“…Thus, the use of foraminifera as bioindicators is more suitable to better understand environmental disturbance. This approach was initiated in the early 1960s by Resig (1960) and Watkins (1961). Later, similar studies have been carried out in different environmental settings.…”

A study of chemical and sedimentological parameters integrated with benthic foraminifera investigation was conducted along the northern coast of Gabes Gulf. Thirty-two samples were studied and a total of 68 benthic foraminiferal species were identified. Heavy metals enrichment factors and total hydrocarbon concentrations showed both metal and petrogenic pollution related mainly to phosphogypsum, sewage, and fishing activities. Statistical analysis (bivariate correlation and hierarchical cluster analysis) show a possible control of these pollutants on density, diversity, as well as the taxonomic composition of the benthic foraminiferal assemblages. The extent to which the population was found less dense and less diversified corresponded to the degree to which the sediment was contaminated. In these contaminated sites, an increase in relative abundance of opportunistic species such Ammonia tepida and Haynesina germanica was found. Far from pollution, foraminiferal assemblages are dominated by species characteristic of Mediterranean shallow water (Ammonia beccarii, Ammonia parkinsoniana, Elphidium crispum, Elphidium williamsoni, Elphidium advenum, Peneroplis planatus, Peneroplis pertesus).

“…Changes in density and assemblage composition are not the only response by benthic foraminifera to organic matter, with a reduction of species diversification also being reported in the vicinity of many outfalls (e.g. Resig, 1960). The development of an azoic area, high concentrations of sulphides, and reducing conditions are documented around the point sources (mainly pulp and paper mills) of refractory organic matter.…”

“…Recent studies have extensively documented foraminiferal test deformities from areas contaminated by heavy metals or other chemicals due to domestic sewage, and/or hydrocarbon spills (Resig, 1960;Alve, 1991;Yanko et al, 1998;Geslin et al, 1998;Samir, 2000;Geslin et al, 2002, Vilela et al, 2004Buzas-Stephens and Buzas, 2005;Meriç et al, 2005;Cevison and Hallock, 2007;Luciani, 2007;Fontalini and Coccioni, 2008;Polodova and Schönfeld, 2008;Madkour and Ali, 2008;Debenay et al, 2009;Martínez-Colón et al, 2009). However, it is important to emphasize that anthropogenic pollution is not always the cause of abnormal test formation (Stouf et al, 1999a).…”

During the early Maastrichtian an assemblage rich in large foraminifera, mostly composed of orbitoidal foraminifera, developed in the shallow-water deposits of the Cárdenas Formation (Valles-San Luis Potosí Platform, Mexico). Among them, the most abundant is Lepidorbitoides minima, some of which display a morphologically abnormal test consisting of polyvalent forms, conical tests and budding, which could be induced by abrupt changes in environmental factors. The occurrence of the abnormalities preceded the demise of this species and of all the larger foraminiferal association in the upper part of the Gansserina gansseri Zone (early Maastrichtian). The abnormalities could be induced by environmental stress, probably related to interplay of different events such as increased terrigenous input and the transition to deeper facies due to Laramide tectonic instability before the K/P boundary.A late Maastrichtian community of dwarfed planktic foraminifera composed of Trinitella scotti Brönnimann, Plummerita reicheli Brönnimann, Rugoglobigerina cf. macrocephala Brönnimann, Rugoglobigerina hexacamerata Brönnimann, Heterohelix punctulata (Cushman), Pseudoguembelina costulata (Cushman), Pseudotextularia intermedia de Klasz, Globigerinelloides asperus Bolli, Guembelitria cretacea Cushman, Rugoglobigerina rugosa (Plummer), Rugotruncana sp., Globotruncanita stuarti (de Lapparent), and Globotruncana arca (Cushman) developed in the upper part of the sequence. This uncommon morphology could also be related to the highly stressed paleoenvironmental conditions related to global climatic change and local tectonic activity. Associated with this planktic assemblage is a deeper-water dwarfed benthic foraminiferal community composed of Gyroidinoides nitidus (Reuss), Coryphostoma incrassata (Reuss), Pseudouvigerina plummerae Cushman, P. cretacea Cushman, Bolivina cretosa Cushman, Planulina texana Cushman and Cibicides harperi (Sandidge).Keywords: Abnormal foraminifera tests, Lepidorbitoides minima, dwarfed planktic foraminfera, Maastrichtian, Cárdenas Formation, Valles-San Luis Potosí Platform.
