Abstract
The transgressive part of the Finis Shale cycle (Graham Formation, Cisco Group, Virgilian, Pennsylvanian) in North-Central Texas contains abundant conodonts of the group Idiognathodussimulator, the species I. simulator being the global marker of the Kasimovian–Gzhelian boundary. The interval also has a dominantly agglutinated foraminiferal fauna with scarce calcareous taxa. A thin calcareous unit with a diverse Triticites fusulinid fauna directly underlies the Finis Shale.
