.52" Raptor Tooth - Montana

This tooth in particular shows morphology similar to that of Richardoestesia isosceles or Paronychodon. The tooth is tall with an isosceles triangle shape and low vertical ridges and more of a D shaped cross section. It is .52" long with beautiful enamel and serrations with very little feeding wear. It comes in an acrylic display case.

Smaller theropods like Velociraptor typically did not use their teeth for killing and so their teeth are much smaller in size in relation to their skulls when compared to larger therapods that used their teeth as the primary killing tool.

Many of the raptor teeth found in the Hell Creek Formation show morphological differences that are often attributed to taxon from other formations of different ages. Among those are Saurornitholestes, Richardoestesia gilmorei, Richardoestesia isosceles, and Paronychodon. Remains of all of these species are fragmentary and some known only from teeth and there is no evidence they lived in the Hell Creek Formation.

The 2013 study found that Acheroraptor was the only dromaeosaurid from the Hell Creek Formation and concluded that dromaeosaurid teeth that had been attributed to other taxa should be identified as Acheroraptor. Any other identification is not supported scientifically until associated skeletal remains are found to indicate otherwise.
