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.
Do dinosaurs have 2 legs?
