Troodontid?

[Fullux]

Kind of interested in this fossil, says it's a troodon tooth, wanted a second opinion. It's from the hell creek formation.

Pectinodon, I reckon.. but you'll need to post more specific location and size.

Looks like it, such a small chunk though I’d wait to find a more complete one. 

[Troodon]

Fragments are difficult to call since all the diagnostic features are not present.  This looks like a portion of the outside edge of a Troodontid.   The problem calling it a Pectinodon is that they are not dentulated on the mesial, outside, carina.  The shape of the denticles also don't fit cf Troodon but could possibly be from a Premaxillary position. I would call it an indeterminate troodontid
