Ad ANIMALS OF THE PAST 
as we do, the prints of the toes would have 
been followed by a long heel mark, but such 
is not the case; there are the sharply defined 
marks of the toes and nothing more, showing 
plainly that the Iguanodons walked, like birds, 
on the toes alone. More than this, had these 
Dinosaurs dragged their tails there would have 
been a continuous furrow between the foot- 
prints ; but nothing of this sort is to be found ; 
on the contrary, a fine series of tracks, uncov- 
ered at Hastings, England, made by several 
individuals and running for seventy-five feet,, 
shows footprints only. Hence it may be fairly 
concluded that these great creatures carried 
their tails clear of the ground, as shown in the 
picture of Thespesius, the weight of the tail 
counterbalancing that of the body. Where 
crocodilians or some of the short-limbed Di- 
nosaurs have crept along there is, as we should 
expect, a continuous furrow between the im- 
prints of the feet. This is what footprints tell 
us when their message is read aright; when 
improperly translated they only add to the 
enormous bulk of our ignorance.
