fossil_lover_2277 posted a topic in Fossil Hunting TripsTyrannosaur tooth I found in North Carolina's Black Creek group yesterday afternoon. Based on the serration count, I'm thinking it's Dryptosaurus, the line of serrations in the second pic is 1.58cm long (measuring by hand), and I counted 31..I do plan to check them for certain later with a stereoscope, but my understanding is Dryptosaurus has <11 serrations/0.5cm and Appalachiosaurus >11/0.5cm. If anyone who deals with this regularly wants to help with the ID, please feel free.
AlexSciChannel posted a topic in DocumentsA new paper by Chase Brownstein published today describes two new taxa from the Merchantville Formation of Delaware and New Jersey. A new tyrannosauroid of which metatarsal material was previously described here: https://doi.org/10.7717/peerj.4123 this time a new recovered vert was collected from the same locality likely belonging to the same individual. This thorough analysis of metatarsalian material has given the prescedent to return the tyrannosaur family known as Dryptosauridae which includes Dryptosaurus aquilunguis and the Merchantville taxon. Also described is a new H
AlexSciChannel posted a topic in General Fossil DiscussionWhat is the most likely attributable identity for the Tyrannosauroid remains at Phoebus Landing of the Tar Heel Formation? What I am referring to specifically are bones documented in Baird and Horner's 1979 paper which speaks of a distal third of a right femur that is attributed to cf. Dryptosaurus and is smaller than the holotype of D. aquilunguis. It is also compared with Albertosaurus which shows similarities as well but that's expected with Eutyrannosaurs. Also there is another distal left femur of a tyrannosauroid shown to be found in a Hypsibema bonebed and origi
