Waldron shale Eucalyptocrinus Crassus Fossil Crinoid Indiana Usa

Description

Here I'm offering up a nice Eucalyptocrinus from the Waldron Shale formation of Shelby county, Indiana.  This crinoid boasts the interbrachial arm supports and the arms or colloquially termed "inner arms" on one side. This crinoid is of good size measuring in at 2 inches (~6 cm) long.
