These massive dinosaurs would have numbered about 20,000 alive at once, but a 2021 study estimated some 2.5 billion in total lived in the late Cretaceous, according to USA Today’s Natalie Neysa Alund. The carnivores ate other animals, carcasses and even each other. The “king of dinosaurs” stood 12 feet tall, grew to 40 feet long and weighed between 5.5 and 8 tons. The bones in Trinity date to around 67 million years ago, when T. rex had 60 teeth, each eight inches long, which it used to munch on flesh (though a recent study suggests these teeth may have been concealed by lizard-like lips). The skull, which is all from the same specimen, is 4.5 by 3.9 feet, according to Koller. Still, Trinity is an impressive sight to behold: Made of 293 bones, the dinosaur stands 12.8 feet tall without its base, and the skeleton spans 38 feet in length. The skull bones all come from the same specimen, and the skull is 4.5 by 3.9 feet in size. Original bone material comprises just over 50 percent of the skeleton-the rest is made from plaster and epoxy resin casts, writes the AFP.Īuction house director Cyril Koller stands in front of Trinity's skull. “It could be that it was a composite-that could be why the purists didn’t go for it,” Karl Green, the auction house’s marketing director, tells the AP. Researchers dug up the bones from fossil sites in the Hell Creek and Lance Creek formations in Montana and Wyoming between 20, according to Koller’s catalog. Trinity is not made of bones from one dinosaur-it’s a combination of parts from three specimens, which could be part of the reason why the skeleton didn’t sell for as much as expected. And some experts thought it was worth more: In March, Christian Link, who is in charge of natural history memorabilia at Koller, told the Agence France-Presse (AFP) that he considered the catalog’s valuation a “very low estimate.” rex, dubbed “Trinity,” brought in less money than the auction house expected-prior to the sale, it had valued the skeleton between $5.4 million and $8.6 million.
