Lake Bridgeport Pennsylvanian Help

[gturner333]

I found these while going though some matrix from the FM2952/FM1658 intersection at Lake Bridgeport. The one I refer to as spines look a little like a thorn, but have a more fossil-like consistency when I crush them. The other two may or may not be related, but look so much alike that I put them in the same picture. Any ideas? And thanks in advance for the help.

The ones with the whorls look like the gastropod "Meekospira sp."

The some of the others look like possible partial cladodont shark teeth ? or genial spines of Ditomopyge.

Crush them?? Ok Gary I'm calling the paleo police

It's a clear case of "fossil abuse".

agreeed

i think the first photo contains trilobite genal spines.

Oh please don't call the "heat," Bob, I have over a dozen and sacrificed just one to see if it was plant or fossil. There have been several objects that look like a fossil but turned out to be a seed or something else more modern.

I checked out the genal spines and it looks like a good match. I have also found a few trilobite pygidium in this stuff, but they were small.

One of the others does look like a Meekospira stuck in matrix. There have been quite a few found here. I'm not sure about the other. Think it may be a crinoid spine?

I'll be starting my HR fossil diversity class tomorrow:(
