A MONOGRAPH 
OP A 
FOSSIL DINOSAUK 
{SCELIDOSJimUS HABMSOmi, Owen) 
OP THE 
LOWER LIAS. 
In the year 1858 a few fragmentary fossils of limb-bones were submitted 
to my inspection by James Harrison, Esq., of Charmouth, Dorsetshire, obtained 
from the upper part of the “ lower Lias,” near that place. They included portions 
of a femur and of a tibia, in which the texture of the wall and the size of the 
cavity of the shaft showed them to have been parts of a Saurian of more terres- 
trial habits than any of those which had been previously discovered in Liassic 
deposits : traces, moreover, of the extent and direction of certain processes, although 
broken away in the fossils, were discernible, which led me to suspect they 
belonged to a reptile allied to Igiianodon. I therefore briefly notified the fact 
of a Liassic Dinosaur in my ‘ Palaeontology,’''^ and indicated the animal by the 
generic name Scelidosaurus.^' I propose, in the present monograph, to describe 
these very interesting fossils as they have successively come under my observation, 
and submit the proofs of the generic distinction and Dinosaurian affinities of the 
extinct animal.
