HISTORICAL GEOLOGY. 



not merely poor luck as to becoming fossilized. The fore limbs were much 

 the shorter pair, as in other species of the groi;p. 



In contrast with the Megalosaurs there was the strongly Bird-like 

 Compsognathus, from Solenhofen, C. longipes of Wagner, one of the smaller 

 Dinosaurs, the length not over two feet. The feet were all three-toed ; the 

 fore limbs very short, the hinder long, Avith the femur shorter than the 

 tibia ; the neck long and slender ; the head small, but well armed with teeth, — 

 characters indicating, as Huxley states, a strong resemblance to the Bird not 

 only in general form, but probably also in an erect or nearly erect posture in 

 walking. It is perhaps related to Hallopus Marsh, of the North American 

 Jurassic.

Mystriosaurus Tiedemanni. 



Among Herbivorous Dinosaurs, of the Sauropod division, the largest 

 European species known was the Cetiosaurus of Owen (1841), related to the 

 American Morosaurus. C. Oxoniensis was 40 or 50 feet long, "not less than 

 10 feet in height when standing, and of a bulk in proportion." The femur 

 is 64 inches long. Cetiosaurian remains occur in the Lower and Upper 

 Oolyte, and five species have been described.

Another genus of gigantic Herbivorous Dinosaurs is the Iguanodon of 

 Mantell, which first appears in the Middle Oolyte ; it was of the Ornithopod 



group.
