Fossiliferous limestone from Tunisia. PPL image, 1x (Field of view = 9mm) Partially dolomitized Fusulinid fossils (the rhombohedral crystals are dolimite).Foraminifera (forams for short) are single-celled organisms (protists) with shells or tests (a technical term for internal shells). They are abundant as fossils for the last 540 million years. The shells are commonly divided into chambers that are added during growth, though the simplest forms are open tubes or hollow spheres.The great abundance of fusulinid tests in many of the sandstone beds of the formation has been noted in descriptions of the stratigraphy (p. 29, see also fig. 11, A), and was first observed by Shumard. 87 The fusulinids all belong to the genus Parafusulina, which occurs also in the Bone Spring limestone below and the Cherry Canyon formation ...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).

Two additional fusulinid zones are reported from the southern Hills. In addition, two conodont faunas are described and illustrated. These fossiliferous horizons, together with previously reported fossils, indicate that the Pennsylvanian portion of Minnelusa is much thinner than has previously been reported.Experimental results on the fusulinid fossil dataset over five deep learning based milestone models show that OGS using three base models consistently outperforms the baseline using a single base model, …Temsip Fusulinid Fossil Site .

fusulina: [noun] a genus (the type of the family Fusulinidae) of large fossil spindle-shaped foraminiferans having a test with 4-layered walls and deeply folded septa and serving as an index fossil in various Lower and Middle Pennsylvanian rocks.The fossil content of this limestone is commonly dominated by small foraminifers, fusulinids, corals, bryozoans, crinoid stems and brachiopods. It is also ...
The fusulinids are among the earliest calcareous-walled foraminifera; they appear in the fossil record during the Llandoverian epoch of the early Silurian. The earliest of these were microscopic, planispirally coiled, and evolute; later forms evolved a diversity of shapes including lenticular, globular, and perhaps most famously, elongated rice ...The most common microbial fossils are fossil algae.
