Fusulinids

The abundant fusulinids of the Hughes Creek Shale Member of the Foraker Limestone in east-central Kansas are noted for their excellent preservation (Hageman and Kaesler, 1998). Not all these fossils are in pristine condition, however, as taphonomy has taken its toll. We deal in part with necrolysis during predation, but we examine more ....

A wealth of data on Permian fusulinids of the Baoshan Block has been accumulated in past years (Fang et al., 2000, Ueno, 2003, Huang et al., 2009, Shi et al., 2011, Huang et al., 2015a) and was recently reviewed by Huang et al. (2015b).In that review, Guadalupian fusulinids newly collected from the Bawei Section in the southern Baoshan Block were briefly reported.Found this piece near a bunch of Carboniferous fossils in limestone, any ideas?

These Texas fusulinids don't show any evidence of P-sol, but rather serve as exemplars of undeformed strain markers. They are HUGE! Remember that each of these is a single-celled organism - one nucleus per critter. Unlike a lot of forams, these fusulinids are interpreted to have been benthic (bottom-dwellers), not planktonic (floaters).The fusulinids as a large, warm-water foraminifera were quite sensitive to water temperature.

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

The rarity of large fusulinids in the Fars and Zagros Mountains seems to be related to shallower and/or more confined environments (Gaillot and Vachard 2007). During the Wordian-Capitanian interval, weak fluctuations of floro-faunal associations are directly correlated with changes in depositional environments. At the Guadalupian/Lopingian ...The study of fusulinids is important because large amounts of oil and gas have been found in rocks as- signed to the Pennsylvanian and Permian Systems in which ... ….

This article presents the first large image dataset of fusulinids containing 2,400 images of individual samples subjected to 16 genera of all six fusulinid families and labelled to species level.

Large fusulinids reached lengths of >10 cm and diameters of up to 1 cm. These larger fusulinids differ from smaller fusulinids primarily through a wall structure containing a tectum and keriotheca, which are interpreted as adaptive structures for hosting algal symbionts (Ross, 1972, Ross, 1982, Ross, 1992; Vachard, 1996). A keriothecal wall is ...Fusulinids are the most diverse, abundant and geographically widespread Paleozoic foraminifera which are widely considered to possess a “homogeneously microgranular” test microstructure ...fusulinids (e.g., Thompson, 1954) and other fossil assemblages from the Admire Group and overlying lower part of the Council Grove Group, and correlative units throughout North America, were dated as earliest Permian (early Wolfcampian).
