Welcome to Saturday. I promised another new feature today, and here it is! One of my primary focus points on the T.rex Road Trip blog was to keep up on the science and advances, not only in Tyrannosaur research but dinosaurs as a whole. While I have posted some of the papers in the past, I have had the idea for a while that I wanted to add more structure. So, I am pleased to introduce Science Saturdays! Most Saturdays going forward, I am going to make a short post to provide links and summary info for some of the articles that I have found most interesting for the week. I'll also try to go back and put up links for some older papers that I still find relevant or would like to revisit. I hope it's of use to everyone!
Juvenile Intermediate Tyranosauroid Brain Case: First up is a not yet peer-reviewed preview on PeerJ from Chase Brownstein entitled "Prootic anatomy of a juvenile tyrannosauroid from New Jersey and its implications for the morphology and evolution of the tyrannosauroid braincase." It details the finding of the braincase of a juvenile early tyrannosauroid, similar to Dryptosaurus and Appalachiasaurus, that was discovered in New Jersey. Citation and link are Brownstein CD. (2018) Prootic anatomy of a juvenile tyrannosauroid from New Jersey and its implications for the morphology and evolution of the tyrannosauroid braincase. PeerJ Preprints 6:e26467v1 https://doi.org/10.7287/peerj.preprints.26467v1.
Evolution of Tail Weapons: Two weeks ago, the Royal Society published some ground-breaking research by Victoria Arbour and Lindsay Zanno regarding the evolution of tail weapons in avian dinosaurs, and discussing why the defensive adaptations of dinosaurs like Stegosaurus and Ankylosaurus didn't continue developing into present day species. A summary can be found on the New York Times' website, https://www.nytimes.com/2018/01/16/science/tails-weapons-dinosaurs.html. The article also has a link to the paper, "The Evolution of Tail Weapons in Amniotes" by Arbour and Zanno, Published 17 January 2018.DOI: 10.1098/rspb.2017.2299.
Tyrannosaur Evolution and Cretaceous Oceans: This is one from the archives, and an interesting article that uses Trannosaur evolution as a tool to track ocean shores during the late cretaceous. Published in 2013, it's an interesting read. Here's the citation from PLoS One: Loewen MA, Irmis RB, Sertich JJW, Currie PJ, Sampson SD (2013) Tyrant Dinosaur Evolution Tracks the Rise and Fall of Late Cretaceous Oceans. PLoS ONE 8(11): e79420. https://doi.org/10.1371/journal.pone.0079420
