Sorry, Fred

There’s no such thing as a brontosaurus. Eager to claim a new species during the competitive “bone wars” of the 1870s, Yale paleontologist Othniel Marsh slapped a mismatched skull, tail and feet onto an incomplete apatosaurus skeleton he’d found in Wyoming.
Amazingly, the error persisted until 1975, leaving a confusing slew of brontosaurus references on everything from postage stamps to Flintstones reruns. Don’t believe them.
