Investigating T. Rex's Bite
In Investigating T. Rex’s Bite, scientists explore the strength of the dinosaur’s bite using a pressure sensor and a crocodile. This video is excerpted from BBC's Horizon: T. Rex, Warrior or Wimp?, a documentary featuring interviews with T. rex experts from around the world and exploring the science behind the legend of the dinosaur we love to hate.
Horizon tells amazing science stories, unravels mysteries and reveals worlds you've never seen before. Learn more.
Lesson Express
Q: What are some similarities between T. rex and a crocodile?
A: The teeth, bite strength, predatory behavior, and limb structure are similar.
Q: What animals, still alive today, are similar to extinct animals that you could study to compare and contrast with T. rex?
A: Some animals that are still alive today that are similar to extinct animals are crocodiles, alligators, and sharks.
Q: What is the importance of a pressure sensor and what are some other ways it could be used beyond checking for the strength of a crocodile bite?
A: A pressure sensor can measure the amount of force or pressure that’s applied to something. In the clip, the sensor helped the scientists measure the amount of force of the crocodile bite. Other uses of pressure sensors include medical devices, weather, and cars.

After the dinosaurs dominated Earth for millions of years, their enormous size became a disadvantage when a catastrophic extinction changed the planet. This clip from BBC’s Evolution episode "The Elephant" follows the small, adaptable ancestors of elephants as they survive in the aftermath, when being tiny, flexible, and able to eat a wide range of foods becomes a major evolutionary advantage.
The video also explores one of the challenges these early mammals faced as plant eaters: digesting tough cellulose. Their solution was a partnership with microbes living in their guts, which can break down plant material that the animals cannot digest on their own. This symbiotic relationship helped early afrotherians thrive and spread into the habitats left open after the dinosaurs disappeared.
