Episode 12: Growing up Dinosaur

Past Time

When we think of iconic dinosaurs, like T. rex with its massive head full of teeth, and Parasaurolophus crowned with a gigantic, tube-like horn, we’re thinking of the features of adult dinosaurs. But we know from looking around today that animals change a lot from birth to adulthood. Did T. rex always have a massive maw and Parasaurolophus a huge crest? How quickly did they grow in? What were they used for? To really understand the biology of these titans, paleontologists need to study baby dinosaurs to connect the dots from tiny hatchling to adult dinosaur. Unfortunately, the fossils of dino-toddlers are few and far between because their skeletons are usually pretty delicate. In this episode we discuss the improbable discovery of a baby Parasaurolophus with Dr. Andy Farke, a paleontologist from the Raymond Alf Museum and Webb Schools in Clermont, California. Dubbed “Dinosaur Joe”, the young dinosaur was found and studied by young, high school scientists from the Webb School. The high school scientists were part of the team that revealed the six-foot-long animal was only one-year-old and had a little nubbin of a what would become that spectacular Parasaurolophus crest.
