![]() "But that technique only works if you have a very complete skeleton (better for Sue than Scotty). You could create a 3D scan of the dinosaur's entire skeleton and model the flesh over it. "You could try making a scale model of what you think the dinosaur looked like in the flesh, directly calculate the mass of your model, and then scale your calculation up. "There are many different approaches to estimating dinosaur size," Dr Persons explains. Longer dinosaurs weren't always heavier than shorter ones. (That's around two-and-a-half times the weight of a white rhino – the largest rhinoceros.)īut again, by factoring in a degree of scientific leeway, Scotty may not have outweighed Sue by a significant amount. The research estimates that Scotty weighed in the region of 8,870 kg (19,555 lb), around 410 kg (900 lb) heavier than Sue, which would make it the most massive T. Advertisementsįrom what we can tell, Scotty was probably slightly longer – perhaps up to 13 m (42 ft 7 in), according to the University of Alberta's Dr W Scott Persons, who led a study into calculating Scotty's dimensions.īut scientists always allow a margin of error when comparing such ancient skeletons, and it's likely that it may not have been demonstrably longer or taller than Sue. That also makes it possible to calculate this dinosaur's original size – 12.5 m (41 ft) long and 4 m (13 ft) tall at the hip – fairly precisely. rex skeleton – comprising 250 of the 380 bones that the body would have featured. ![]() Sue is approximately 90% complete, compared to 65% for Scotty – indeed, Sue is the most complete T. Unfortunately, it's practically impossible to make a direct comparison, as the two specimens are not equally whole. On 4 October 1997, Sue's skeleton sold at auction for $8.3 million (£5.1 million) to The Field Museum in Chicago, Illinois, USA, becoming the most expensive dinosaur bones. It was uncovered in South Dakota, USA, on 12 August 1990, by explorer and fossil collector Sue Hendrickson, after whom it was named. rex skeleton known to science was that of "Sue". They were found in 1991, by then-school teacher Robert Gebhardt, but were so deeply encased in sandstone that it has taken decades to painstakingly remove them. In fact, these bones had been unearthed decades before. Was its skeleton the largest of its kind ever discovered?ĭubbed "Scotty", the skeleton had been discovered in Saskatchewan, Canada. ![]() ![]() In 2015, Cage returned to Mongolia the skull of a Tyrannosaurus bataar dinosaur that he purchased for $276,000 after it was found to have been stolen.In March 2019, a Tyrannosaurus rex made headlines 66 million years after it had died. Some critics have raised concerns that rising prices at auction have fueled demand for the stealing and trafficking of skeletons. Private collectors acquiring fossils could also keep the bones hidden away from the public and from being studied by experts. The sale of dinosaur bones to private collectors has been condemned by scientists, who say museums and research facilities can’t compete with the sky-high prices of specimens at auction. Well-known dinosaur collectors reportedly include actors Nicolas Cage, Russell Crowe and Leonardo DiCaprio. Demand has particularly picked up over the past few years, with a skeleton of the dinosaur that served as a prototype for Jurassic Park’s Velociraptor selling for $12.4 million in May and a 70 million-year-old skeleton of the dinosaur Gorgosaurus fetching $6.1 million in July. Since the first dinosaur ever sold at auction, a tyrannosaur called Sue, fetched $8.36 million in 1997, fossils have sold for sky-high prices. Maximus is believed to be 76 million years old, Sotheby's said.
