Rare dog tooth

Recommended Posts

b. bartron

I found a rare tooth from my local miocene exposure in calvert county md. Found along the choptank formation. Believed to be carnivorous dog. But not positive. Any help with a confirmed id would be appreciated

The tooth appears to be a canid M2, but I am not aware of a land mammal element in the Miocene Choptank Fm.

I think they are known to be found, but less common.

Calvert Marine Museum might be able to help.

Unfortunately its rare enough that Mr. Godfrey wasn't familiar with the species either. Canid m2 left side is as far as it goes so far. It spent a lengthy time at the Smithsonian in d.c also.....

So new species? Or just too difficult to ID with certainty?

Mr Nance and Mr. Godfrey have examined it. But it's nothing common from our exposure.

Its possible that its new. Or its likely that its just very uncommon to find in our locality and may just be an update to the range. Im an amateur so im pretty much clueless.

And here is your opportunity to work with some of the professionals and not only absorb some knowledge from them but represent all us avocational fossil hunters by strengthening the cooperation with those that have made a career in paleontology. I've always enjoyed my encounters with the geologists, coral reef scientists, marine taxonomists, and paleontologists I've had the privilege to work with on projects. It's very exciting to find a rarity that stumps the experts. Keep us informed and let us know how this plays out.

 

 

Cheers.

The tooth better resembles the canid example, doesn't it.

the only thing ive found similar is bear dog. The difference is they are larger and the root structure  is straighter where as mine is half the size and one root has a hook shape to it. The nature of the bite seems the same . Having a grinding edge and a cutting edge. im considering different options on what to do with the tooth at the moment.  A positive id would be great. But do i really just want to donate it for the purposes of study? Ive donated a fair amount of stuff. And I'll admit i kinda regreat the rare thing i have already let go of. So. Im stuck with wanting to and not wanting to equally.  

Its not the collectors fault than science demands ownership for scientific purpose.  And if it turns out that the 3d imaging will solve the issue and backup collection finds for study than id be totally down to lend it for that process. I hope the project works out and we have a way around the issue.

I don't think this tooth is from an amphicyonid.

I was suggesting it as it is the first thing that pops into my head when someone says “canid” at Calvert.
