Fusulinid
Microgranular-walled fusulinid foraminifera was abundant in the shallow marine environment and built fusulinid limestone across the tropical belt stretching from the North American platform to Europe and Southeast Asia in the east. The fusulinids became extinct at the end of the Permian mass extinction. The LBF again appeared in the Cretaceous ...This review has been undertaken in order to present some interpretations about the bio-stratigraphy of the smaller foraminifers belonging to four classes present during the Permian: Fusu-linata, Miliolata, Nodosariata and Textulariata. The microfacies types of the limestones in ascending order are: (1) bioclastic grainstone/packstone, (2) fusulinid grainstone/packstone, (3) smaller foraminiferal grainstone/packstone, (4) Anthracoporella (dasycladale) grainstone/packstone, and (5) wackestones. Twenty-three species assignable to 15 genera of fusulinids were recovered from the ...

View all · Foraminifera: Zellia and Parafusulina (PRI) 3D Model.Fusulinid biozones are acme or assemblage zones in which an abundant occurrence of the index and associated species is related to relative sea-level change and therefore the bases and tops of proposed zones are bound with unconformities, erosional surfaces or soil formations. Three fusulinid cycles are recognized in the "M" Formation of the ...The present study provides a synthesis of the known global distribution and migratory timescales of Biwaella and describes the first occurrence of B. americana Skinner et Wilde, 1965 from Nevada, USA.

Fusulinid taphonomy studied here is both biostratinomic and diagenetic. Biostratinomic processes are expressed in two forms: encrustation and corrasion. The diagenetic processes comprise compaction and dissolution. During diagenesis, additional corrasion may take place along with compression and dissolution, both of which distort …The Finis Shale is part of a cyclothem and represents the shallowing upwards sequence at this outcrop.

These images are segmented from literatures and thin-slice micrographs utilizing a deep-learning model called BlendMask. Images are labeled to species level and with scale information. This dataset can foster studies in ...This fusulinid genera has been acknowledged to be an index for the eastern Tethys and Panthalassa (e.g. Kobayashi, 1999; Kasuya et al., 2012), thus bears particular paleobiogeographic significance.

To make fusulinid morphospecies more accordant with biological species, it is necessary and reasonable to constrain the conventional determination of fusulinid species with population-level ...This study is based upon the Tethyan Province fusulinid biostratigraphy that was established by numerous studies carried out in 1950–1970s (e.g. Kanmera, 1954, Sheng, 1963, Ozawa, 1975, Toriyama et al., 1975). In particular, we provide new data on unique fusulinid faunas found from the upper part of the Khao Tham Yai Limestone.The Early Permian fusulinid fauna correlates very well with the fauna of other sections in the Palaeotethyan realm (Southern Alps, Central Asia, Southern China and Japan). View Show abstractkraffti, which is unusual among the known late Early Permian fusulinid faunas from the eastern Cimmerian continent. In contrast, a number of late Artinskian-early Kungurian fusulinid faunas were known in the eastern Cimmerian blocks, but they have less faunal linkage to the paleo-tropical Tethyan region (Ueno et al., 2015).Kireeva, G.D. 1964: On the taxonomie analysis of the wall structure of certain fusulinid genera from the border between the Middle and Late Carboniferous Voprosy Mikropaleontologii 8: 53-56.

The fusulinid fauna from the Xishancun section in the Shanmutang area is dominated by Chusenella and Nankinella, whereas that from the Shuangheyan area is composed mainly of Chusenella and Schwagerina. Both faunas are dated as Roadian–Capitanian (middle Permian). A relatively complete succession of the Bashkirian to Moscovian rocks is exposed in the Hadim Nappe, central Taurides, where rich and diverse fusulinid assemblages have been analysed in three sections (Yassıpınar, Gölbelen and Bademli). The Bashkirian-Moscovian successions mainly consist of medium-bedded sandstones, medium-thick-bedded oolitic limestone and thin-medium bedded ...The fusulinid biozonation between this belt and South China is analogous throughout the Carboniferous–Permian periods (Zhou, 1995, Fang et al., 1999a, Ueno et al., 2003, Ueno and Tsutsumi, 2009). The present study demonstrates comparable Late Carboniferous to Early Permian faunal successions between these two regions. Ozawa (1929) dated fusulinid foraminifers from Telok Gedang as Carboniferous, but Thompson (1936) examined Tobler's collections and proposed an early Permian age.
