Pathological shark tooth

Hey,

I purchased a large grouping of shark teeth a couple days ago, and it got here today. I was sorting them, and found a couple interesting ones, this was one of them. It’s very pathological, but I can’t ID it, I think it’s either a false tiger or cow shark, but I can’t tell. @Al Dente @digit @MarcoSr. TIA

I think that may be a cow shark upper tooth. The root looks like it to me, plus the angle of the serrations on the right side of the cusp in the second photo.

Agreed. The beveled root that tapers to a thin edge at the base suggests a cow shark to me as well. I haven't seen a lot of these teeth in person but it does match the look of the ones I've seen.

 

Cool tooth.

 

 

Cheers.

Wow... I’ve never seen a patho cow, definitely not what I we expecting to get!
I was leaning towards cow, but wasn’t sure. Thank you!

I agree that the tooth is a cow shark upper tooth.

Hi,

 

I suppose cow shark is Hexanchidae.

 

Coco

Not sure... @MarcoSr or @Al Dente could probably give you a better answer.

Hi Coco,

 

Yes, "cow shark" is a common name for genera in the Hexanchidae.  I think it's because these sharks, or at least a couple of them, have blunt noses.  Some species have more than one common name in English depending on the area they are occasionally caught.

Hi Marco Sr.,

 

Does it look to you to be pathological or just worn/weathered?

Hi,

 

Thanks Jess, that’s what I thought, but with vernacular names I’m never sure because, as you say, there are several names and it’s the same thing with us.


It doesn't seem pathological to me, it is for me the third superior tooth after the symphyseal one because we see the remains of denticles on each side, but it is very worn out.

The tooth doesn't look pathological to me either, just worn/weathered.

Common names of sharks can vary greatly in different parts of the world and sharks can even have multiple common names in the same country.  It is always best to use scientific names like "Hexanchidae" for a family instead of "cow shark" to avoid any confusion.

I’m not positive that it’s pathological, but looking at the sides of the tooth it looks to thick and seems to have an unnatural curve to it.
