EARLY DINOSAURS Preserved in a 19-ton slab of limestone in the Hall of Early Dinosaurs is mute evi- dence of what may have been a fight to the death between two giants of another era. First are the tracks made by a gigan- tic brontosaur as it slogged through its prehistoric swamp habitat in what is now Texas. Since there is no impression of a dragging tail, the beast was probably wading in shallow water, looking for the vegetation on which it fed. Alongside, and in two instances super- imposed on the brontosaur tracks, are the characteristic three-toed tracks of a carnivorous allosaur. Reconstructed skeletons of these extinct beasts give the visitor some idea of what must have hap- pened if, as the trackway seems to show, the allosaur was stalking its larger, but more clumsy and less ferocious, prey. Other exhibits show transition stages from amphibians to the first reptiles, in- cluding some reptiles that were ancestral to mammals, others that evolved into the dinosaurs. One wall case contains a photographic account of how well-preserved dinosaur skeletons were collected in New Mexico in the late 1940's. Another display illus- trates special adaptations in feeding, de- fense, and locomotion among dinosaurs living in different habitats.
