Mainefossils Posted March 5, 2021 Share Posted March 5, 2021 Fossil forum, This is another fossil from the Leighton Fm. I just finished recovering it from some fossiliferous rock I brought back with me. It is about 575 microns long. Any help on its id would be appreciated. Here is a picture of it: The more I learn, the more I find that I know nothing. Regards, Asher Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 5, 2021 Share Posted March 5, 2021 Scolecodont or conodont, perhaps? 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Mainefossils Posted March 5, 2021 Author Share Posted March 5, 2021 Great, thanks! I was also considering agnathan scales - do you think that's a possibility as well? Thank you!

Fossildude19 Posted March 5, 2021 Share Posted March 5, 2021 I don't know, not familiar with agnathan scales. @jdp Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

jdp Posted March 5, 2021 Share Posted March 5, 2021 Thelodont seems possible, although my initial reaction was chondrichthyan. The structure also seems kind of like what individual teeth look like in stem-osteichthyans like Lophosteus and Andreolepis, but you also see small denticle plates like this in some "primitive" placoderms. Realistically any of these could be present in Pridoli-aged microfossils. In any of these cases, the fauna might actually be important, so it might be useful to send a picture of this on to a professional who specializes in these faunas. 4 Link to comment Share on other sites More sharing options...
Mainefossils Posted March 5, 2021 Author Share Posted March 5, 2021 Thanks so much for the information! Do you have a person you would suggest? The more I learn, the more I find that I know nothing. Regards, Asher Link to comment Share on other sites More sharing options...
