This is a genuine fossil dinosaur tooth from a Deltadromeus agilis. This rare dinosaur tooth displays light colors and is complete with visible serrations and sharp tip showing light natural feeding wear from when the dinosaur was once alive.
While to date, a skull has not been found of this dinosaur, the recent scientific relation of the species to Ceratosaurs, has been in line what we have been saying for years in our comparison and attributing teeth we sell, to this species. The teeth of this Deltadromeus are notably different from Carcharodontosaurus. The teeth from Deltadromeus very much resemble a massive dromaeosaur. They are much more laterally compressed than Carcharodontosaurus. The side profile of the lateral and anterior teeth are notably taller, with less of a backward dagger-like curvature, than Carcharodontosaurus teeth, where the cross-section is more robust and with a greater hook to the dagger-shape of the crown. Comparison of teeth that we attribute to Deltadromeus, compare very closely to Ceratosaurus sp..
Many fossil dealers have been selling small (1 inch and less in length) Dromaeosaur teeth as teeth of Deltadromeus for much higher prices than they would fetch if there were correctly attributed to Dromaeosaur. Despite a head never being found with the Deltadromeus skeleton, Deltadromeus was a ceratosaur and we do know what ceratosaur teeth should look like. The shape and size of these dealer mislabeled teeth are wrong for this dinosaur. You don't have to have a doctorate in paleontology to understand that a 25 foot meat-eating theropod the size of a juvenile T. rex did NOT have teeth slightly larger than a dime!!
