DINOSAURS 167 
eagerly look forward. The Brussels Museum now contains ten 
mounted specimens, and twelve more lying in position on the 
rock. There cannot be much doubt that these unarmoured 
Dinosaurs were molested and preyed upon by their carnivorous 
contemporaries, such as the fierce Megalosaurus, previously 
described (p. 134). And with regard to this, M. Dollo 
makes the suggestion that, when on land, their great height and 
erect posture enabled them to descry such enemies a long way 
off. Their great height must also have stood them in good stead, 
by enabling them easily to reach the leaves of trees, tree-ferns, 
cycads, and other forms of vegetable life, which constituted their 
daily food. (See Plate XXIII.) 
Should the reader visit the “geological island” in the grounds 
of the Crystal Palace, he will see that Mr. Waterhouse Hawkins’s 
great model Iguanodon there set up is by no means in accord- 
ance with the description given above; but we must remember 
how imperfect was the material at his command. Mr. Karl 
Hagenbeck has recently added to his famous Zoological 
Gardens at Hamburg a number of life-size models of extinct 
animals, thus following in the footsteps of Mr. Waterhouse 
Hawkins, but with happier results. It is a step in the right 
direction, for the Science of Paleontology has made such great 
strides in the last forty or fifty years that a great deal of light 
has been thrown on the ancestry of living animals, and thus the 
student of life as it is to-day finds himself led back into past 
ages in order to get some.glimpses into the evolution of the 
various orders and families now inhabiting the world. 
Just as the Ceratosaurus of the New World is represented by, 
or rather corresponds to, the Megalosaurus of the Old World, so 
the other newly discovered Dinosaur, which we are about to 
describe, shows a good deal of correspondence with the now
