Name Origin

The Bogota Limestone Member of the Mattoon Formation (Newton and Weller, 1937, p. 9) is named for Bogota, Jasper County.

Type Section

The type section consists of exposures along Big Muddy Creek about 6 miles southwest of Bogota (NE NE 7, 5N-8E) (Kosanke et al., 1960, p. 44, 79, 80).

Extent and Thickness

The Bogota is known definitely only in the type locality, but the name has been questionably applied to many limestone outcrops in the central part of the area of the Mattoon Formation.

Description

In the type section the Bogota is 1.5 feet of gray, fossiliferous, nodular limestone in a yellowish brown clay matrix, and it overlies about 1 foot of black fissile shale.
