Three Types of Crinoids + Coral - Crawfordsville, Indiana

 
This is a wonderful association of FOUR different types of crinoids from Ramp Creek Limestone. The largest crinoid on the piece is a 2.8" long Scytalocrinus decadactylus. The second largest on the edge of the plate is an Undescribed inadunate crinoid. The 3rd largest is a Hylodecrinus gibsoni.

It is believed that crinoids from the Ramp Creek Limestone were buried in sediment from nearby deltas during storms. The resulting siltstone deposits are soft enough that fossils can be extracted in exquisite, three-dimensional relief.
