Abstract

Rugose corals, only locally common in the Pennsylvanian Gaptank Formation, include Dibunophyllum moorei, Dibunophyllum sp. A, Neokoninckophyllum dunbari, n. sp., from Des Moinesian strata, and N. cooperi, n. sp., Pseudozaphrentoides ordinatus, n. sp., Lophopyllidium vallum, n. sp., L. solidum, n. sp., Leonadophyllum kingi, n. sp., Amplexizaphrentis sp, and Amplexocarinia sp., from Virgilian strata. The Permian (Wolfcampian) Neal Ranch Formation contains Neokoninckophyllum deciensis, n. sp., and Lophophyllidium cf. L. vidriensis, n. sp., and the Permian (Wolfcampian) Lenox Hills Formation has Amplexocarinia sp. A, Dibunophyllum hessensis, n. sp., Dibunophyllum sp. B, Lophophyllidium vidriensis, n. sp., L. skinneri, n. sp., Stereostylus tergidus, n. sp., and Amplexocarinia sp. The Gaptank Formation is equivalent to the upper part of the Des Moinesian Series, the upper part of the Missourian Series and the Virgilian Series of the U.S., and the Moscovian, Zhigulevian, and Orenburgian series of Russia, The lower part of the Wolfcampian Series, the Neal Ranch Formation, is equivalent to the Council Grove Group of Kansas and the Asselian Series of Russia; and the upper part of the Wolfcampian Series, the Lenox Hills Formation, is equivalent to the Chase Group of Kansas and the Sakmarian (restricted) of Russia.
