Episode notes
Tyrannosaur bite forces and the "Jurassic Park generation" kick off a massive 2-part interview with Dr. François Therrien, Curator of Dinosaur Palaeoecology at the Royal Tyrrell Museum. We separate Hollywood fiction from fossil fact, exploring why the 1993 classic changed the public's perception of dinosaurs from cold-blooded lizards to dynamic, warm-blooded predators.
Dr. Therrien breaks down the complex taxonomy of the Tyrannosauridae family, explaining how Gorgosaurus and Albertosaurus lived, hunted, and were preserved in the Badlands of Alberta.
Topics
Jurassic Park vs. Reality: T-Rex couldn't actually run 50 mph and why its stereoscopic vision means standing still wouldn't save you.
Clades and Naming: Cladistics and the Linnaean classification system, from Coelurosauria to Tyrannosaurus rex.
Dinosaur Provincial Park: ranks in the top five places on Earth for finding complete skeletons.
Bone Histology: Growth rings in fossilized limbs showed some "new species" were juvenile known dinosaurs.
Bite Force Champion: T-Rex's bite—15 times stronger than a modern alligator.
