Dromaeosaurus Tooth?

[Omnomosaurus]

Hi folks,

 

I've seen a tooth for sale listed as a Dromaeosaurus Albertensis. I trust the seller's ID, but I'm not 100% confident with dromaeosaurs, so would just like to hear what the forum experts think?

 

Locality: Judith River Fm. (Havre, Montana)

 

Size: 2cm

 

These are the only photos, I'm afraid. There is apparently a twist in the mesial carinae, but it's not super clear.

 

 

Thanks in advance, guys!

Unfortunately like Ive indicated many times one cannot look at just photos of most isolated theropod teeth for a proper identification.  Will need to know the serration density of both carina 5mm wide at midline of the carina.  Also a photo of the base is needed.   The Lingual twist is also present on  Tyrannosaurid teeth from the Judith.   Base looks pretty stout for a Dromaeosaurid would lean at this point to a tyrannosaurid.

Thanks, Troodon! I know how impossible it can be to ID isolated teeth from photos like this, but thought I'd see what people's first thoughts were.

 

You do such a fantastic job of identifying teeth, any input is appreciated - it does have a very robust base, now you mention it.

 

I might take a punt & buy this one just to get a better look!

I lean tyrannosaur. However, Dromaeosaurus teeth are more robust than most other dromaeosaurid teeth, but usually not that robust.
