TL;DR: In this article, a new flora from the Upper Permian Hongshan Formation of Acheng County, Heilongjiang Province, Northwest China is described, which is dominated by Angara species but mixed with some typical Cathaysian elements.
Abstract: This work documents a new flora from the Upper Permian Hongshan Formation of Acheng County, Heilongjiang Province, Northwest China. The flora consists of 20 species: Paracalamites sp., Pecopteris tangwangheensis Huang, Callipteris obese Huang, Callipteris shenshuensis Huang, C. tangwangheensis Huang, C. heilongjiangensis Huang, C. zeilleri Zalessky, C. sp., Comia yichunensis Huang, C. tenueaxis Huang, Iniopteris sibirica Zalessky, Supaia teiliensis Huang, Compsopteris tchirkovae Zalessky, C. cf. adzvensis Zalessky, Nilssonia sp. 1, Nil. sp. 2, Taeniopteris cf. densissima Halle, T. cf. nystraemii Halle, T. sp. and Noeggerathiopsis derzavinii Neub. It is dominated by Angara species but mixed with some typical Cathaysian elements. The age of the flora is assigned to late of the Late Permian according to the stratigraphic ranges of the known species and the comparisons of it with the similar floras. The new discovery indicates that the final collision between the North China Plate and Siberian Plate occurred in Late Permian along the Xar Moron River-Changchun-Yanji sutured zone, and the Paleoasian Ocean was finally closed at the end of the Permian.

TL;DR: Two compression floras have been discovered below the Brush Creek marine unit (lower Conemaugh) in Columbiana County, Ohio as mentioned in this paper, including Sphenophyllum oblongifolium, Pecopteris candolleana, Danaeites emersonii and Odontopteris brardii.
Abstract: Two compression floras have been discovered below the Brush Creek marine unit (lower Conemaugh) in Columbiana County, Ohio. One flora is preserved in freshwater ironstone beds 6 m below the Brush Creek and contains abundant pteridosperm and sphenopsid elements. The assemblage includes Sphenophyllum oblongifolium, Pecopteris candolleana, Danaeites emersonii and Odontopteris brardii, taxa previously recorded from younger strata. The second assemblage occurs within a 1.5-m-thick argillaceous, freshwater shale directly below the Brush Creek and yields abundant lycopod, cordaite, and conifer remains. The latter elements, some of which are permineralized with pyrite, represent the earliest occurrence of conifers in the eastern United States known to date. OHIO J. SCI. 88 (1): 48-52, 1988

TL;DR: Recently, Zhang et al. as mentioned in this paper discovered numerous representatives of the genus Annalepis in the same Lowermost Triassic beds: A. latiloba, A.brevicystis and A.angusta, which are associated with a basal Triassic marine fauna.

TL;DR: Although subtle, the four pecopterid species are differentiable from one another by combined FTIR characteristics, supporting taxonomy, and the ratio of CH 2 /CH 3 is hypothesized to be a chemotaxonomic parameter for Pennsylvanian pteridophylls.
