Pathetic vestigial organ or integral part of fearsome predator?

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.

The truth about T. rex

Even one of the best known dinosaurs has kept some secrets. Here is what palaeontologists most want to know about the famous tyrant.

United States of America v. One Tyrannosaurus Bataar Skeleton

"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."

"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.

"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."
