Summary:

Pg. 7, 13, 22, 37. Meadow limestone member of Braddyville formation. First distinct limestone member of Braddyville formation above Forbes limestone. Has wide distribution in Nebraska and apparently in Kansas and Missouri. Is usually in one bed, but in places is in 2 beds. Light bluish gray, massive, hard, semicrystalline; upper part weathers light-colored and basal part buff. Lies 6 to 10 feet above Forbes limestone and 5 to 6 feet below Union limestone. Thickness 2 feet 7 inches to 4 feet. Outcrops west of Meadow, Nebraska, and at other places. Fossils (POLYPORA ELLIPTICA, fusulinids, ALLORISMA). Age is Pennsylvanian. Report includes measured sections, cross sections.
Type locality: in Keiwitz quarry west of Meadow Station, Sarpy Co., southeastern NE. Named from Meadow, north of Louisville, southeastern NE.

Summary:

Pg. 43, 51. Meadow limestone bed of Calhoun shale member of Shawnee formation. Named the shale overlying Meadow limestone the Iowa Point shale and the shale underlying it the Jones Point shale, and assigned all 3 to Calhoun shale member. He also renamed Union limestone (preoccupied) the Coal Creek limestone. Age is Late Pennsylvanian (Missouri age). Report includes cross sections, measured sections, geologic maps, stratigraphic tables.

Summary:

Pg. 11, 12, 26, 28, 31, 47. It has been found that Meadow limestone as originally defined should be extended to include a shale and a limestone next above; that (by tracing) the true Meadow limestone is basal bed of Stanton limestone member, instead of in Calhoun shale member; that the shale underlying the Meadow is not the Jones Point shale but Vilas shale member; that the true Jones Point shale is basal bed of Calhoun shale member and Iowa Point shale is top bed of Calhoun shale member. The limestone separating Jones Point shale and Iowa Point shale not the the limestone that outcrops west of Meadow it is here named Sheldon limestone and the shale overlying Meadow limestone is here named Eudora shale. The Meadow limestone as here redefined is 10.5 feet thick, and consists of (descending): limestone, 4 feet; shale, 3 feet; limestone, 3.5 feet. Age is Pennsylvanian.

Summary:

Pg. 33-34. Although unit was properly defined with relation to its position and sequence in the section its age and correlation has proved to be in error. Name has been in use for more than 30 years but is now dropped and name Merriam accepted by the Nebraska State Geol. Survey.
