stratum. The unconformity reported is at least not of the same order 

 as the unconformity between the Tejon and Martinez, as the structural 

 and faunal break between these two groups is a great one. A very 

 large number of Martinez species failed to bridge the gap. Such is 

 not the case in the vicinity of Domengine Creek. The writer believes 

 that the time break represented by this unconformity is at most of 

 secondary order, ie., such as might separate two formations within a 

 group.
