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.

Carcharocles megalodon shark tooth, with serrations and polished tooth enamel. 208 grams, 11.3 cm



From a Lincolnshire, UK, collection.

Carcharodon megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on the structuring of marine communities. Fossil remains indicate that this giant shark reached a length of more than 16 metres (52 ft) and also affirm that it had a cosmopolitan distribution. Scientists suggest that in life it looked like a stockier version of the great white shark, Carcharodon carcharias.
