Mississippian Thing


TNCollector

Recommended Posts

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.

 

Bangor Limestone

Mississippian (Late Carboniferous)

East TN

Size of about 0.75cm

I don't think so, Dave:

The picture makes this item look pyritized.  Is this the case?

No it is not pyritized. The lighting I had on it gave it a yellowish tint.

It kinda looks like a jaw!!! But, not sure!!! :headscratch:

It is quite strange. 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.

It looks similar to Venustodus. Venustodus has the same raised rim and similar cusps. 

All Dente got it! Thanks for the help!

 

Yet another new genus to add to the list of this locality.
