The Late Jurassic epoch, which started 161.2 million years ago and ended 145.5 million years ago is a time in Earth's history when the main predators were the newly-evolved carnosaurian theropods. At this time tyrannosaurs never got any larger than 10 feet (3 meters) long. The main herbivores in this environment were the plate-backed stegosaurians and the long-necked and gigantic sauropods. The diplodocoid sauropods were the ones that thrived the most. These include Diplodocus, Apatosaurus (formerly called "Brontosaurus") and Supersaurus (see left).
It is believed, by some, that the asteroid 298 Baptistina may of played a role in the J-K (Jurassic-Cretaceous) extinction .
