Notorynchus cepedianus 

“blue site” Beaufort Co. SC? 

 

A long lost land site that was south of Charleston. Known for its off white and baby blue hues sometimes with a hint of blue grey and yellow. I believe it may of been near the May river. Supposedly it was flooded due to a hurricane.

Wow, didn't know this thread existed! Beautiful teeth!  Wish I had found before!

I'll show some fanciful Notorynchus cepedianus "middlesexi" (my county in Virginia) cow shark bottom laterals, which I have been obsessed with lately. 

I recently started hunting a spot where I had never found much, but seemed to find a bottom lateral cow shark tooth every second or third trip, almost all in good condition. 

I recently found (and posted) what has been referred to as a "pathological" bottom lateral (even called a pathosymphysial-lateral).

Yesterday I found a second one (top right).  I have found about ten bottom laterals there, and the odds of finding TWO pathological teeth out of ten or so seem very low. Particularly since I had never come across one at my other spots.  I have found lots of pieces, (although the collection is biased; only single teeth with the characteristic serrations were counted as cow shark --of course multiple spikes on broken pieces also counted.  Need to look for broken "patho" laterals also but more fun to hunt outside for new stuff).

Doubt you could claim a new species/ subspecies on the basis of a few teeth, but generally the cow shark teeth look slightly different in the new spot.  Maybe my imagination but the serrations on several seem "fused".  The majority of intact teeth in the photos came from that same spot (the two with the deepest roots I think I bought; maybe mixed with the ones I found (?)  I have seen other people hunting there (even now in winter); so need to ask if they have found any of the "pathological" teeth (most can see much better than me, they may have symphysials also.  Unfortunately most just hunt "shark teeth", but they are very friendly).  Meanwhile I'll keep hunting hard.

Keeping with the theme of Cretaceous Hornby island…

 

Protoheptranchias lowei 

Northumberland Fm

Hornby Island, British Columbia, Canada

 

may be a Hexanchus microdon as well but this is the info that came with it

My opinion is not that of an expert Paul, but that looks like a VERY good match to the symphyseal of P. lowei in the paper that described it. I went back and checked the paper a minute ago so not going off memory lol

Great tooth and if it were mine, I’d feel really comfortable with that ID.

I always have a hard time when it comes to the symphyseal. Plus Protoheptranchias and heptranchias are new to me as well. 
 

Appreciate the vote of confidence in ID!

Here is a picture of my cow shark teeth collection. The second tooth is a German Notorynchus (I believe Bremen area). And the last picture is of my rarest cow shark tooth, a Heptranchias tooth from Poland.

Funny thing is, I was thinking about starting this chat a few weeks ago, I wasn't aware one existed already!

From the VA miocene

Splendid in-situ imagery!
