TNCollector Posted February 15, 2017 Share Posted February 15, 2017 I have been staring at this thing for a while and looking at all of my Paleozoic vertebrate books, but I am officially stumped. It has the color and texture of the typical holocephalan/chondricthyan teeth that I find here, but the morphology is just not matching anything I have seen before. It is possible that it could be a part of a trilobite or some other invert, but I am not very well versed on my invertebrates. Further, the invertebrates are very rarely this color here.

Darktooth Posted February 15, 2017 Share Posted February 15, 2017 The picture makes this item look pyritized. Is this the case? I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

The lighting I had on it gave it a yellowish tint. Link to comment Share on other sites More sharing options...
Ramon Posted February 15, 2017 Share Posted February 15, 2017 It kinda looks like a jaw!!! But, not sure!!! "Without fossils, no one would have ever dreamed that there were successive epochs in the formation of the earth" - Georges Cuvier Link to comment Share on other sites More sharing options...

I don't think it is a jaw, my instinct says tooth of some sort, but it is just a very strange item. There is no evidence of dentine tubules (aka bradydont structure), which are usually present in teeth that would be this sort of shape (such as Ordodus sp.). Also, the circular piece that is kind of whitish in the picture is where there is a missing spike. 2 Link to comment Share on other sites More sharing options...
westcoast Posted February 15, 2017 Share Posted February 15, 2017 Interesting! Looks more like arthropod... Link to comment Share on other sites More sharing options...
Al Dente Posted February 15, 2017 Share Posted February 15, 2017 It looks similar to Venustodus. Venustodus has the same raised rim and similar cusps. 6 Link to comment Share on other sites More sharing options...
