Identification: This tooth was sold as being from a Dromaeosaur. The serrations' shape and their similarity on both carinae say otherwise.

For those who consider Nanotyrannus to be valid, this tooth is still T. rex based on the robustness of the tip and serrations, and the CHR (Crown Height Ratio). Tyrannosaurus maxillary teeth may still have minor basal compression, as this one does. This is from a juvenile animal based on its small

So, this may not be a perfect illustration of purely ontogenetic variation. The adult T. rex denticles are from an unknown position and carina (being from a tooth fragment), the juvenile T. rex denticles are from the distal carina of a right (rear?) maxillary tooth, and the infant T. rex denticles are from the distal carina of a posterior tooth. The Nanotyrannus -
