Definition
(n. pl.) An order of extinct mesozoic reptiles mostly of large size (whence the name). Notwithstanding their size they present birdlike characters in the skeleton esp. in the pelvis and hind limbs. Some walked on their three-toed hind feet thus producing the large bird tracks so-called of mesozoic sandstones; others were five-toed and quadrupedal.
