Way back, when scientists were madly digging up and naming dinosaurs, bearded paleontologist Othniel Charles Marsh dug up and named a massive sauropod: the apatosaurus. "Apatosaurus" means "deceptive lizard." Very few people felt the urge to say the name more than once. The dinosaur was a flop.

Professor Marsh soon dug up and named another, similar skeleton: the brontosaurus. “Brontosaurus” means "thunder lizard." This is the sauropod you've heard of.

But trouble was brewing for brontosaurus.  Some guy named Elmer — a hairless man from Kansas — reviewed the two specimens and declared them the same species. Scientists abandoned the second, better name.

Unperturbed, brontosaurus went on to great success, dominating lunch boxes, gas stations and casual conversation for the next hundred years. Meanwhile, dorks everywhere delighted in the opportunity to correct preschoolers on their nomenclature.

In 2015 vindication finally arrived for brontosaurus when a team of smarter, modern scientists confirmed what children and film producers everywhere already knew, BRONTOSAURUS! is a real, fancy creature with great creative instincts, a knack for thriving in unconventional circumstances, and pretty eyes.

In the end, Othniel Charles Marsh was returned to glory. Elmer, meanwhile, is dead.
