Found in Kentucky along AA Highway, Ordovician, Kope formation. I took it because it looked like a weird eyeball thing. I didn't think it was a fossil, just a weird rock, until I cleaned it off and found a bunch of trilobite bits on it. So that had me wondering if it was a trace fossil or if there might be something inside if I chipped away at the shape. Honestly I'm kinda itching to see if there is anything inside it. As it sorta, to my untrained eye, looks like something fell into the water about an eon ago and got covered up. However I don't want to take the Dremel to it if it is more or less just a trace without chance of anything being locked away in there. So I'm just trying to get the thoughts on it from other people way more knowledgeable than me about the matter. Thanks in advance.

I found this mortality plate along AA Highway in Kentucky. Area is ordovician. I've been cleaning on this plate all night, when found this little guy under some dirt and brachiopod fragments. Did I just find a flexicalymene trilobite head? I know it's just a fragment and not the full thing. But I'd be pretty stoked if I'm correct on this. Thanks in advance. (I traced it out just in case my picture is too poor to see it. I can't find my macro lens)

I picked this up on my last trip along AA highway in Kentucky. It's about 4cm long. I thought it was a crinoid stem. Recently I saw a YouTube video where someone found a fossil very similar to this and called it a cephalopod. So that left me confused. So I figured I should just post and ask here. (If I need to provide more information or pictures please let me know)

A few weeks ago I went along AA Highway here in Kentucky and collected a number of mortality plates from the side of the road. I had cleaned up this plate and had it sitting to the side as I tried to figure out how I was going to display it. One of my cats knocked it over last night and split off a chunk that exposed this concretion looking thing that was hidden beneath the top layer of crushed brachiopod shells. Unfortunately when I picked it up to examine it, the top of this concretion looking thing fell off. It sent little fragments everywhere. When I looked back to the main part of the mortality plate I saw this shape. I'm not sure if this is anything of any importance or just an anomaly of the rock. My brain keeps telling me that it looks like bone of some sort (well impression of bone), but I know I'm not experienced enough to know. I collected the top of the concretion looking thing and what fragments I could find and took a picture of them as well. I couldn't pick up the other fragments as they just crumbled in my fingers. Also, I guess it's would be important information this concretion looking things is a little over 3 inches long and about an inch and a half wide. Did my cat just find something of importance in my mortality plate?

First of all, is this a hypostome? If so, is it a damaged one from Isotelus? Found in the Kope Formation, Ordovician along AA Highway in Kentucky. Thanks for looking at it and giving an opinion. Mike

Today I drove from Northern Illinois into Indiana, over to Ohio and down into Kentucky to do some collecting on AA Highway. I stopped and spent 7 1/2 hours at 4 sites along AA, I will start with my first stop which was located in Wilder, Kentucky. I believe that this is the Kope Formation and is Upper Ordovician in age. Here are some of my finds- I only found one sort of complete trilobite- Flexicalymene sp. Here are a bunch of trilo- bits of Flexi and the lace collar trilobite Cryptolithus sp. This location had numerous loose Sowerbyella sp. brachiopods. I did find one bi valve- I find one plate that had some graptolites- I found a couple cephalopods- A couple cool Crinoid stem plates- This may or may not be something- Site 2 on next post.
