Merced formation—The Merced formation, so remarkably devel- 
oped at Sevenmile Beach, south of Lake Merced, only a few miles 
north of the Santa Cruz quadrangle, is barely represented on the 
latter. Certain limited fossiliferous outcrops, however, yield a fauna 
sunilar to that of the typical Merced and have therefore been corre- 
lated with it. The most important of these localities are just south of 
the mouth of Ano Nuevo Creek, near Felt Lake, and in the sea cliffs 
between Santa Cruz and Capitola. The following species of fossils 
have been found in the Merced outcrops above indicated :
