ONLINE ETYMOLOGY DICTIONARY:

tyrannosaurus (n.)

carnivorous Cretaceous bipedal dinosaur, 1905, Modern Latin genus name, coined by H.F. Osborn (published 1906 in "Bulletin of the American Museum of Natural History" XXI, p.259) from Gk. tyrannos "tyrant" (see tyrant) + -saurus. Abbreviated name T. rex attested by 1970 (apparently first as the band name).

tyrant (n.)

c.1300, "absolute ruler," from O.Fr. tyrant (12c.), from L. tyrannus "lord, master, tyrant" (cf. Sp. tirano, It. tiranno), from Gk. tyrannos "lord, master, sovereign, absolute ruler," a loan-word from a language of Asia Minor (probably Lydian); cf. Etruscan Turan "mistress, lady" (surname of Venus).

In the exact sense, a tyrant is an individual who arrogates to himself the royal authority without having a right to it. This is how the Greeks understood the word 'tyrant': they applied it indifferently to good and bad princes whose authority was not legitimate. [Rousseau, "The Social Contract"]

The spelling with -t arose in Old French by analogy with prp. endings in -ant. Fem. form tyranness is recorded from 1590 (Spenser); cf. M.L. tyrannissa (late 14c.).

-saurus

element used in forming dinosaur names, Latinized from Gk. sauros "lizard," of unknown origin; possibly related to saulos "twisting, wavering."
