Fusulinids

The fusulinids represented in these sa1nples include several genera characteristic of rocks of Middle Penn­ sylvanian age and include N ankinella, Staff ella, Pseudo-8t(tffella, F1.ls1.tlinella,, and F1.~J8uUna. The species are relatively primitive forms and as such do not suggest latest Middle Pennsylvanian age. As no fusulinids have.

Jan 1, 2021 · Although photosymbiotic fusulinids predominantly occur in tropical carbonate deposits with high production rates, their symbiosis also makes fusulinids highly sensitive to temperature, which has important biogeographic consequences during times of major climate fluctuations (Weidlich 2007). dance of fusulinids, and the fusu-linids seem to offer the best available clues as to the age of the limestone. The following systematic fusulinid study is based entirely on the col-lections mentioned. Foster (1923), who listed "Schwa-gerina sp." from the middle portion of the Yanghsin limestone, appar-ently was the first to report fusulinids

Ehrenberg (1839) Alveolinidae is a family of spheroidal to fusiform milioline foraminifera with multiple apertures and complex interiors in which chambers are subdivided into chamberlets and subfloors interconnected by passageways.
