Abstract
A careful survey of the dinosaur footprints and trackways (identified as Eubrontes, Anchisauripus and Grallator) at the Mt. Tom site north of Holyoke, Massachusetts, and plots of their orientations reveal that an improbable percentage (70%) of the tracks are oriented in a nearparallel course. All but one of these coincident ancient traverses were probably made by the same kind of Triassic dinosaur (the footprints of which are referred to as Eubrontes). Comparable trackway orientation patterns have been reported by Albritton (1942) near Comanche, Texas for an Early Cretaceous dinosaur (iguanodobntid?) and Bird (1941, 1944) cited paralled sauporod trackways of Early Cretaceous age near the Paluxy River in Texas. Probability dictates that these sub-parallel traverses were not independent events and the presence of other deviating trackways at all three sites indicates that the trackmakers probably were not confined in their passage by physical barriers. Furthermore, the coincidental occurrence of such natural barriers at all of the sites mentioned here seems highly improbable. the combinedevidence of the Massachusetts site and the two Texas localities, together with the apparently widespread occurrence of dinosaur trackway lineation, strongly indicates gregarious habits for several different kinds of dinosaurs.
