TERRIBLE REPTILES 87 
The Jurassic strata of North America have yielded 
remains of an even greater Deinosaur in the form of 
the Brontosaurus. It had big feet, which made 
impressions almost a square yard in size, long neck 
and tail, small head, and a short stout body. It 
is said to have been nearly sixty feet long, and to 
have weighed between twenty and thirty tons—not 
at all a nice creature to tread on one’s toes! The 
Stegosaurus (Greek, stegein =to cover, and sauros = 
a lizard), or plated lizard, had a protection of great 
spines and plates along its back, some of the plates 
being nearly three feet across. The 7'yrannosaurus 
(tyrant-lizard) was not so long as the Brontosaurus, 
but certainly he was more powerful. His feet were 
immense—four feet long by three feet wide. A con- 
tributor to Knowledge describes him in these terms : 
‘“ We have every reason for congratulating ourselves 
that Tyrannosaurus rex is not our contemporary. 
He was practically a biped (two-footed animal), with 
an agile birdlike manner of progression, the immense 
feet possessing three enormous toes projecting for- 
ward, and one extending backward, all furnished 
with huge tearing claws. The head is much larger 
than that of the Brontosaur, and the great teeth are 
serrated (sawlike) and sharp-edged.” It is said 
that Tyrannosaurus was the largest flesh-feeding 
animal of which we have any knowledge, and the 
fiercest monster of the Mesozoic Age. 
You would certainly be delighted if you could 
find fossil remains of some of these Deinosaurs. I[ 
cannot promise you that you will do so, even if you 
search for the rest of your lives. I admit that I 
have not found any, but perhaps you may be more
