PALEONTOLOGY OF THE MALONE JURASSIC FORMA 
TION OF TEXAS. 
By F. W. Cragin. 
INTRODUCTION. 
SCOPE OF INVESTIGATION. 
This paper embodies the paleontological and some geological re- 
sults of recent studies in the Jurassic of El Paso County, Tex. It 
is in part the outgrowth of one of briefer scope, prepared in 1897-98 
from collections and data obtained by me in a reconnaissance made in 
1897, and supplemented by some of the results of the earlier work of 
Messrs. Taff, Wyschetzki, and Goodell, as explained below. In its 
present form it includes also the study of two collections made by Dr. 
T. W. Stanton, of the United States Geological Survey, as noted more 
particularly elsewhere herein. 
GEOGRAPHY OF THE REGION. 
In El Paso County, a few miles north of the Rio Grande and 75 to 
80 miles southeast of El Paso, is a narrow ridge known as Malone 
Mountain. Its trend is nearly north-northwest and south-southeast, 
and is nearly continuous with that of the northwestern end of the 
Quitman Mountains, from which it is separated by an interval of less 
than a mile. At the eastern base of the mountain, near its northern 
end, on the joint line of the Southern Pacific and Texas Pacific rail- 
ways is the flag station of Malone, which has an elevation of 4,262 
feet above sea levels Also on this line of railway, and between 2 and 
3 miles west of the north end of Malone Mountain, is Finlay station. 
As shown by the Fort Hancock sheet of the Topographic Atlas of the 
United States, in preparation by the United States Geological Survey, 
the mountain rises to somewhere over 5,050 feet above sea level, and so 
has a relative altitude of about 800 feet. On either side of the moun- 
tain ridge are hills that are geologically related to the mountain.
