== Not purbeck Marble == 

 Apparently the bits at the end of this article are not specifically about the Marble, so why are they here? 

 *"Purbeck stone has been used for restoration and new projects in ecclesiastical buildings throughout England, but especially in the south. For example it is used in the Exeter, Ely, Norwich, Chichester, Salisbury, Lincoln, Llandaff and Southwark Cathedrals and in Westminster Abbey. 
 The pterosaur ichnogenus Pteraichnus is found in the Purbeck Limestone.[7]"
