Fusulina, an excellent index fossil for Late Carboniferous rocks, enables widely separated rocks to be.USGS Publications WarehouseFusulinids are larger benthic foraminifera of late Paleozoic and index fossils for Permo-Carboniferous strata. The traditional methods to examine their internal structures are through ground thin sections, which however caused lots of ambiguities regarding the morphological diagnostics and taxonomic identification.

The fusulinids first appeared late in the Early Carboniferous Epoch, which ended 318 million years ago, and persisted.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 elongated rice-shaped forms. ….

Transcribed image text: Paleozoic Marine No. 13 Phylum Protozoa These little things that look like grains of rice are actually huge foraminifera (forams) called fusilinids. They are common in Pennsylvanian and Permian rocks. Fusulinids within these limestones are valuable for age dating and paleogeographic analysis, due to their rapid morphological evolution and ecological sensitivity (e.g., Ross, 1995, Groves et al., 2012, Zhang and Wang, 2018, Arefifard and Clapham, 2021, Ueno, 2022).However, detailed taxonomic studies on fusulinids in the Changning-Menglian Belt remain limited, despite some reports dating back ...
