There can be little doubt that the fossil iferous beds in this section 
e on very nearly the same horizons as those in the section west of 
lalone station. 
The most prolific locality for Malone Jurassic fossils, and the only 
ne not directly connected with the mountain itself, is in the low 
ills in the valley about 1^ miles east of Malone station. The 
sposures are comparatively small and the dips variable, so that the 
ratigraphic details either as to thickness or succession can not be 
etermined with certainty. Professor Cragin gives his observations 
n this locality fully in another place (pp. 13-17). 
It is not possible to make a definite correlation of the fossiliferous 
ds here with any single horizon in the Malone Mountain sections, 
ut it is most probable that they belong not more than 300 feet 
3ove the main gypsum beds. 
At this point the Malone Jurassic beds are closer to fossiliferous 
retaceous beds of determined horizon than at any other place 
^served in the region. About 3 miles to the east, near the south- 
est base of Sierra Blanca, there are exposures of Washita beds with 
odosaria texana and Gryphcea mueronata (?), and the same hori- 
)n occurs a little farther away along the railroad between Etholen 
ills and Quitman Mountains. 
Mr. Taff correlated portions of the Malone Mountain section with 
.posures in the conical hills near Etholen about 5 miles west of 
° Mr. Taff assigned these gypsum exposures, as well as those at the southeast end of the 
cmntain, to a higher horizon (see pp. 725 and 736 of his report), but they all have the 
me relations to the fossiliferous horizon hearing the Malone fauna.
