Bone-bed was formed. Where it rested upon the Keuper 
Marls, masses of that rock were derived, rolled, and 
included in the bed,while in other places 
the vertebrate-remains were washed 
into cracks in the marls. But in those 
areas where lakes existed at the time 
the Rhztic Ocean gained access to the 
British inland-sea, there, and there only, 
is the sequence complete from the one 
series to the other. In such cases an 
admixture of sediment would be pro- 
bable, such as is the case at Penarth. 
The reason why the subject of the 
pre-Rhezetic flexuring has been entered 
into somewhat fully is to show that it 
is highly probable that earth-move-. 
ments were at work very early in the 
Mesozoic Era, causing flexures so as to 
suggest that the forces acted from 
north-east and south-west. 
Above the Rhetic Rocks, as will be 
‘\. seen upon referring to figure I, is the 
\ Lower Lias, which caps Berrow Hill. 
Now since there are unmistakable signs 
of earth-movements (the effects of 
which were to bend the strata into 
slight anticlines and synclines, in the 
' epoch during which the Inferior Oolite 
"was deposited), and there are also sug- 
gestions of analogous phenomena in 
Fi immediate pre-Rhetic times, it will be 
z "seen that the Keuper Rocks must. 
be much affected, for they have been disturbed by every 
movement since their formation. And with a range of 
hills composed of Archean Rocks, such as the Malverns,
