The Tyrannosaurus rex had teeth that were serrated like a steak knife, designed to cut through flesh and bone with ease - Jurassic Park

The most famous and iconic of all dinosaur species, the T-rex was first described by Henry Fairfield Osborn in 1905 from a skeleton found in 1902 from the Hell Creek Formation in Montana. Standing over 13ft tall and 40ft long, the T-rex was the top predator of the late Cretaceous, and amongst the last dinosaurs to walk the earth before their mass extinction. The T. rex tooth offers an incredible insight into how these ferocious creatures lived. The tooth, characterized by its unique curved and serrated shape, was specifically adapted to help the dinosaur tear through hides and flesh, with the curvature allowing the T-rex to apply maximum force as it tore into its prey.

This remarkably preserved fossil offers insight into the largest predator to ever walk the Earth. Supreme symbols of ferocity, these fossil fragments represent the most primal and terrifying aspects of prehistoric life: as seen in Michael Crichton’s Jurassic Park where the T. rex’s massive, bone-crushing teeth are central to the narrative’s tension and excitement. The depiction of the T-rex in both the novel and its film adaptation directed by Steven Spielberg, as well as such other notable films like King Kong and Journey to the Center of the Earth, has left a lasting impact on popular culture, emphasizing the sheer power and danger of the ancient predators.
