Thanks. Take note that the just sideview pictures aren't enough. Juvenile tyrannosaurid teeth often bear great resemblance to raptor teeth, and there's also the issue of Moroccan theropods.

 

Serration count, close-ups of denticles, front view, back view, cross section etc are all needed to make a proper diagnosis.

 

This tooth for instance, was assumed to be a Moroccan raptor for a while. It was thin enough, slightly recurved, and even had the correct denticle/5mm count. But it turned out to be an Abelisaurid!

Not sure this tooth is an Abelisaurid, denticles dont look right.  Checked out Richter paper look at E and F Denticles and shape.  they call it Dromaeosaurid.   What do the mesial serrations look like hard to see in your photo.

@Troodon Henry earlier told me it's a Abelisaurid tooth from the dentary position.

Those are better views of the denticles and these look more Abelisaurid than Dromaeosaurid

Those sneaky Abelisaurids. Seems that they account for at least 80% of wrong Dromaeosaurid IDs.
