Predator Evidence on Dinosaur bone, teeth marks

[WyomingRocks!]

Hello, I believe this bone shows evidence of teeth scoring from a predator Dinosaur (raptor or other theropod) and I am asking for a confirmation of this. I found this a few days ago in Wyoming in a formation I believe may be the Lance but I am not sure. Teeth there include Archeroraptor, other Dromeausaurid (sp), triceratops, avaceratops, paralbula, myledaphus, hybodus shark, edmontosaurus, borealasucbus, brachychampsus, fish, a couple of mammal types, large theropods, Aublysodon?, lissodon, Ankylosaurid, melvius as the most commonly found specimens. Of course, none are common but just in comparison to other fossils.

Appears to be predation but its impossible to say who cause them.  Gouges are light, one larger, mostly small, no serrate marks probably a theropod but not necessarily one.  Nice specimen

I put this in the wrong thread. It was supposed to be in general discussion.
