Summary:

Bell's Landing marl (new name for exposures at Bells Landing, on Alabama River, in Monroe Co.) consists of greensand shell marl with indurated bed in its midst or at top. Thickness 10 to 15 feet. Separated from younger Wood's Bluff marl by 50 to 80 feet of lignitic clays and sands. Included in LaGrange or Lignitic. Age is early Eocene.

Summary:

Unit is fossiliferous marine marl, 10 feet thick. Distinguished from all other marls in AL by great size of shells it contains. Overlain by 40 feet of sandy strata, forming top of Bell's Landing section, and separated from the older Gregg's Landing marl by 20 to 25 feet of dark-gray sandy clays.

Summary:

Occurs in the lower part of the Tuscahoma Sand of the Wilcox Group, but above the Greggs Landing Marl Member. Unit is 9 ft thick and is a very fine grained glauconitic, fossiliferous sand, containing large pillow-shaped concretions. Age is Paleocene (Sabinian--late Thanetian), not Eocene as assumed by previous authors.

Summary:

The Bells Landing Marl Member of the Tuscahoma Formation is included in the upper part of calcareous nannofossil zone NP9 and is of late Paleocene age. The Bells Landing Marl Member is the uppermost shelly, glauconitic sand bed or marl of the Tuscahoma Formation.
