Paleontologists in the US may have discovered the remains of a Thescelosaurus killed at the moment of impact when an Everest-sized asteroid struck the earth and caused the extinction of dinosaurs. It was discovered at the Tanis site in southwestern North Dakota, which researchers believe holds a detailed record of the devastation wrought by the asteroid’s impact 66 million years ago.
The BBC reported the unusual discovery on Thursday, years after obtaining exclusive access to the Tanis site ahead of a forthcoming documentary feature, ‘Dinosaurs, the Final Day’, hosted by Sir David Attenborough.
“This looks like an animal whose leg has simply been ripped off really quickly. There’s no evidence on the leg of disease, there are no obvious pathologies, there’s no trace of the leg being scavenged, such as bite marks or bits of it that are missing,” Professor Paul Barrett of the Natural History Museum in London told the BBC, concluding that he believed it “died more or less instantaneously.”
The team at Tanis says the mix of marine and terrestrial fossils discovered at the site add credence to their belief that they’re working with hard evidence of the catastrophe.
