Tyrannosaur teeth variations

Recommended Posts

MedicineHat

My son found a long skinny tyrannosaur tooth on South Saskatchewan River, West of Medicine Hat (oldman formation? Formost FM? DPP?)

 

We've found all sorts of tyrannosaur teeth - short fat ones, short wide narrow ones, long fat ones, long narrow ones (Richadoestia), and all sorts of variations of curves or straight

 

Species, age, and tooth position may all be factors.

 

I'm just wondering if anyone has more info?

 

This tooth is relatively narrow and thin for its length.

 

I can post other examples of teeth found in the same area that are quite different from one another.

 

I believe these may be examples of gorgosaurus or daspletosaurus as they were found in the DPP formation

I can't distinguish between tyrannosaur teeth but someone else might. That's a cool tooth though, it looks like from the pictures it has nice serrations. Also is albertosaurus found their, its often compared to the two tyrannosaurs you listed.

The base is peanut shaped on this tooth but many tyrannosaur teeth are oval at the basal cross section...anybody know why?

Another example of a similar tooth. Relatively long, even for a dentary tooth. It was found on a. Sask. River valley west of medicine hat

No. Not tyrannosaurus rex. Probably gorgo or daspletosaurus

Is there any enamel wrinkles?  And what’s the serration count on both sides over 2mm?

If it is from the DPF then it’s most likely Gorgosaurus as the tool has a DSDI in the range of Gorgosaurus and the wrinkles don’t seem to match that of some Daspletosaurus teeth.  BTW amazing tooth!!

Awesome!!  If it’s Oldman then it’s Gorgosaurus still, nice to see you back on the forum!
