1921] Frick: Faunas of Bautista Creek and San Timoteo Canon 319 



Occurrence 



As has been mentioned above, the beds lying beyond the two- 

 thousand foot level of the north limb of the San Timoteo fold carry 

 considerably less clay than those lying below. No determinative 

 material has been secured from this sandy region of the crest and it 

 is, therefore, impossible to ascertain whether it contains a more 

 advanced fauna than that of the lower clay beds to which the collect- 

 ing has been almost entirely confined. Fossil remains are uncommon 

 but have been found both in these more or less gritty clay strata, 

 ranging in color through browns, yellows, light blues and greens, and 

 also in the underlying clayey sands and coarser fanglomeratic sands.
