Bringing Fossils to Life Posted January 8, 2022 Share Posted January 8, 2022 Here is the complete guide to the Mahantango ammonoids! Koenenites is only included because of two specimens (found by my friend and I) from Swatara Gap, which includes some Mahantango strata according to HynerpetonHunter. Tornoceras is the most common, Koenenites the rarest. Enjoy! 8 Link to post Share on other sites
Fossildude19 Posted January 9, 2022 Share Posted January 9, 2022 I'd be interested to see good photos of the specimens you have collected of these. Link to post Share on other sites

ScottBlooded Posted January 9, 2022 Share Posted January 9, 2022 Very cool, I’ve found a number of agoniatites out in the needmore formation in WV. 1 3 Link to post Share on other sites
Bringing Fossils to Life Posted January 10, 2022 Author Share Posted January 10, 2022 Nice specimens! I just took pictures of my Koenenites, and here they are. If you are skeptical, check the suture lines and you will see the main saddle comes sooner instead of later; also there is no other Devonian ammonoid around with such a sharp keel (it is sharp to the touch). Unfortunately, The specimen has pyrites disease, and when I had recently identified it as an ammonoid (thanks to HynerpetonHunter), I unsuspectingly brushed part of the umbilicus away. It has only gotten worse, and I found not to use Elmer's glue on specimens that might be of value. Is there another inexpensive way of getting rid of it? I have used the same brush on all my fossils, and don't want pyrites disease spreading everywhere. Do you have any suggestions? The second and third to last are not only for scale but also to compare with an Agoniatites from Seven Stars quarry. I have also included my reconstruction of Koenenites. 2 Link to post Share on other sites
Bringing Fossils to Life Posted January 10, 2022 Author Share Posted January 10, 2022 The fourth picture is the impression of where the "end of the shell" is missing, showing the suture from higher up in the venter ("end of the shell" because if you look on the left of most of the picture you will see the impression and part of the original shell from the next whorl, showing that the whole shell was likely around 2.5 cm across in life).

FossilBaron Posted January 21, 2022 Share Posted January 21, 2022 Very interesting! I didn't know there were goniatites from Seudberg. I'll have to keep an eye out for them next time I'm out there. Link to post Share on other sites
Uncle Siphuncle Posted January 21, 2022 Share Posted January 21, 2022 Great stuff. I don’t get my hands in the Devonian often, but I found similar in a Needmore road cut a dozen years ago or more. Link to post Share on other sites

pefty Posted November 17, 2022 Share Posted November 17, 2022 Amazing! Would you up for sharing your template (Creative Commons perhaps) so that the rest of us can create our own matching cephalopod faunal graphics while giving you credit for the design elements? Link to post Share on other sites
Bringing Fossils to Life Posted November 18, 2022 Author Share Posted November 18, 2022 By template, what do you mean? I can post important resources I used, but I ultimately draw these on paper before digitizing them. I also use Paint.net, a raster program, and the different layers I use can only be differentiated when they are in Pant.net format, which only Paint.net can open. What do you want to access?

pefty Posted November 28, 2022 Share Posted November 28, 2022 (edited) Ah, it looked so clean I thought it was in some vector format. Really I just wish there were a guide like this for every fossil fauna, or at least every cephalopod fauna. And since there isn't, I'm in search of streamlined ways of creating them. thanks for the info on your process. Edited November 28, 2022 by pefty more thoughts :) Link to post Share on other sites
