Brontosaurus is one of the most well known dinosaurs, but did it really exist? At this point, scientists can't agree on whether Brontosaurus actually existed, as the original type specimen was actually a combination of two different dinosaurs - an Apatosaurus  body and a Camarasaurus  head. Currently, Brontosaurus is not a valid species, but that may change.

When it was discovered that the head of Camarasaurus  was placed on the body of Apatosaurus  and called Brontosaurus, most people thought that was the end of this dinosaur that had become an icon for dinosaur fans from the late 19th century through the 1970s. That may not be the case, however, as Dr. Robert Bakker is developing evidence that supports his claim that Brontosaurus should still be recognized as a real dinosaur. He asserts that it was a huge, long-necked plant eater that deserved its name, which means Thunder Lizard.
