Dinosaurs: Four Legs Good, Two Legs Bad
Abstract
Summary. The quadrupedal Sauropods - the biggest dinosaurs to walk the Earth - evolved from bipedal ancestors. Two new early sauropodomorphs from South Africa and Argentina indicate that very large, flexed-limbed sauropodomorphs coexisted with early columnar-limbed sauropods for 20 million years.
