The neck was long and flexible, and, considering its proportions, was the lightest portion of the verte- bral column. The body was short, and the abdominal cavity of mod- erate size. The legs and feet were massive and the bones all solid. The feet were plantigrade, and each footprint must have been about a square yard in extent. The tail was large and nearly all the bones are solid. The diminutive head will first attract attention, as it is smaller in proportion to the body than in any vertebrate hitherto known. The entire skull is less in diameter or actual weight than the fourth or fifth cervical vertebra. A careful estimate of the size of Brontosaurus, as here restored, shows that when living the animal must have weighed more than 20 tons. The very small head and brain, and the slender neural cord, indicate a stupid, slow-moving reptile. The beast without offensive or defensive weapons or dermal armature. 21 23
