I was looking at some of my small theropod teeth, but I was not 100% sure what the best ID for these two teeth were. Any input or help would be appreciated. These were sold as Nanotyrannus, but very small chance of dromaeosaurid and Aguja dromaeosaurid respectively, but I think they might be Richardoestesia cf. gilmorei. The cross-section of the Hell Creek tooth I think rules out Dakotaraptor, or at the very least, does not match the known morphology. Edit: Oops, I used the really funky side of the ruler I'm using. I was going to use the millimeter side, but ending up using a side that measures 20mm per. The measurements are accurate though as I used calipers for that. Hell Creek Formation; Garfield County, Montana CBL: 6mm CBW: 2.4mm Mesial Density: 8-9/mm [Towards end of carinae] Distal Density: 11/2mm (5.5/mm) CH is a bit difficult since the tooth has heavy feeding wear, but it is 8.3mm tall, but could be significantly higher. The mesial carinae does not appear to extend to the base. Aguja Formation; Brewster County, Texas CH 6.4mm CBL 3.7mm CBW 1.4mm Mesial Density: Possibly worn down, or none Distal Density: 16/2mm (8/mm)
