Preprint Published: A Tyrannosauroid Metatarsus from the Merchantville Formation of Delaware increases the diversity of non-Tyrannosaurid Tyrannosauroids on Appalachia

Hello everyone. Recently, I have worked on describing several tyrannosaur specimens from the Cretaceous Formations of Atlantic Coastal Plain. One of the manuscripts I have written concerns a partial tyrannosaur metatarsus from the Merchantville Formation of Delaware. As of now, the preprint of this paper has been published, and you can find it here:

The metatarsus represents a distinct morphotype of tyrannosaur from Dryptosaurus or Appalachiosaurus, but nevertheless is too incomplete and lacking in distinguishing features to warrant the naming of a new specimen. Certainly, the diversity of tyrannosauroids on Appalachia has been underestimated.
