"Because of the scarcity of fossils in sandstones, the ages of these stones are difficult to determine except by the fossil bearing rocks either above or below them. Consequently, sandstones, even of the same area, are often separated and correlated with difficulty. It is for this reason that an effort is made to determine a means by which each sandstone may be identified"--Introduction, page 1.
