FIGURE 7—Scale of taphonomic features observed in fossil Nummulites, as an indication of the degree of transportation or wave reworking, and to enable comparison between different facies and carbonate-platform environments in thin-section studies of nummulitic limestones. Test-damage features defined in categories 0, 1, and 2 are based on the experimental transportation of modern Palaeonummulites venosus (see Fig. 2); those in category 3 are based on field studies of Nummulites-bearing turbidites, and also are inferred from published taphonomic studies of larger benthic foraminifera. Determining which processes were responsible for the damage seen in category 3 may be aided by the identification of turbidites in the field, or by the recognition of unambiguous bioerosion features, such as the smooth, tubular borings attributed to sponges, annelid worms, and some bivalves

FIGURE 1—Scanning electron microscope images of tumbled Palaeonummulites venosus. (A) Control test of P. venosus, showing minor damage (missing terminal chamber); test surface has a polished, glassy appearance; sigmoidal septal filaments visible. (B) Damage to approximately 25% of the test periphery (note septa exposed due to removal of overlying test wall) and punctured test surface (sample 1). (C) Exposed septa are scratched and abraded (sample 1). (D) Damage to up to 50% of the test periphery (typical of samples 2–8). (E) Marginal cord of the penultimate whorl exposed by removal of overlying chamber (typical of samples 2–8). (F) Septa worn to reveal the septal canal (typical of samples 6–8). (G) Damage to 50–70% of the test periphery (typical of samples 9–14). (H) Septa, both partially worn, exposing septal canals, and completely worn to the level of the test surface (typical of samples 9–14). (I) Gouges on the test surface, which have locally smeared the pores (typical of samples 9–14). (J) Micro-pits in the test wall (typical of samples 13 and 14)
