Missourian Posted January 15, 2013 Share Posted January 15, 2013 (edited) I'm pretty sure this is a crustacean of some sort: It measures 7 mm from 'arched back' to 'tips'. It was found in a phosphatic nodule from a black shale. Associated fossils include the crustacean Concavicaris, ammonoids, fish, and conodonts. It came from the Muncie Creek Shale in the Kansas City metro. I'm hoping someone here could narrow down the id. Edited January 15, 2013 by Missourian Context is critical.

RCFossils Posted January 15, 2013 Share Posted January 15, 2013 Neat piece! Definately looks shrimpy. I hope someone knows what it is Link to comment Share on other sites More sharing options...
Auspex Posted January 15, 2013 Share Posted January 15, 2013 Niiice! Looks like a peeler shrimp (in part because I haven's had lunch yet).

AgrilusHunter Posted January 15, 2013 Share Posted January 15, 2013 Beautiful! I would agree it looks like you have the carapace and abdomen of a shrimp. This looks like it would prep out even more as well. The preservation is outstanding!

Roz Posted January 15, 2013 Share Posted January 15, 2013 Wow, I had heard crustaceans could be found in the Pennsylvanian but have never found even a scrap.. Congratulations, a great addition to your collection! Welcome to the forum! Link to comment Share on other sites More sharing options...
Missourian Posted January 15, 2013 Author Share Posted January 15, 2013 Thanks everyone. The encouraging comments leave me confident that at least its id as a crustacean is on the right track. .....This looks like it would prep out even more as well. ..... I'm happy with it as is. With my luck, I'd be poking at the matrix, and a piece of the carapace would just vanish from sight and end up in the carpet somewhere on the other side of the room. Wow, I had heard crustaceans could be found in the Pennsylvanian but have never found even a scrap.. Although this is the only complete one I've seen personally (not including those 'identified' with 'confirmation bias' ), various pieces of crustaceans aren't too terribly uncommon in Muncie Creek nodules. I would be surprised if some don't eventually turn up in your Texas concretions. Context is critical. Link to comment Share on other sites More sharing options...
piranha Posted January 16, 2013 Share Posted January 16, 2013 ...I'm happy with it as is. With my luck, I'd be poking at the matrix, and a piece of the carapace would just vanish from sight and end up in the carpet somewhere on the other side of the room... That reminds me of one of my near blunders. Years ago I was poking and prepping on a prized trilobite until it was almost too late. Luckily I saw the 2mm genal spine tip when it went flying across the room.... even luckier it wasn't carpet. Still, it took me about an hour to find it and fix it, never to touch it again! Agreed, good is good enough. Link to comment Share on other sites More sharing options...
