Upper Permian (Guadalupian) Facies and Their Association with Hydrocarbons—Permian Basin, West Texas and New Mexico

AAPG Bulletin, 1986
ABSTRACT Outcrops of Guadalupian sedimentary rocks in the Permian basin of west Texas and southeastern New Mexico are a classic example of the facies relationships that span a carbonate shelf. In the subsurface, these rocks form classic hydrocarbon-facies traps.

Plesiosaur ancestors from the upper permian of Madagascar

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981
Abstract Numerus well preserved fossils from the Upper Permian of Madagascar are structurally intermediate between primitive diapsid reptiles and nothosaurs and plesiosaurs. Claudiosaurus germaini (gen.nov., sp.nov.) is similar in its basic anatomy to eosuchian reptiles such as Thadeosaurus colcanapi (gen.nov., sp.nov.), but the ...

Brachiopod assemblages from the Upper Permian and Permian–Triassic boundary beds, South China

Canadian Journal of Earth Sciences, 1980
Uppermost Permian (Changhsingian) brachiopods are abundant and diverse in South China; thus far, 60 genera and 130 species have been described from the Changhsing Formation. Two distinctive brachiopod faunas can readily be identified from a single Changhsingian zone, the Peltichia zigzag–Paryphella sulcatifera Assemblage Zone.

THE INTERREGIONAL CORRELATION OF THE TATARIAN AND THE PROBLEM OF THE PERMIAN UPPER BOUNDARY

International Geology Review, 1992
As the Permian was initially established on the Russian Platform, the sequence of Permian stages with type sections on the platform is traditionally considered as the standard and has served to define the Permian. Consequently, the upper boundary of the Tatarian on the Russian Platform should, by definition, be considered as the upper boundary of the ...

Sandstones and Channels in Upper Pennsylvanian and Lower Permian in Kansas

AAPG Bulletin, 1956
ABSTRACT During recent field work in Kansas, many channel sandstones were discovered in the upper Pennsylvanian and lower Permian rocks. The new channels originated in the Willard, Pierson Point, Langdon, Pony Creek, West Branch, and Hamlin shales and the Caneyville limestone. Some of them are as much as 110 feet deep.

Upper Permian (Tatarian) Brachiopods from New Zealand

New Zealand Journal of Geology and Geophysics, 1967
Abstract Fifteen species of Brachiopoda are described from limestones of the Stephens Formation (lower Tatarian) and from the Wairaki Breccia (upper Tatarian) of New Zealand. The Stephens fauna represents the youngest known cold‐water fauna of the Permian Gondwana realm.
