Kristi Curry Rogers, Paleontologist: How Dinosaurs Grow

Kristi Curry Rogers wants to understand how dinosaurs got to their gigantic sizes. As a paleontologist she looks for fossilized dinosaur bones and then analyzes the bone tissue to see how fast the animal grew. Like tree-rings, bones show a record of growth rate. Curry Rogers discovered that unlike modern reptiles, dinosaurs grew quickly, an evolutionary advantage for young dinosaurs living amongst huge predators.
