^ The Cerro Pelado series, which is considered by Kugler to be Aquitanian, is 

 placed by Liddle (31, composite geologic column for Venezuela) in the lower 

 Miocene. Vaughan (48, p. 704) states: ". . . . and there has been difference 

 of opinion as to whether the Aquitanian should be classified as Oligocene or 

 Miocene."
