Strepsodus Posted August 11, 2020 Share Posted August 11, 2020 I found this today in County Durham, UK. It comes from the coal measures (upper Carboniferous). If anyone can identify it that would be great. It measures 55mm long. 1 Link to comment Share on other sites More sharing options...
westcoast Posted August 11, 2020 Share Posted August 11, 2020 Coalified bits of sigillaria bark maybe Link to comment Share on other sites More sharing options...

The same block contains fish teeth and other fish fragments. The lines go around the curve which I dont think could happen in Sigillaria. Link to comment Share on other sites More sharing options...
Petalodus12 Posted August 12, 2020 Share Posted August 12, 2020 I agree that there is coalification going on here, but I also do see bone structure. Not sure what this is to be honest. Hopefully you get an ID! 1 Link to comment Share on other sites More sharing options...

I wonder if it could be some kind of jaw with all the teeth missing? 1 Link to comment Share on other sites More sharing options...

This one is a tough one to ID, for sure 1 Link to comment Share on other sites More sharing options...
Strepsodus Posted August 12, 2020 Author Share Posted August 12, 2020 I think I have figured out what this is. Figure from 'Catalogue of the fossil fishes in the British museum (natural history)'. 2 Link to comment Share on other sites More sharing options...
jdp Posted August 12, 2020 Share Posted August 12, 2020 Not totally sure it's oracanthus, which looks like this: But I'd agree it is probably a gyracanthid of some sort. "Gyracanthus" duplicatus looks a lot like your fossil. 3 Link to comment Share on other sites More sharing options...

Thanks, I have been reading some books and I agree Gyracanthus looks a good match. 1 Link to comment Share on other sites More sharing options...

TqB Posted August 12, 2020 Share Posted August 12, 2020 It's a nice find and "Gyracanthus" looks a good provisional ID. :) 3 Tarquin Link to comment Share on other sites More sharing options...
