are any of these pix from clearfield or centre county in penna ?
ReplyDeleteNo, most are from Central Pennsylvania in the Perry County and Juniata County area.
DeleteOk so I got around to measuring the shell from Fulton County. It is 1.5 inches long and about 2 inches wide. It has a wrinkled edges on both sides. There are distorted ribs going down it and some spines near the hinge and the anterior margin. There are only proetid trilobites found near it. Is it still Linoproductus?
ReplyDeleteThe trilobites are small, about a half inch long. They have 12 thoracic segments and ribbed pygidium with a border, and therefore aren't Phacops. I was thinking they weren't Devonian as the only trilobites I find are like that. The cephalon is small with genal spines and a "segment" at it's base also it doesn't have turbecles.

DeleteSorry... www.thefossilforum.com. Try posting some pictures of your finds there and you will get some good responses from the locals.
ReplyDeleteThanks for the reply. I had it looked at along with the trilobites. The guy said it was Pentamerus from the Silurian. The trilobites were Calymene. The apparent spines were really pieces of rock. Thanks for the help. I appreciate your trying to help.
ReplyDeleteI wasn't to confident in the Calymene id for the trilobites so I had another couple of guys more familiar with Pennsylvanian and Permian material take a look. My suspitions were correct as they both agreedthat the trilobites were Ditomopyge decurata. They were confused at first with the brachiopod but agreed that it was indeed Linoproductus pattenianus. They even identified another brachiopod as a possible Leptodus.
