Paciphacops Posted February 24, 2018 Share Posted February 24, 2018 Found this little guy yesterday in the Ordovician Carter's limestone, middle TN. Just a glabela and one eye, but clearly something different than the typical fossils from the Carter's. I'm thinking it may be Raymondites sp.?

Tidgy's Dad Posted February 24, 2018 Share Posted February 24, 2018 Nice find. The glabella looks right, but not sure about the eye. Others will have more experience with this I hope. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
caldigger Posted February 24, 2018 Share Posted February 24, 2018 Get some of that rock off and let's see what we have. Link to comment Share on other sites More sharing options...
DevonianDigger Posted February 24, 2018 Share Posted February 24, 2018 Seems plausible that it’s a Raymondites sp., glabella looks right and in the right proportion to the eyes. Would need to clear out that post-occipital area to really be able to tell if the eyes are right. I agree with @caldigger, needs some matrix removal to be sure! Jay A.

piranha Posted February 24, 2018 Share Posted February 24, 2018 Yes, the eyes are correct. Check out this paper: Swisher, R.E., Westrop, S.R., & Amati, L. (2015) The Upper Ordovician trilobite Raymondites Sinclair, 1944 in North America. Journal of Paleontology, 89(1):110-134 PDF LINK Link to comment Share on other sites More sharing options...
piranha Posted February 24, 2018 Share Posted February 24, 2018 Additional prep may reveal a possible occipital spine. Raymondites cf. ingalli is shown for comparison: Link to comment Share on other sites More sharing options...
Paciphacops Posted February 24, 2018 Author Share Posted February 24, 2018 The thin piece of matrix is very hard, yet very fractured. I tried to remove a little matrix at the rear, and it started to fall apart, so I am soaking it in dilute paraloid B72 to stabilize it. However, there does not appear to be much else present on the rear of the glabela as far as I can tell. There is a little more on the front end under the matrix, so I may try to remove a little more later. At least I know these are present, so maybe I can find a better one next time. Thanks!
