It could be a Saurornitholestes tooth.

Need 2 more photos...one showing the complete outside edge including carina, straight in shot like 6th photo. And a duplicate of the last one, closer if possible but focus on the denticles.  Want to see the shape of a few complete ones more toward the tip.  I dont think its Saurornitholestes but want to make sure.  Think its Tyrannosaurid.

  Much better denticle pictures though still not seeing the entire mesial edge, however not an issue.

It's a Juvie Tyrannosaurid based on the shape of the denticles
