Big Picture Science - The T-Rex Files
T-Rex is having an
identity crisis. Rocking the world of paleontology is the claim that Rex was
not one species, but actually three. It’s not the first time that this
particular dino has forced us to revise our understanding of the past. The
discovery of the first T-Rex fossil in the 19th century taught humanity a
scary
lesson: species eventually go extinct. If it happened to this seemingly
invincible apex predator, it could happen to us too.
Hear how the amateur
fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of
ourselves, and the epilogue to the dinosaur era: how our mammalian relatives
survived the potential extinction bottleneck of an asteroid impact.
