1914] English: The Fernando Group near Newhall, California 209 



SAN FERNANDO VALLEY 



Beds of the Fernando group are structurally continuous from the 

 Santa Snsana Range and the region of Elsmere Canon into the San 

 Fernando Valley, where they flank the south side of the granitic mass 

 of the San Gabriel Range. Northeast of the town of San Fernando 

 are small areas of diatomaceous shale which occupy the peculiar 

 position of being next to the edge of the valley and separated from 

 the granite by the presumably younger Fernando gravels. The fol- 

 lowing forms were found east of Little Tejunga Creek 8 in a coarse 

 sandstone of the Fernando :

FAUNA OF THE LOWER FERNANDO 



The Fernando group includes beds of diverse lithology and of 

 different ages, which probably belong to more than one formation, 

 though the recognition of any stratigraphic divisions within the group 

 awaits more detailed areal mapping than has yet been done. However, 

 the faunas from different localities may be expected to show some- 

 thing of the relationships and indicate possible separations within this 

 succession of beds. 



The fossils of the following list are from Elsmere and Holser 

 canons, with a smaller collection from Pico Canon, the species from 

 the San Fernando Valley not being included.
