Hi all literally just got back from trip ad just split this bit of shale which has lots of detrital bits in it but this was looking at me !! looks like Orthacanthus s.p tooth but as I say Im no expert

if it is not, any ideas as to what it may be ?

Hey Chris,
Certainly looks like this one I found in a google search.

Congratulations on a great find!
Regards,

Any idea of what fauna have been previously found here? Is there any published material on the formation you are hunting? Some Xenacanthus teeth look similar as well, and it was a smaller shark... maybe a possibility?

Hi Tim hmm yes Xenacanthus is a possibility , I havent found any information on the spot Im hunting as yet , (seems to be a fresh site ) , but I do know fish remains have been found in other places of the U.K with westphalian-A deposits of marine shale in the coal measures

Hope it is helpful.

Cool tooth. I have one like it that I've been calling Xenacanthus.

Well, hey, I happen to have an image available:

The only certainty with fossil hunting is the uncertainty.

Hi Darren thanks ,

The circle is part of the tooth which I found when I thought it wasnt and went to brush it off , I soon realized it was part of the whole

also yes I did use my usb scope but only on level 10x magnification I could probably take a normal photo its big enough for that

Hi all update on Id for this tooth reply from Jenny the expert I sent photos too

Hello! My PhD student who's studying chondrichthyans of this age says that
yes, it's a xenacanthomorph, and probably belongs to the subgroup
Bransonelliformes. It may belong to the genus Barbclabornia, although that
genus is generally found a bit later, from Late Carboniferous to Early
Permian. Interesting.

Best wishes, Jenny

Hi Tim yes it is very exciting , I wanted to confirm the opinion here of xenacanthus

Im starting to catalogue the fossils by genus with grid references, geological data etc

Im also looking on my maps to see if there may be other areas with this same lower westphalean -A coal measure marine band shale locally , Ill keep you up to date with any new finds
