DICKERSOK— FAUNA OF THE TYPE TEJON 



49 



It will be seen from this description that Locality 183 is 

 stratigraphically lower than Locality 182. The stratigraphy 

 around Vader is evidently not so simple as Martin's descrip- 

 tion quoted above might lead one to infer. ^Martin states that 

 the strata at locality 184, another Tejon locality on Olequah 

 Creek one mile north of Vader have a strike of N. 35° W. and 

 a dip of 60° E. A plot of these localities about Vader shows 

 that some faulting or acute folding has taken place between 

 localities 184 and 182.
