PetrolPete Posted March 26, 2013 Share Posted March 26, 2013 (edited) When I went up to Kansas City last week, I got some Eudora Shale (Upper-Pennsylvanian, Stanton fm.) from Bullsnake (thanks again for the shale) to look for Conodonts in. Here are a few of the better ones kindly ID'd by Missourian. All pictures are taken at 60x.

PetrolPete Posted March 27, 2013 Share Posted March 27, 2013 A few more conodonts from the Eudora Shale (Upper-Pennsylvanian, Stanton fm.) Kansas City area. I'm not sure on the names of these either.... Link to comment Share on other sites More sharing options...
Missourian Posted March 27, 2013 Share Posted March 27, 2013 (edited) I think pics 2, 4 and 6 are Ozarkodina. Pics 1 and 5 may be (partial?) Ozarkodina as well, but they also resemble some type I can't recall at the moment. Pic 3 is likely Gondolella. Pic 7 could be a partial Ligonodina. Pic 8 could be Idioprioniodus or the central point of Hibbardella. Edited March 27, 2013 by Missourian Context is critical. Link to comment Share on other sites More sharing options...

From what I can tell, 1 and 5 don't appear to be partials (I could be wrong), but it's a definite possibility that 7 and 8 are partials Link to comment Share on other sites More sharing options...

I have some pictures of Devonian conodonts and vertebtrate microfossils from the North Evans LS in Western NY posted on my website: http://bingweb.binghamton.edu/~kwilson/Devonian/DevMicros/Micros.htm Hi Dr Wilson, do you have the conodonts and microvertebrates from the same rock sample? There are a few interesting teeth there and I think you have a few ctenacanthid scales as well. And to add. Palmatolepis bogartnesis. I think, cant remember the species id.

MarcoSr Posted June 23, 2014 Share Posted June 23, 2014 Nice specimen and pictures. It is difficult to take pictures of them also without damaging them as they can be very fragile.

Ludwigia Posted November 18, 2014 Share Posted November 18, 2014 (edited) I thought I'd dig up this old thread in order to show a few conodonts that I've just discovered in a few blocks of North Evans Limestone (Moscow Formation, Middle Devon) which I brought back with me from my last trip to Penn Dixie in October this year. I tried fiddling around with acetic acid on a little piece in order to get some out, but the solution was too strong and I ended up dissolving the fossils along with the limestone overnight So, since I tend to be somewhat impatient, I decided just to give the blocks a onceover with the air abrader at low pressure to see what appears. That worked out ok. They're of course not available for the eye in complete 3D, but it's good enough for my purposes. I had to familiarize myself with the taxonomy for purposes of identification, but I just more or less got lost in the jungle of the original "multielement" taxonomy and the more updated attempts to turn that into a normal systematic, now that the culprit has at last more or less been identified (it's something like an archaic miniature lamprey eel). I stuck to the multielement taxonomy in the end, but there are so many slight variations in form that I'm not at all sure if my ids are correct. Karl Wilson was able to give me a bit of advice and sent me some literature (thanks Karl), but maybe someone out there could also correct any mistakes I may be making. All of these ids have a question mark attached. I took the photos at the ocular of my microscope with my digital camera at magnifications of from 30-50x. Some are a bit blurry, but most have turned out ok for an amateur. Polygnathus caelatus Polygnathus rotundilobus (right) and Prionodus sp.

Mediospirifer Posted November 19, 2014 Share Posted November 19, 2014 Thanks, although it's really hard to get them in focus sometimes. I have the same problem! I try to get around it by taking lots of pictures, then throwing most of them away.... You do have some nice examples. Do you have a good reference for identifying North Evans conodonts? This is the best resource I've found so far: LINK Enjoy! Link to comment Share on other sites More sharing options...
