Hi guys,

             I recently made a trade with someone for some theropod teeth fragments from Alberta, I was just wondering if their was any chance of possibly nailing down what these teeth came from other then theropod.

As always many thanks guys,

What size are the fragments and do you have any better locality than Alberta.  That province covers many ages and types of theropod dinosaurs.

The fragments are all approximately 1-3cm, as far as she was aware they only came out of Alberta so I don't the exact providence but ill try and find out she's more of a crocodile person so may have more stuff for me in the future :P

The serrations look like Tyrannosaurid fragments especially the larger pieces.  If you can get a better understanding of the locality we might be able to do better.

There's Foremost Formation, Oldman Formation, Dinosaur Park Formation, Scollard Formation, Horseshoe Canyon Formation, Milk River Formation just to name a few. You will need better locality info.

 

As Troodon said, they do look Tyrannosaurid.

Having spoken to the original owner she has told me they come from the dinosaur park formation itself and the locality was the dinosaur provincial park

Great so you are looking at either a Daspletosaurus or Gorgosaurus.  Try doing a serration count over 5mm might tells us more

The ones that are greater than 15 fit the range for Gorgosaurus so although not positive it's possible.  The others can go to either tyranno
