Pressure solution formed pits on 47 percent of the specimens, and another 3 percent have other fusulinids or fossil fragments embedded into them. Flattened or cracked specimens were not abundant,

Abstract. Agglutinated Foraminifera remained the dominant group in the Lower Palaeozoic but a spectacular increase in number and kinds of Foraminifera occurred in the Upper Palaeozoic with the rise of the calcareous microgranular group. With the advent of wholly secreted tests, Foraminifera became important contributors to limestones ... Fusulinella, genus of extinct fusulinid foraminiferans (protozoans with a shell) found as fossils in Late Carboniferous marine rocks (those formed between 320 and 286 million years ago). Because of its narrow time range and wide geographic distribution, Fusulinella is an excellent guide fossil for. ….
