Fossil Tyrannosaurus Rex Dinosaurus Bone
Maastrichtian, Upper Cretaceous, circa 67-65 million years B.P.Estimate: £25 - 35 (+bp*)
Opening Bid: £5
Fragment of bone from Tyrannosaurus Rex, supplied in a display box with an information label. 40 grams total including case, bone: 41 mm
Property of a Bristol, UK, gentleman collector.
The most famous and iconic of all dinosaur species, the Tyrannosaurus rex, was first described by Henry Fairfield Osborn in 1905 from a skeleton found in 1902, in the Hell Creek Formation in Montana. An adult Tyrannosaurus would have weighed almost nine tonnes, standing over 4 meters tall at the hip and exceeding 13 meters in length. It is no wonder this theropod was the top predator of the Late Cretaceous, and amongst the last dinosaurs to walk the Earth before their mass extinction. The present tooth offers an incredible insight into how these ferocious creatures lived, characterised by its unique curved and serrated shape, which was specifically adapted to help the dinosaur tear through hides and flesh, with the curvature allowing maximum force to be applied as it tore into its prey. -
