one-fourth natural size. 
Description . The type (Plate IV, Figure 1, and Figure 6) shows very 
good outline, but no phalangial pads. All the toes are very broad and end 
in bluntly pointed hoofs. Digits II and IV are strongly divergent, point 
outward at their distal ends, but are free for only about one-half of their 
length. The proximal portions of the toes were doubtless enclosed in a 
pad or web. In the type, digit III is more deeply impressed than the 
others, but in the paratype the three toes seem to have carried the weight 
about equally. Digit III is broadest near the distal extremity, whereas 
the others taper gradually. In the type, a poorly preserved second track 
indicated a stride of 915 mm., or slightly more than three times the length 
of the track. In the paratype, the length of the stride relative to the length 
of the tracks is slightly greater. The tracks are almost in a straight line, 
but point slightly outward from the line of march.
