358 NON-SEQUENCE BETWEEN KEUPER AND EH^TIC. [Aug. I904, 



those localities where the distribution of the infra -Bone -Bed 

 deposits indicates elevation of the Keuper Marls in immediate pre- 

 Rhaetic times, it is noticeable that there is a non-sequence at the 

 base of the Lias. At Sedbury Cliff, a locality where the Keuper 

 Marls were not wholly submerged until Bone-Bed times, a bed of 

 conglomerate separates the basal Liassic deposits from the Rhaetic ; 

 at Lassingtou there is a remanie-bed ; and in Warwickshire — in a 

 region affected by the movements along the Pennine-Moreton anti- 

 clinal axis — the ' Guinea-Bed ' points to a non-sequence. Indeed, 

 to quote Mr. H. B. Woodward, near Church Lawford 



* It is not improbable .... that there was some irregular overlap of the 

 Rhtetic Beds, accompanied by reconstruction of some layers, during the 

 changing conditions that ushered in the Lower Lias.' x
