I just sent you a PM. Your tooth sure looks like a Lungfish plate to me....WOW.....:faint::faint::faint:    I'm in shock..its been nearly 20 years since I found mine in 98.

I will post the papers about the two lungfish teeth plate that was found ,,mine and one that was found in Maryland shortly,,,,Congrad's Frank.

Wow, that's awesome thanks everyone! @Fossildude19 It's 1.6 inches long by a little over an inch tall so this was a big guy. I will let the local museum know! I'm told this is the second one to come out of New Jersey and third east of the Mississippi so thanks so much for the ID help everyone!

I'm looking at James Kirkland's paper at the moment and I think you have a outside chance that yours maybe a different lungfish then the one I found...its beginning to look like a ....Ceratodus robustus ...maybe... not sure yet. If so that would be a plus to find a different type......Sooooo Cooolllllll......:D

I have been looking at James Kirkland's paper and did some comparison to frank8147 and from what I can make out from some poor photo's and drawings in the paper.... what you may have is a Ceratodus robustus which is from the Upper Jurassic Morrison Fm and to my knowledge is only where they are found in the western interior  and  another possibility that its a very large C. frazieri , C.gustasoni which are both from the Upper cretaceous deposits in the western interior as well.  Even though C.robustus is not known in the Upper Cretaceous in the western interior doesn't mean that they couldn't have survived along the eastern coastal section of North America. C.frazieri certainly did why not another type.   Prior To the discovery of C.frazieri in NJ late Cretaceous deposits they believed the Lungfish died out some 100 million years ago in north america and to find another one,,,,,known from the Jurassic  along the cretaceous coastal plains would be amazing to say the least. I all most forgot to mention about a lungfish tooth plate that was found in 2004 in Marylands late cretaceous deposit around 95 mya it was only a partial section and I have not seen any paper about it....but was worth mentioning. 

 

 

Here is Kirkland and Parris papers

Thanks, I will put it for FFOM later today.

Tony, thanks again for the research papers, this has been really fun to read and research, I'll look more into it tonight. Im also looking very closely at Ceratodus Robustus but as per our discussion, I'll probably be donating this in the very near future so we'll find out for sure soon :-)

Congratulations on an amazing find :wub: :envy:, and kudos for your willingness to donate the specimen for study!   :fistbump:

 

Perhaps our North Carolina/South Carolina/Georgia/Alabama members will keep and eye out for similar specimens, and help fill in the gap between the Texas and New Jersey occurrences.
