Etymology: Megalosaurus was named in 1824 by the Oxford geologist William Buckland, who based the name on a partial lower jaw found in a quarry near Stonesfield, Oxfordshire. It was the first dinosaur to be formally named in a scientific paper, and the name was built entirely from Ancient Greek: "mégas" meaning "large" and "saûros" meaning "lizard." Buckland's choice made the name a literal description of a giant lizard, even though the animal was later understood to be a dinosaur rather than a reptile of the ordinary kind. The "mégas" element traces back to a very old Indo-European root meaning "great," which passed into Ancient Greek and became the standard combining form for "large" in scientific coinages. "Saûros" was the ordinary Greek word for lizard, and it appears in many later dinosaur names as the suffix "-saurus." Together the two parts follow the pattern that taxonomists used for naming new animals in the early nineteenth century, when Greek and Latin roots were the preferred material for scientific vocabulary.
