Fast. Intelligent. Deadly. The "Raptor" is perhaps one of the most famous dinosaur today thanks to Jurassic Park. To many people's surprise however, raptors are heavily feathered and nimbler than movies would have you believe. The Jurassic Park Velociraptor was merely the size of coyote in real life! In fact, their proper family name is 'Dromaeosaurid'. The largest species was Utahraptor, and it grew to the size of a grizzly bear! Dromaeosaurid fossils have been found all over the world. They first appeared during the Cretaceous, though isolated teeth have been found in the mid-Jurassic. Allow me to present my humble collection of Dromaeosaurid teeth.

 

First up, from Cloverly Formation, one of my pride and joy from @hxmendoza

A dromaeosaurid from Aguja Formation. I am seeing more Aguja fossils showing up, but dromaeosaurid teeth are still rare.

Now, for the dromaeosaurids from the famous Hell Creek Formation. Some of them probably lived alongside T. rex. A big shout-out for @Troodon for getting me started on dromaeosaurids with this very first Acheroraptor!

Continuing with USA raptors, we have the classic Dromaeosaurus from Judith River Formation

A rarely-seen Two Medicine Formation dromaeosaurid:

A Canadian dromaeosaurid:

Finally, the good ol' Moroccan raptor. Take note that dromaeosaurids aren't officially described in the Kem Kem Beds, and that specimen #2 and #3 could very well be indeterminate theropods.

Opalised fossils are the best: a wonderful mix between paleontology and mineralogy!

 

Q. Where do dinosaurs study?

Great stuff  Andy happy to see your growing Dromaeosaurid  collection.    Hopefully some day soon we can put some closure to those teeth from the Kem Kem

Thanks Frank. Hopefully in the next decade or so, we will get our answers.

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.

I use a standard DSLR camera with zoom, and I further sharpen the pictures with Photoshop. Your best bet is to use a camera with macro lens.
