Acheroraptor 2nd premax

@Troodon

I suppose this is the one-decade-later version of the same tooth I posted earlier?

 

• Hell Creek formation, Garfield co, Montana
• CH: 12.7mm
• CBL: 7.2mm
• CBW: 3.5mm
• Mesial serration density: 8/mm
• Distal serration density: about 4/mm

 

 

 

 

 

 

 

Thanks!

It's certainly a premaxillary tooth of a Dromaeosaurid.  We have nothing to compare against it in the HC to assign it to any specific Dromaeosaurid and nothing has been described.  It's can be best identified as a Indet Dromaeosaurid or cf Saurornitholestes.

Unrelated to this tooth, in the JRf, did Dromaeosaurus have a premax like this too? Or only Saurornitholestes?
