Bonehunter Posted March 18, 2021 Share Posted March 18, 2021 I'm hazarding a guess as a P1 element of Idiognathodus?, or is it something else? seems a little wide for a conodont? Pennsylvania stark shale. Yeah or neigh? Thanks! Bone Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 18, 2021 Share Posted March 18, 2021 Seems a reasonable ID. @jdp Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

jpc Posted March 18, 2021 Share Posted March 18, 2021 what is a P1? As a guy who collects fossil mammals, a P1 is an upper first premolar. I don't think that is what you have in mind. Link to comment Share on other sites More sharing options...
minnbuckeye Posted March 18, 2021 Share Posted March 18, 2021 @jpc, I hear P1 and think first phalange. Did that snow storm hit you? I heard huge of amounts in Cheyenne. Link to comment Share on other sites More sharing options...

I don't think that is what you have in mind. My understanding is conodont "teeth" are classified, in part based on general shape and position in the "mouth" as S, P and M, S segments are subclassified into Sa, Sb and Sc. Then P is subclassified as Pa and Pb. I don't believe, but I am not sure there is any connection to the dental formulas that are standardized in mammalian species.

Believe me, I was also initially (and still ) confused, but I understand a little better now-you have to look at this separately from any other animal description. The "teeth" segments are specifically arranged in the mouth and each is labeled accordingly-quite extraordinary in some species!.......many more to follow! Thanks for looking!!!

jpc Posted March 19, 2021 Share Posted March 19, 2021 Thanks for this info. Yes, we got 23 inches of snow (65 cm). School was closed for two days (it would have been three days if the kids had school on Sunday). Link to comment Share on other sites More sharing options...
doushantuo Posted May 9, 2023 Share Posted May 9, 2023 (edited) you might be on the right track there,btw the P1 is variable,which makes exact determinations imperative,it being a marker species for the Midcontinent Pennsylvanian Orientationandanatomicalnotationinconodonts.pdf Edited May 9, 2023 by doushantuo Link to comment Share on other sites More sharing options...
