FOSSIL REPTILE GALLERY. 
remains of the gigantic Dinosauria, which far exceeded in size 
any other land-animals. A mounted plaster cast of a complete 
skeleton of an Iguanodon (fig. 49), found (with many others) 
at Bernissart in Belgium, is 
a conspicuous object in the \ 
middle of the room. The 
original from which it was 
taken is in the Brussels 
Natural History Museum. 
Nearly allied to the gigantic 
Iguanodon is the diminutive 
Sypsilopliodon foxi, of which 
remains are also found in 
the Wealden formation of 
the Isle of Wight. Both 
habitually walked in the up- 
right posture on their three- 
toed hind limbs. In the centre 
of this gallery is placed a large 
portion of the skeleton of a 
gigantic Dinosaur [Cetiosanrus 
leedsi), from the Upper Jurassic 
Oxford Clay near Peter- 
borough. This Dinosaur is 
believed to be nearly allied to 
the North American Diplo- 
doms, of which a restored 
sketch is placed alongside the 
skeleton. Both Cetiosaurus and 
Drplodocvs resembled Bronto- 
saurus{^g. 50) in the extremely 
small size of their skulls. 
At the eastern end of the 
gallery are the Pterosauria or 
Ornithosauria,commonly called 
Pterodactyles or Flying Eep- 
tiles, of which the most gigantic representatives were the 
species of Pteranodon from the Upper Cretaceous of Kansas 
(fig. 51). At the west end is the nearly complete skeleton of
