tiary period inclusive down to the present epoch. The phosphatic 
nodules, for which the beds are explored, appear to have had their 
origin from the Eocene rocks beneath. These have also contributed 
numerous remains of marine vertebrates, especially of squalodonts, 
reptiles, and fishes. Mingled in the sand and clay with the phos 
phatic nodules and bones of Eocene animals, are innumerable 
remains of cetaceans, sharks, and other marine animals of perhaps 
the middle and later Tertiary ages. Added to these are multi-
