The items described above are those that are most needed and constitute
the basic equipment of the fossil hunter. The serious amateur may wish
to include certain additional items which will place his collecting on a
more professional basis. Some of these accessory items are:
1. A _topographic map_ of the collecting area. These are available for
many parts of the State and are published and distributed at nominal
cost by the United States Geological Survey, Washington, D. C., and/or
Denver, Colorado. The Survey can supply an index sheet showing all such
maps available for Texas.
2. A _geologic map_ of the collecting area if one is available. The list
of publications of the Bureau of Economic Geology should be consulted to
see if a geologic report or map of the area has been published. This
list may be obtained without charge from the Bureau of Economic Geology,
The University of Texas, Austin 12, Texas.
3. The _geologic map of Texas_. Although a geologic map of Texas is
included in this publication (Pl. 10), the scale is so small that its
use is somewhat limited. For more detailed work a larger geologic map in
color (scale: 1 inch = 31.56 miles) may be ordered from the Bureau. The
sale price is 25 cents.
