid stem fragments, exceptional Crawfordsville specimens may preserve complete crowns, arms, stems, and tiny feeding structures. Moreover, some fossils contain several crinoid species together on one natural limestone or siltstone matrix.
