phant. It was impossible from these to form any idea of its general 

 appearance. . In 1880, however, several complete skeletons were found 

 in Belgium and restored 

 by Dollo. From these it 

 is learned that the animal 

 certainly walked on its 

 hind-legs, using its power- 

 ful tail also as a support ; 

 also that the anterior part 

 of its jaws was toothless 

 and covered with horn, so 

 as to form a nipping-beak 

 like a turtle's. Fig. 693 is 

 a restoration by De Pauw. 

 The Megalosaur was 

 a somewhat smaller but 

 probably a more formida- 

 ble carnivorous reptile, 



which lived through the whole Jurassic period. Its huge jaws were 

 armed with large, curved, flattened, saber-like teeth. A femur has been 

 found forty-two inches long (Phillips), and a tibia 

 thirty-six inches. The animal was at least thirty feet 

 long (Owen). Fig. 694 is a restoration of the head of 

 this animal by Phillips, and Fig. 695 is a restoration 



of the skeleton of 

 the Scelidosaurus, 

 an animal allied to 

 the Megalosaur. 

 The Megalosaurs 

 also were bipedal. 



The Ceteosaur 



(whale-lizard) was 



the largest reptile

larger have been found in the Jurassic of the United States. It has 

 been classed among the Crocodilians, but Prof. Phillips has shown that 

 its true position is among the Dinosaurs. A thigh-bone has been found 

 sixty-four inches long, 27*5 inches in circumference at the shaft, forty- 

 six inches and 44-25 inches in circumference at the two ends respect- 

 ively (Fig. 696). According to Phillips, the animal was at least fifty 

 feet long, ten feet high when standing, and of bulk proportionate. It 

 was probably like the Iguanodon a vegetable feeder. 



The HylcBOsaur was another huge reptile of the same period, and
