Another weird Hell Creek Theropod Tooth T-Rex? Dakotaraptor?

[jikohr]

Hi everyone!

 

I recently acquired this from the Hell Creek of Carter County. I assumed it was a juvie Rex and but was asked to check the serration density and it came back weird so I thought I'd ask for some input. I'm hoping I can at least rule out Nano which I will be shocked if this even has the possibility of being Nano. We might be looking at another "Larsonraptor" situation (if you know you know).

CH is 26 mm

CBL is 11 mm

CBW is 8.18 mm

mesial serration density is 14 for 4 mm

distal serration density is 10.5 for 4 mm

DSDI is 4/3

Any insight is appreciated as always!

Agree, Dentary T rex.  Look at the chisel shaped denticles

Thanks guys!

Wish I could discern the denticle shape on something like this. Does high DSDI even become a consideration? Perhaps not on small teeth?
