Elaecrinus verneuili Blastoid Fossil

Here is a picture taken in 2009 at Coopers Lane Quarry in Clark County Indiana USA. It appears to be an Elaecrinus verneuili (Römer [aka Roemer], 1851) blastoid fossil embedded in limestone floor of the quarry. Stem segments of crinoids and blastoids are fossilized around it along with a Fenestella bryozoan netting fossil. All of this would be broken up by the quarry later but got an image of it before that happened. This layer might be the Jeffersonville Limestone and dates back to the Devonian Period.
