Direct from the Cretaceous, weighing in at approximately five tons, the tyrant of Larimidia, competing to be the one, the only, American Ninja Warrior, it's TTTTTTTTTTTTTT REX!
A tyrannosaur of one’s own. by Laurie Gwen Shapiro [Aeon] Dinosaur collecting isn't just for museums any more — film stars and sheikhs do it too. What drives a man to covet big bones?
The world’s most famous palaeontologist doesn’t understand why anyone wants to collect dinosaurs. Mark Norell sits across from me in his expansive corner office at the American Museum of Natural History in New York City and launches right in: ‘People are weird. I think: “Who is buying this shit?” No accounting for people’s taste. I have a passion for dinosaurs, but certainly not what I would call “dinosaur insanity”. Dinosaurs are just a medium for me to do science. But if I were doing the same thing on some other organism – you wouldn’t be here.’
In this paper, we examine a first-year torque and angular acceleration problem to address a possible use of the forelimbs of Tyrannosaurus rex. A 1/40th-scale model is brought to the classroom to introduce the students to the quandary: given that the forelimbs of T. rex were too short to reach its mouth, what function did the forelimbs serve? This issue crosses several scientific disciplines including paleontology, ecology, and physics, making it a great starting point for thinking “outside the box..." Lipkin and Carpenter have suggested that the forelimbs were used to hold a struggling victim (which had not been dispatched with the first bite) while the final, lethal bite was applied. If that is the case, then the forelimbs must be capable of large angular accelerations α in order to grab the animal attempting to escape. The concepts of the typical first-year physics course are sufficient to test this hypothesis... Naturally, student love solving any problem related to Tyrannosaurus rex.
Even one of the best known dinosaurs has kept some secrets. Here is what palaeontologists most want to know about the famous tyrant.
"One thing I was wondering is if any of these paleontologists you’ve talked to have given their argument of why paleontology is important." Fossils are "just basically rocks," he said. "It's not like antiquities, where it's somebody's heritage and culture and all that."Bones of Contention: A Florida man's curious trade in Mongolian dinosaurs. [previously]
"If we could build a fourteen-foot-tall alien queen, we’d be able to build a twenty-foot-tall T-rex"
"The sale of this next lot will be contingent on a satisfactory resolution of a court proceeding dealing with this matter."
On May 20th, the fossil remains of a Tarbosaurus (aka, Tyrannosaurus bataar) were sold for $1,052,500. The auction was carried out despite objections from the President of Mongolia and a court order. The problem? The remains may have been poached.

No Leftovers for Tyrannosaurus Rex: New Evidence That T. Rex Was Hunter, Not Scavenger [Full text] [more inside]
"Like many paleontologists, I believe that T. rex was a hunter: a forest hunter. More specifically, I believe that T. rex used the very same hunting strategy that millions of forest hunters practice today: stand hunting from a tree."
Put down that McChicken sandwich, punk, and back away slowly. OK, now run! The chicken is T. Rex's closest known living relative.
