Word History Take a little deception, add a little excitement, stir them with a century-long mistake, and you have the mystery of the brontosaurus. Specifically, you have the mystery of its name. For 100 years this 70-foot-long, 30-ton vegetarian giant had two names. This case of double identity began in 1877, when bones of a large dinosaur were discovered. The creature was dubbed apatosaurus, a name that meant "deceptive lizard" or "unreal lizard." Two years later, bones of a larger dinosaur were found, and in all the excitement, scientists named it brontosaurus or "thunder lizard." This name stuck until scientists decided it was all a mistake—the two sets of bones actually belonged to the same type of dinosaur. Since it is a rule in taxonomy that the first name given to a newly discovered organism is the one that must be used, scientists have had to use the term apatosaurus. But "thunder lizard" had found a lot of popular appeal, and many people still prefer to call the beast brontosaurus.

Similarly, in "Abrupt Extinctions at the End of the Cretaceous," we are ostensibly allowed insight into the demise of the brontosaurs, as the saurian narrator kicks off the story with the anticlimactic explanation for the extinction, "We were tired.
