I have been to Graf, Iowa three times in the last 10 years and am always amazed at this site with the shear number of cephalopods exposed in the rock face. This fourth trip was made to find some material for a forum member. In doing so, I took the time to look closely at the matrix present at Graf. There were gastropods, brachiopods, bivalves ,graptolites, and even trilobites hidden in the rock. I had never noticed this on my previous trips since the cephalopods are overwhelming. I would love to go back another time soon and NOT look at the cephalopods at all, to see what I could find. I am here today to get Identification of the trilo-bits that I found at Graf. My guess is Thelecalymene mammillata. @piranha @DevonianDigger, if you still are looking for trilobits, I can send a few of these. 2018-10-009.cxf
Hello everyone, I found this large trilobite pygidium today which is the largest piece of trilobite I have ever found in the area, the pygidium measuring nearly 2 inches long. Judging by the trilobits I usually find I think the area is Devonian as I have trilobits I've previously found I believe are from eldregops and greenops. The problem with this site is it's imported material from somewhere in upstate new york so I'm not 100% percent sure. Though I believe it's devonian I don't know of any species with a pygidium this size personally so would anymore with more expertise help me find an ID of what species this can belong to, I'd love to know since I can't see myself coming across another one of these in the tiny area I get to look in.
Trying to help a college out with identifications on some of their specimens... I know this trilobite is a Trinucleid, but might anyone here more knowledgeable be able to deduce what kind it is further? Or POSSIBLE locations the piece may have come from (the labelling system once used has been lost with time)? Thanks for any help!
