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. The opposite side is largely washed out. One neat feature about this specimen is the pyrite clusters that are dotted along the arms. This crinoid measures in at one inch (3 cm) long.
