These rounded stones are labeled in our collections as gastroliths (literally "stomach stones") from Starr Springs near Hanksville, Wayne County, Utah. I'm featuring them this week in honor of our Utah Project team working right now in the baking Black Rock Desert near Fillmore, Utah.. From their reported location, these stones are likely out of the Summerville Formation (Middle-Upper ...These fusulinids comprise 31 species of 11 genera and could be, ascendingly, grouped into two assemblages: Yangchienia-Nankinella assemblage and Chusenella-Rugosofusulina assemblage. The age of ...Among the most characteristic fossils of the latter part of the Palaeozoic are the group of Foraminifera known as the fusulinoids. These forams, known from around the middle of the Carboniferous to the end of the Permian, can be extremely abundant. Indeed, I get the impression that some fossil deposits are pretty much made of fusulinoids.Fusulinids—Fusulinids (fig. 12) were small marine organisms that populated the seas worldwide during the Pennsylvanian Subperiod and Permian Period. The earliest fusulinids occur in rocks deposited during the late Mississippian Subperiod. Fusulinids became extinct during the mass extinction at the end of the Permian Period. These fusulinids biogeographically demonstrate the feature of peri-Gondwana province and signify a temperate-water condition. Further comparison suggests the Baoshan Block was located distant from the tropical region and even with higher latitude than Central Iran and Central Pamir during the Sakmarian–Yakhtashian. In contrast, …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).

Congeneric species are known to occur stratigraphically from near the base of the Morrowan series to near the top of the Pennsylvanian system. Fusulinids were the most diagnostic Late Paleozoic warm-water benthic foraminifers because they were widespread within tropical and subtropical settings (Kobayashi 1999; Ueno 2003) and they evolved rapidly and reached high taxonomic diversity during their short biostratigraphic ranges (Ross 1967; Ross and Ross 2003; Hada et al. 2015).The fusulinids first appeared late in the Early Carboniferous Epoch, which ended 318 million years ago, and persisted .
