Biostratigraphie des kystes de dinoflagellés et paléoenvironnements dans l’Eocène de la coupe d’Ibn Batouta, région de Tanger, Rif Externe occidental, Maroc

Paleoenvironmental and paleogeographic characterization of the 12 frères borehole, fresco, southwestern Côte d’Ivoire: Palynological implication

“…and Achomosphaera spp. It characterizes an outer neritic environment[10,11,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].  The Senegalinium Group includes cornucavate peridinioid cysts, such as Cerodinium spp, Palaeocystodinium spp, Spinidinium spp, Senegalinium spp, Isabelidinium spp, and Deflandrea spp, which are heterotrophic cysts marking a neritic to oceanic depositional environment.…”

“…characterizes areas of high productivity[10,11,17,22,25,26,[34][35][36][37][38][39]  Impagidinium spp. is rather composed of proximochorate gonyaulacoid cysts which are typical of oceanic marine environments[10,11,17,18,22,30,31,35,[40][41][42][43]]  Palaeohystrichophora spp. consists of the peridinian cysts Palaeohystrichophora infusorioides and Palaeohystrichophora palaeoinfusa.…”

Qualitative and Quantitative Study of Dinoflagellate Cysts in Surface Sediments of the Nador Lagoon (North-East Morocco)

“…These species are responsible for intoxications that can sometimes lead to death and cause serious socio-economic consequences. In Morocco, many studies wereconducted on these dinoflagellate cysts (Hssaida, 1990; Hssaïda & Morzadec-Kerfourn, 1993; Hssaida et al, 2014; Chekar et al, 2016;Daghor et al, 2016). Thus, the present work was organized to carry out a quantitative and qualitative study of dinoflagellates in the water and surface sediment of the Nador lagoon.…”
