Carnivore maybe Dire Wolf?

[timhigg]

I'm don't know about this.  What do you think?

 

 

Thanks in advance.

Worn mammal tooth?

Geological setting?

@tbr yes, I would say dire wolf but @Harry Pristis @Shellseeker @Bone Daddy  should be able to give a more positive I.D, great find

It looks like it was found in a river or the ocean in Florida(you can tell by the layer of stuff over the tooth)

[Harry Pristis]

The significant measurements of such a tooth are length  and width of the crown.  I think it is a canid, probably a dire wolf.

Yes, on the beach near Jensen Florida.

 

Looks much like Harry's pictures.  I thought it might have a broken crown, but it looks like his with one side lower.

[timhigg]

The measurements match Harry's well.

 

Crown length is maybe just a touch under 1.5 inches.  The width is about right too.

 

Thanks all.

 

I think I mentioned it came from a beach near Jensen Florida.

I just found another tooth that looks like it might be a Dire Wolf too.  Both were beach finds near Jensen Florida, but I know they weren't found at the same time because I distinctly remember finding one of them very much alone near the water line.  Don't remember when I found the other.   Here are pictures of the new one.

This is a P4, an upper carnassial from a canid, perhaps a dire wolf.

 

In canids such as Canis latrans, the upper carnassials (the large pointy cheek tooth) are the fourth premolars (P4). The lower carnassial teeth are the first molar (m1).

 

It's easy usually to distinguish between canid upper and lower carnassials. The upper carnassial (P4) in canids has three roots (or "fangs" as they are called in some books). The lower carnassial - the molar - has only two roots.

 

These coyote upper carnassials have a crown length of about 0.8" or ~20.3mm.

 

Other canid P4 crown lengths are:

For 50 dogs, C. familiaris, the avg. length was . . . . . . . . . . . . 19.28mm

For 111 female coyotes, C. latrans, the avg. lngth. was . . . . . . 19.60mm

For 166 male coyotes, the average length was . . . . . . . . . . . . . . . . 20.38mm

For 12 eastern female gray wolves, C. lupus, the avg. was . . . . 22.67mm

For 19 eastern male gray wolves, the avg. P4 length was . . . . . . . . . . 24.55mm

For a good number of dire wolves, C. dirus, the crown length. . . . 30-35mm

Very helpful.  Thanks much.
