482 Woodworth— Dinosaur tracks in New Jersey. 
1. Three foot-prints about 8 inches long; stride from toe to 
toe of 1 and 2 about 19 inches; from toe to toe of 2 and 3, 
about 81 inches. The tracks resemble the form named 
Anomepus major by Edw. Hitcheock, the print embracing 
the impression of the foot together with that of the lower part 
of the tarso-metatarsus, which latter would make the prolonged, 
indefinitely-ending, heel-like projection wherever the animal 
crouched upon the beach.* If this explanation be applicable 
in this case, the foot proper has a length of about 5 inches. 
2. Three-toed prints from 2°5 to 3 inches long, digital 
impressions jointed ; one line of these prints contained five dis- 
tinct tracks, with a stride of about one foot. The second line 
of tracks was similar, with six prints. 
A heart-shaped impression about four inches on a side and 
sharply defined was seen on another slab. A similar impres- 
sion, in the Amherst collection, is in a relation to foot-prints to 
indicate that it was made by an animal crouching on the beach. 
Other vague impressions, due to the moulding of the bottom 
as if by the rolling contact of a flexible, wrinkled body, are 
probably to be explained as made by dinosaurs in a recumbent 
position. Long straight and curved furrows also exist both at 
Avondale and on the track layers in the Newark quarries. 
So far as one can judge from tracks, these impressions afford 
nothing not already known in the Connecticut area. Their 
existence in the section which has been taken for the type of 
the Jura-Trias basins along the Atlantic coast, is of importance 
as serving to remove the criticism which has been made against 
the revival of Redfield’s term,—the Newark group,—that the 
characteristic fossil tracks of the better known Connecticut 
area do not occur in it. 
I am indebted to my friend, Prof. Geo. C. Sonn, of Newark, 
N. J., for essaying to have the large slab with fourteen tracks 
preserved in the High School of that city.
