Provenance of Late Paleozoic-Mesozoic Sandstones, Taimyr Peninsula, the Arctic

Geosciences, 2013
The sedimentary and provenance characteristics of seven Permo-Carboniferous and two early Cretaceous samples from the Taimyr Peninsula provide information about the latest evolution of Uralian orogeny and the opening of the Amerasian Basin.

Evolution of prototype basin and change of tectonic-sedimentary pattern in Paleozoic, Ordos Basin

Shiyou shiyan dizhi, 2022
The Ordos Basin is a craton basin developed based on the Precambrian rift system during Permian. It has experienced two stages of evolution including the Early Paleozoic craton marginal depression and Late Paleozoic intra-craton depression.

Evolution of leaf-form in land plants linked to atmospheric CO2 decline in the Late Palaeozoic era [PDF]

, 2001
The widespread appearance of megaphyll leaves, with their branched veins and planate form, did not occur until the close of the Devonian period at about 360 Myr ago.

Late Carboniferous – Early Permian (Ghzelian – Artinskian) Palynomorphs

Journal of Micropalaeontology, 1985
Abstract. The preliminary results of the palynological investigations in the Late Carboniferous – Early Permian of Northeast Libya indicate that at least two successive intervals can be readily recognised:Ghzelian – Asselian interval. This lower interval is characterised by assemblages showing a dominance of saccate pollen; miospores usually occur in ...

New annulate Carboniferous orthoconic and cyrtoconic cephalopods of the family Brachycycloceratidae Furnish, Glenister & Hartman, 1962

European Journal of Taxonomy
The Carboniferous orthoconic or slightly cyrtoconic cephalopod family Brachycycloceratidae Furnish, Glenister & Hansman, 1962 is well described based on material from North America, whereas the Early Carboniferous European occurrences of this family are
