Preprint Published: Theropod Specimens from the Navesink Formation

Hi there everyone. I just wanted to note that my preprint on ornithomimosaur and tyrannosauroid hindlimb elements from the Maastrichtian Navesink Formation of Monmouth County, New Jersey, has been published. Recently, the taxon “Teihevenator” was erected by Yun (2017)(it’s a nomen nudum because the Zoobank LSID for the name wasn’t included in the paper and the paper doesn’t seem to publish copies)(for more discussion of this see my preprint on a tyrannosauroid from the Merchantville Formation of Delaware(1) and this post at the Theropod Database Blog). I was also working on these specimens during the time Yun (2017) was published describing AMNH 2550-2553 as a new genus, with myself describing them as a chimaera of ornithomimosaur and tyrannosauroid remains. As such, upon hearing of the publication of Yun (2017), I finished up my figures of the specimens and submitted it for publication as a preprint, which you can find here. I love hearing from all of you, so please don’t hesitate to leave comments on this post or on the preprint itself regarding the manuscript!

Thanks again for reading!

Footnotes-

(1) The metatarsals II and IV are from Delaware. Though I only named the state of discovery of these specimens twice incorrectly in the manuscript, I made an error and for some odd reason thought the specimens were found several miles east of Summit Bridge. This error has been corrected in my working copy of the manuscript and I have addressed it by adding an erratum in the comments section of the manuscript.

 

 

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.
