Diplodocus and the Giant Sauropods
On the timeline · around Late Jurassic, 152–145 million years ago · The Jurassic
What happened
In the Late Jurassic, long-necked sauropods reached enormous sizes. Diplodocus, one of the longest dinosaurs ever known, roamed the Morrison Formation of western North America alongside other giant plant-eaters.
Why it matters
Sauropods were the largest animals ever to live on land. Their immensely long necks let them browse vegetation far out of reach of any other herbivore.
