“…The foraminiferal fauna determined from the carbonate pebbles and cobbles of the Lower Jurassic conglomerates allows us to date the source of the cobbles as Serpukhovian-Late Carboniferous. The taxonomic composition of fusulinids described from the studied carbonates is comparable to those described from coeval Carboniferous-Lower Permian strata of Svalbard, the Volga-Urals and the Pechora region (Rauser-Chernousov, 1958;Rozovskaya 1958;Grozdilova, 1966;Solov'eva, 1984;Davydov & Nilsson, 1999).…”

Here we present the first description and images of foraminiferal fauna from the carbonate cobbles and pebbles of Early Jurassic polymictic conglomerates from Graham Bell Island, in the easternmost part of the Franz Joseph Land archipelago. The composition of the conglomerates suggests a proximal provenance area. The identified foraminiferal genera and species suggest a Serpukhovian-Late Carboniferous age for the primary carbonates from which the conglomerate clasts were derived, and which can be correlated with coeval carbonate strata of Svalbard, the Volga-Urals and the Pechora region. Combined with previous studies, our new data lead us to assert that a shallow-marine carbonate platform occupied the entire Barents shelf, including its northeasternmost part, during Carboniferous-Early(?) Permian time. This study improves our understanding of the composition and age of pre-Mesozoic successions of Franz Joseph Land and surrounding parts of the Barents Sea.

“…ohioensis were known from the Missourian-Virgilian in North America (Dunbar & Condra, 1927;Newell, 1934;Thompson, 1936), belonging to the Midcontinent-Andean Province. Additionally, Rauserites rossicus and Triticites variabilis in the present fauna are also documented in the Arctic Province, for example, arctic Norway (Davydov & Nilsson, 1999) and North Greenland (Davydov et al, 2001). Broadly speaking, the fusulinid fauna in the Qi'eshan For- Basin and South China (X.…”

First record of Late Pennsylvanian fusulinids from the North Tianshan belt, NW China

et al. 2021

A noteworthy late Pennsylvanian fusulinid fauna is for the first time reported from the Qi'eshan Formation in the Eastern Tianshan, NW China. From three main outcrop sections, 19 species of six genera are identified and illustrated, among which several index taxa are described in detail. The present fusulinids are assigned to the middle Kasimovian to early Gzhelian in age, representing the youngest fusulinid fauna in northern Xinjiang up to now, which constrains the age of the Qi'eshan Formation up to the early Gzhelian. Palaeobiogeographically, the fusulinid fauna in the Eastern Tianshan was closely related to the populations from Central Asia (e.g., southern Fergana, the Alay Mountains and Darvaz) of the western Palaeotethyan Subprovince, and kept exchanging with those from the Eastern European Platform of Ural Province, given the common, particularly endemic species. The characteristic species include Montiparus ex gr. sinuosus alaicus, Rauserites rossicus, Schwageriniformis fusiformis, Triticites acutus, Triticites arcticus, and Triticites arcticus cybaeus. This palaeobiogeographic affinity suggests that the close of timing of the North Tianshan Ocean was later than the Early Gzhelian, and that the southern Urals and western Palaeotethys shared a common fusulinid fauna during this period.

“…Schwageriniformis [type species: Schwageriniformis schwagerini‐formis (Rauser‐Chernousova, 1938) = Triticites schwageriniformis (Rauser‐Chernousova, 1938)] was earlier identified as the primitive Triticites . However, with the further research, the Schwageriniformis considered as terminal stage in phylogenetic lineage Fusulinella ‐ Obsoletes , and appeared from middle Kasimovian to Gzhelian in central Asia and the Russian Moscow Basin (Davydov, 1990; Leven & Davydov, 2001). Triticites identified in this study commonly occurs in the strata of late Kasimovian to Gzhelian in the western Guizhou, South China (Zhang et al, 2010).…”

Controlling of the Late Palaeozoic glaciation on reef evolution: A case study of a late Kasimovian coral reef in southern Guizhou, South China

et al. 2023

A late Kasimovian (Pennsylvanian) coral reef is reported in the Yanbanzhai (YBZ) area, southern Guizhou Province, South China. The YBZ coral reef, with a thickness of approximately 5.5 m and a lateral exposure of nearly 50 m, is primarily composed of the colonial rugose coral Fomichevella. The fusulinids collected from the reef indicates a late Kasimovian age. Five microfacies types have been identified, including coated bioclastic grainstone, coral (Fomichevella) framestone, bioclastic wackestone, bioclastic grainstone, and peloidal grainstone. The vertical evolution of the microfacies in the YBZ coral reef indicates major sedimentary environmental changes associated with relative sea-level changes. The growth of the reef-builder Fomichevella was controlled by the transgression and regression. Deep water promoted the upward expansion of Fomichevella, while shallow water inhibited its growth. Published records of atmospheric pCO 2 estimation and sea-surface temperatures, combined with geochemical proxies, confirm a warm climatic period during the late Kasimovian. This is an interglacial period conducive to the growth of the coral reef. Sea-level and climate changes associated with the Late Palaeozoic ice age (LPIA) are interpreted as significant controls of the development of the YBZ coral reef. This research of the YBZ coral reef in South China provides practical palaeobiological evidence for global sea-level rising during the late Kasimovian period caused by the highlatitude Gondwana delaciation.
