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.


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.
