VERY unusual tooth

[Dino Dad 81]

Hey all,

 

This looks Dromaeosaurus to me, but we'll have to see if it's even possible to make that call without any posterior serrations. But the dramatic mesial twist that happens close to the tip and the general morphology give me hope.

 

Also, curious to know what your take is on the posterior edge. The posterior serrations seem to have been sliced off. The serration-like indentations inside the slice itself look a little like they might come from the serrations of another individual's tooth (i.e., face biting or something similar). This tooth got seriously used!

 

• JRf, Hill co, Montana
• CH: 12mm
• CBL: 6mm
• CBW: 3mm
• Mesial serration density: about 4/mm
• Distal serration density: POSSIBLY similar, based on what might be traces

No idea what it is but very nice tooth.

The base cross-section does not inspire one's to say its Dromaeosaurus.   The tooth just looks odd because a portion has been broken off, most typically post mortem but who knows.  Difficult to make a call on a partial 12 mm tooth with key characteristics missing.. I would label it as indeterminate.

@Dino Dad 81 I don't know an exact ID either, but still it's a pretty intact tooth! Great Job!!

Hi @Troodon,

 

I don't mean to pest at all, but I want to make sure it was clear which grooves I was referring to. There's such consistency in the spacing...

If it was already clear, apologies for the follow up.

The way I see it those are two edges with the fractured face
