===Original description===<br />
The Creal Springs Limestone Member of the Spoon Formation (Kosanke et al., 1960, p. 32, 64, 65).<br />
<br />
===Derivation===<br />
Named for Creal Springs, Williamson County.<br />
<br />
===Other names===<br />
<br />
===History&#47;background===<br />
<br />
==Type section==<br />
<br />
===Type location===<br />
The type section consists of exposures in the sandstone quarry east of Creal Springs (NE SE SE 25, 10S-3E).<br />

==Stratigraphic relationships==<br />
In the type area the Creal Springs lies on the Granger Sandstone, but throughout much of its extent it is separated from the underlying Murphysboro Coal by several feet of gray shale.<br />
<br />
==Extent and thickness==<br />
The Creal Springs is lenticular and occurs sporadically in a large part of southern Illinois.<br />
<br />
==Lithology==<br />
The Creal Springs Limestone is gray, argillaceous, and in places cherty. It is seldom over 2 feet thick and contains an open-marine fauna.<br />

==Age and correlation==<br />
In some places it was once correlated with the Curlew Limestone, but the fusulinids it contains indicate it is younger than the Curlew (Thompson et al., 1959).<br />
