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.

Carboniferous Bryozoan Fenestella

This picture is of a Carboniferous Period bryozoan called Fenestella membranacea. It appears to have been found in Algeria and is stored in museum in France.

More Mississippian Bryozoans

I am trying to figure out what these rings are on the rock I showed yesterday. This rock has layers of Fenestella all over it.

Is it a base for the bryozoan or maybe part of a blastoid?
All I have found at the Hodgenville, Kentucky site are bryozoan remains and some fragments of brachiopods and gastropods.

Fenestella Bryozoan

Here is bryozoan from the Mississippian period from Hodgenville, Kentucky I just found.

I am not sure the species but it appears to be genus Fenestella.


Here is something that is kind of neat. You can see lines squiggling around. Those lines are layers of Fenestella layered in the rock. They look like little lines of dots.
