===Original description===<br />
The Reisner Limestone Member of the Mattoon Formation (Kosanke et al., 1960, p. 41, 51).<br />
<br />
===Derivation===<br />
Named for Reisner School, Jasper County.<br />
<br />
===Other names===<br />
It previously was called Newton Limestone (Newton and Weller, 1937, p. 9, 24-25).<br />
<br />
===History&#47;background===<br />
<br />
==Type section==<br />
<br />
===Type location===<br />
The type section consists of exposures along West Crooked Creek, 1.5 miles northeast of the abandoned Reisner School (NE NE 16, 7N-10E).<br />

==Stratigraphic relationships==<br />
The Reisner Limestone lies 60-80 feet above the Bogota Limestone Member and 40-45 feet above an unnamed coal that was mined from a few shallow shafts in the vicinity of Newton and was reported to be approximately 2 feet thick. Kosanke et al. (1960) stratigraphically placed the Reisner Limestone as the youngest named member in the Mattoon Formation. However, recent studies indicate that the Reisner Limestone occurs below the Greenup Limestone, as had been stated by Newton and Weller (1937).<br />
<br />
==Extent and thickness==<br />
<br />
==Lithology==<br />
Near its type locality the Reisner Limestone is argillaceous and contains fragments of small brachiopods. It is generally less than 1 foot thick, is overlain by 1.5 feet of black fissile shale, and is underlain by claystone containing argillaceous and generally unfossiliferous (with local exceptions of ''Spirorbis'') limestone as much as 3 feet thick in places.<br />
