The Permian of Pakistan has been well known, yet poorly understood. Pakistan represents one of the few places where the Permian of the Paleotethys (Northern Hemisphere) and the Permian of Gondwana both occur. This chapter will review the stratigraphy of Pakistan that represents the northern part of the Indian/Pakistan plate.

Revision of the stratigraphy of Permian and supposed Permian rocks of Southern Scotland
Geologische Rundschau, 1978The formal stratigraphy of the Permian basins of southern Scotland is described for the first time. These rocks consist of piedmont breccias and lavas, overlain by wadi-fan and dune complexes, and alluvial fan and floodplain sediments. The sequences are inferred to be Stephanian to Lower Permian in age and correlatable with similar continental ...

Permian-Triassic Extinctions and Rediversifications
2015Ammonoids were a major component of Permian marine faunas, but were on the verge of extinction during the Permian-Triassic crisis ~ 252 myr ago. Despite the severity of this extinction, their recovery was explosive in less than 1.5 myr. By Smithian time, they had already reached levels of taxonomic richness much higher than those of the Permian.

The Random Samples item “Permian pollen eaters” ([16 May, p. 1035][1]) provides a stimulating account of the discovery by Russian paleobiologists Alexander Rasnitsyn and Valentin Krassilov of identifiable pollen in the guts of Early Permian insects. Paleobotanist William Chaloner is quoted as saying that inadvertent consumption of pollen could explain ...

Upper Permian Sediments in Southeastern Permian Basin, Texas
1968Throughout most of late Permian time the southeastern Permian Basin was part of a shallow barred lagoon located in an area of high evaporation and low rainfall. Refluxion to the open sea farther west was slowed by the intervening Capitan barrier reef during Guadalupian time, but free surface influxion of sea water occurred.
