Apatosaurus

/əˌpætəˈsɔːrəs/noun

A long-necked, long-tailed sauropod dinosaur of the late Jurassic of North America.

The Greek roots

ἀπάτη
apátē
deceit, trickery
+
σαῦρος
saûros
lizard

Literally: deceptive lizard

The story of the word

Othniel Marsh named it the deceptive lizard in 1877 because a bone in its tail resembled that of a marine reptile and had misled him. Two years later he named another skeleton Brontosaurus, thunder lizard, and it proved to be the same animal, so the older and duller name took precedence. Palaeontologists have argued since 2015 over whether Brontosaurus deserves reinstating as a genus of its own.
