Hell Creek Theropod Claw id help

[jikohr]

Hi everyone!

 

I have my eye on an interesting claw from Hell Creek in Carter County Montana on "that website" and was wondering if anyone could give some extra insight. The seller listed it as Alvarezsaurus, which I had honestly never heard of before, and a quick search revealed that genus is much older than Hell Creek and from South America. I think they might mean it's from the Alvarezsauridae family, but in any event before I try for it I figured I should ask for an outside opinion on what this is from since this group is new to me.

Saw that one too. Trierarchuncus prairiensis is what it looks like.
