Hello everyone, sorry to be posting so much Florissant fossil quarry material, but I'm going through my collection of foliage and still need these ID'd. Most of these leaves are obviously pretty common, but I can't find some of them in the book Fossils of Florissant. So here they are: 1. Think it's a Fagopsis, but just double checking. 2. Don't really know, feeding traces around the edges.

I have a coprolite that has me somewhat puzzled. It was found in a river in South Carolina and dates Miocene-Pliocene. I picked it up at the Tucson Gem Show because I thought it resembled some east coast coprolites with longitudinal striations/furrows/grooves that @MarcoSr posted a while back. Now that I've looked at it for a while and done a little prep work, I'm not so sure the grooves are sphincter related. There are intestinal muscle marks visible on one side, but they don't seem to match up with the grooves. The grooves were filled with sandstone/limestone. I left matrix in the deeper portions to preserve the integrity of the specimen. Across from the grooves are what look like puncture marks. My first thought was that they were clam borings. However, they do line up with the grooves in question. Now I'm wondering if these could be tooth marks as well. Under magnification, I noticed smaller tooth marks and an impression that I can't figure out. My imagination is now getting the best of me, and I'm seeing food chain activity. I'm seeing a big fish nabbing a small fish that was nabbing an invertebrate that was feasting on feces. Do you think the larger grooves and holes could be tooth marks? Does anyone have any idea what could have left the impression? The only thing I could think of is some sort of mollusk. Love your thoughts on this. @Carl
