of shore direction and, becoming confused, gone into the deeper 

 waters and drowned. We may also assume, since the strand 

 line repeatedly rose and fell, as is indicated by the changing 

 character of the strata, that large land masses were separated 

 into islands and that these were finally submerged beneath the 

 sea with all the life upon them " (57-9). 



In conclusion : 



" We may picture to ourselves as follows the wonderfully 

 varied life that dwelt along the strand of this Cretaceous sea. 

 Here trod those dull-witted giants whose necks were more than 

 12 meters long and up to 2 meters thick, with length of legs 

 exceeding any known size ; here hurried about the dragon- 

 tribe, large and small, down to the tiniest lizard ; here appeared 

 herds of armored dinosaurs, terrible in shape, with mighty 

 spines along the back and tail ; here hastened past small swift 

 saurians erect upon their hind legs, while others flew through 

 the air ; here were the fearsome flesh-feeding robbers and the 

 Gigantosaurians who alone because of their size could escape 

 living from them and who fed their huge bodies upon plants 

 and smaller sea animals. Scarcely can the noble and prolific 

 animal life of Africa today compare in diversity with that 

 assemblage which here lies before us " (59).
