snakebite6769 Posted April 3, 2013 Share Posted April 3, 2013 (edited) ok I am asking for help identifying these two fossils..the first is from Davenport Iowa, I found it along the Mississippi River. I did some minor prep work with a scribe and was surprised at what I saw. Little spikes..? all around it, I also have another similar one with some color to it with two large spikes protruding forward from the rear hinge point. The second was found at Dresden Generating Station (Morris Illinois) in the crumbled rock they use for fill. (I got bored and had to check out the rocks) It appears to me to be a type of Illaenus sp. but which one I dont know.

squalicorax Posted April 5, 2013 Share Posted April 5, 2013 The first looks like a productid brachiopod. Would need to see more angles My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...

FossilDAWG Posted April 6, 2013 Share Posted April 6, 2013 I agree with the productid brachiopod ID for the first one. Preservation is not great, but the spines and the overall shape are characteristic. Don Link to comment Share on other sites More sharing options...
