Dinosauria — SceUdosatcrus, etc. 



19 



A large plated Dinosaur has been dis- 

 covered in a tolerably perfect state, and is 

 placed in a glazed case in tlie centre of the 

 Reptile gallery. 



It was obtained from the Lower Lias of 

 Lyme Regis, Dorset, and is a fairly complete 

 skeleton of an herbivorous Dinosaur about 12 

 feet in length, closely allied by its dentition to 

 Iguanodon, and described by Sir Richard Owen 

 as SceUdosatirtis Harrisyni. This reptile was 

 armed with lateral rows of thick bony scutes or 

 spines on each side, which extended along the 

 tail also. There is very considerable disparity 

 between the fore and hind-limbs, as in so many 

 other Dinosaurs. There are four functional toes and one 

 rudimentary one on the hind foot ; the fore-foot is not well 

 preserved and the number of digits cannot consequently be 

 clearly made out in the hand.

Fig. 22. — Restored skeleton of Scelidosaurus Harrisoni (Owen), greatly reduced, from 

 the Lower Lias of Charmouth, Dorset. The figure shows the large lateral dermal 

 spines on the shoulders, and the long lateral line of smaller spines, reaching from the 

 pectoral region to the extremity of the tail ; also the numerous ossified tendons 

 running along the sides of the dorsal spines of the vertebrae from the shoulder to the 

 tail. (The original specimen is about 12 feet in length.) 



. Acantho- 



A smaller Dinosaur, named AcanthopJiolis, found in the Lower pholis. 

 Chalk of Dover, was also armed with spines, but only a few Table-case, 

 fragmentary remains of it are preserved in the collection.
