Nathan Myhrvold, the Microsoft millionaire who went on to found Intellectual Ventures, is a huge dinosaur geek. But not just any dinosaur geek: He funds paleontological digs, gets heavily involved in research and keeps a life-size T. rex skeleton in his living room. Now he and other scientists have built a quarter-scale dinosaur tail to show that giant sauropods really could snap their tails at supersonic speeds.
Myhrvold and University of Alberta paleontologist Philip Currie first made that claim 18 years ago, based on computer modeling. But their hand-operated contraption – a 44-pound tail section that’s assembled from 3D-printed vertebrae and tipped with a bullwhip popper – provides an ear-splitting demonstration of the effect.
“Personally, I think one of the most interesting aspects of this is the process of using physical simulations to try to ascertain the behavior of extinct animals,” Dhileep Sivam, a bioinformatics specialist who works at Intellectual Ventures, said in an email.
