FAUNAL RELATIONSHIPS OF THE MEGANOS GROUP 153 
for a considerable distance. It would appear that the Tejon beds 
in this last general locality may be delta deposits rather than 
typical marine deposits, such as those to the east in the vicinity 
of Grape Vine Canyon. This is borne out by the paucity of the 
fauna as well as by the lithology. 
Fauna of the type Tejon.—The faunas obtained from different 
horizons in the type section of the Tejon, as found in Grape Vine 
Canyon, were studied by Dickerson. The invertebrate species 
were listed and.a number of new species described by him.t Dick- 
erson’s conclusion, with which the writer agrees, was that the 
fauna obtained from the various horizons in the type Tejon, taken 
as a whole, isa unit. It has already been pointed out that Dicker- 
son believed that these beds were somewhat younger than the 
Turritella andersoni beds at Coalinga or his lower Tejon from 
the south side of Mount Diablo, which beds of both localities are 
referred by the writer to the Meganos. In discussing this fauna, 
he says? 
Beds about three hundred feet above the base (University of California 
locality 458) yielded an excellent fauna. This fauna, however, does not differ 
~ essentially from that of the beds higher in the section. The faunas from 
several other localities which are listed below do not differ materially from one 
another, but appear to represent one phase only. This faunal unity is in 
consonance with the sedimentary record as Anderson described it... .. 
The writer is in complete agreement with Anderson’s view as expressed 
here in relation to the type Tejon. However, beds both higher and lower 
than the Eocene of Canada de las Uvas occur in other parts of the state, notably 
in the vicinity of Mount Diablo, along Cantua Creek, Coalinga Quadrangle, 
and at the Marysville Buttes. 
As quoted in the paragraph above, Dickerson recognized that 
the fauna of the type Tejon was higher than that from the Lower 
Eocene beds on the south side of Mount Diablo, and higher than 
his so-called lower Tejon at Coalinga, the Turritella andersoni 
beds, which latter beds are here referred to the Meganos Group. 
He correlated the fauna of the type Tejon with that of his Rimella
