    • n iguanodon The typical genus of the fossil family Iguanodontidæ: so called from the resemblance of the teeth to those of Iguana. The species, of which several are described, were of gigantic size, some being 30 feet long. They stood up on their hind limbs, which were long and strong in comparison with the fore limbs; the latter were used for prehension rather than for locomotion. The tail was long and heavy, serving to steady the animal in the erect posture and for swimming. The best-preserved specimen, an almost perfect skeleton, is that of I. bernissartensis, found in Belgium, which, as mounted, stands 14 feet high and covers a horizontal line 28 feet long.
    • n iguanodon [lowercase] A species or a specimen of the genus Iguanodon or family Iguanodontidæ. The name is also loosely used for many related reptiles, being thus almost synonymous with dinosaur or dinosaurian.
