This is a Cockerellites I found last year and had prepped out. It came out in a pretty gnarly split and had to be glued back together and prepped. With slight restoration it turned out very well. Looking closely at the anal fin spines, you'll notice the pathology, this specimen has 4 instead of the usual 3. This is most likely a pathology of a Cockerellites liops instead of a new species.

I thought I'd try my hand with this Kemmerer Cockerellites liops this time around. This took me a looooong time because of the fine differences in shading, but I'm pretty happy with it. As you can see when compare to the original photo, I cheated a bit on it by filling in the missing parts of the fins.

Cockerellites I prepped roughly a month ago
KompsFossilsNMinerals posted a topic in Fossil Preparation
This is a Cockerellites I prepped about a month ago. I used a dremel lightly to get the top layer of matrix off, then used a regular pick for the finer preparation. For my second Cockerellites prep ever, I think I did a pretty good job. The coolest part of this piece is that there is a long piece of coprolite(?) ontop of its head. I have no clue if this would bring up the value, I kind of doubt it would though.

Finished this fish yesterday, preservation wasn’t terrible. The head Isn’t preserved well and neither is the tips of the fins but anything is better than my first prep which was on an exploded knightia. Could of turned out better but I’m satisfied with it. I have a couple questions. 1. can you tell if it is a priscacara or a cockerellites? I believe they are two different genera with different species. 2. What is the part in front of the fish’s head? It’s not bone, it’s very thin and different, I have no idea what it is. Oh and I was prepping with a not so sharp needle thing, criticism and tips are welcome

This fish came out of the upper layer, "money layer", at American fossil. They no longer allow pulling rock off the wall here. Changed genus from Priscacara: http://www.thefossilforum.com/index.php?/topic/100366-december-2019-finds-of-the-month-entries/&do=findComment&comment=1120047 Lit. John A. Whitlock, 2010.
