Dreadnoughtus maybe wasn’t as dreadful as original estimates suggested
One of the world’s heaviest dinosaurs may be getting demoted to a lower weight class.
Dreadnoughtus schrani, an herbivore known for its record-breaking mass of 59,300 kilograms, probably weighed only about half as much, scientists conclude in a new analysis published online June 9 in Biology Letters.
The famous dinosaur may have been a little bit bigger than Apatosaurus — but not much, says study coauthor Karl Bates, a biologist at the University of Liverpool in England.
“It’s not the sort of game-changing massive difference that it was built up to be,” he says.
Last year, paleontologist Kenneth Lacovara of Drexel University in Philadelphia and colleagues estimated Dreadnoughtus’ mass by plugging thigh and arm bone
