Permian

Danmarks Geologiske Undersøgelse Serie B, 1982
In North-West Europe two mega-basins began their development during Late Carboniferous to Early Permian: The South Permian Basin stretching from eastern England into Poland , and the North Permian Basin reaching from Scotland into Denmark. These two basins were separated by the Mid North Sea High and the Ringkøbing-Fyn High which came into existence ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Microfacies, depositional environment, sequence stratigraphy and diagenetic process affected the Doroud Formation in the Eram Section (south Neka), north flank of central Alborz [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Permian deposits (Doroud Formation) are exposed in a wide area of central Alborz. A stratigraphic section of Permian deposits in the Eram section (South Neka) has been selected for the study of facies, depositional environments, sequence stratigraphy,

Coccidioidomycosis in pregnancy: Case report and literature review of associated placental lesions

Case Reports in Women's Health, 2016
Background: Coccidioidomycosis is an endemic fungal infection found most commonly in the Southwestern United States, Northwestern Mexico, and parts of Central and South America. Although infection is relatively uncommon during pregnancy, it is imperative

On the Permian Chitonidæ [PDF]

Quarterly Journal of the Geological Society of London
The discovery of Chiton Loftusianus at Tunstall Hill, in 1844, by Messrs. Loftus and King, introduced the family Chitonidæ into the List of the Permian Fauna*. For several years this species remained its sole representative; but in 1856 another species was found in the same locality, and in ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Permian productidina of Britain and Malaysia [PDF]

, 1990
The British Permian Productidina have not been revised in detail since 1858. In the present study some 2000 specimens from 29 localities in north east of England have been collected and prepared in the laboratory and used together with museum collections.

Earliest Triassic microbialites in the South China Block and other areas; controls on their growth and distribution [PDF]

, 2007
Earliest Triassic microbialites (ETMs) and inorganic carbonate crystal fans formed after the end-Permian mass extinction (ca. 251.4 Ma) within the basal Triassic Hindeodus parvus conodont zone.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
