Where are the baby dinosaurs?

In a spellbinding talk, paleontologist Jack Horner tells the story of how iconoclastic thinking revealed a shocking secret about some of our most beloved dinosaurs.

Many classic dinosaur species are actually just the young or adolescent forms of others, mistaken for adults because of dramatic changes as they grew. Museums collected only the biggest fossils, so baby dinosaurs seemed to vanish. Bone analysis reveals that some dinosaurs, like Triceratops and Pachycephalosaurus, were mislabeled as multiple separate species when they were really just growth stages of the same animal. This discovery rewrites the dinosaur family tree and shrinks the cast of prehistoric giants.
