There's no reason the theropod identification would be dubious.  It's
typically theropod (laterally compressed, recurved, serrated on both
carinae) and moreover, has anterior serrations much smaller than posterior
serrations.  This is only known in some eumaniraptorans (Achillobator,
Deinonychus, Velociraptor, Saurornitholestes, Bambiraptor, Sinornithosaurus)
and Eotyrannus.
