ABSTRACT
Presence of fusiform fusulinids in Marble Falls limestone indicates this formation is post-Morrow in age. Lampasas is not appropriate as a series name, because in its type area it is only partly exposed and because as defined it includes beds of Des Moines age and excludes part of the Marble Falls, which is post-Morrow in age. Elevation of the Atoka formation of Oklahoma to Atoka series and use of this term in Central Texas is proposed.
