"Peter is an incredibly rare and visually stunning obsidian black in colour," said Dr John Nudds, of the University of Manchester, another of the report authors. Peter's skeleton has a distinct special feature - it has taken on a black colour from organic material that surrounded it as it lay in the Earth.
"We are fortunate in having a significant number of Peter's largest bones, many of which are incredibly well-preserved."
That means his bones have been fossilised, and subject to tens of millions of years of erosion, compression and movement within the Earth.īy bone density, Peter the T rex is 47 percent complete and is "one of the top 10 most complete T rex in the world," said Dr David Burnham of the University of Kansas, one of the report's authors. Tyrannosaurus rex lived between 66 and 67 million years ago, paleontologists said in a report prepared about Peter's skeleton. Peter the T rex was found in 2018 in a fossil-rich area called the Lance formation, near Wyoming in the western United States. The giant fossil is on display until 4 September, and alongside it the museum will run an immersive dinosaur performance, junior palaeontology programme and two other educational programmes on dinosaurs and fossils. Peter is one of about 32 adult T rex skeletons to ever be discovered. So it looks like together they finished him off." " can tell from the spacing of the teeth. "It looks like he was probably killed by another T rex, possibly a mother and a baby T rex, 'cause there's evidence of feeding from a large animal and a smaller animal, but still a T rex. The first-named fossil specimen which can be attributed to Tyrannosaurus rex consists of two partial vertebrae (one of which has been lost) found by Edward Drinker Cope in 1892. His legs were gnawed on by something big. Museum spokesperson Timothy Hart said Peter met a grim end in life. It is the first time this T rex skeleton has been displayed anywhere, and the first time real T rex fossils have been shown in New Zealand. The skeleton is from an adult T rex, and is set up in hunting position, 4m-high and 12m-long. Museum-goers will have the chance to stand up close to one of history's most notorious predators from 15 April.
