In the section of Zambujal de Alcaria, the percentages of the suborders Textulariina and Spirillinina are relatively important, when compared to those of the remaining identified suborders, being the first one more abundant than the second one.
Recorded foraminiferal assemblages present a high relative abundance of the representatives of the suborder Lagenina (90.2%), followed by representatives of suborders Miliolina (5.6%) and Textulariina (3.5%), the representatives of suborders Spirillinina (0.6%) and Robertinina (0.1%) being only minor components.
The assemblages are dominated by representatives of the suborder Lagenina (90%), followed by Textulariina (6.1%), Spirillinina (2.3%) and very scarce representatives of suborders Miliolina (1.3%) and Robertinina (0.3%).
They are constituted by typical taxa of the Boreal Realm, on which representatives of the suborder Lagenina are the most abundant components (Haynes, 1981; Murray, 1989), usually accompanied by variable percentages of representatives of the suborders Textulariina, Spirillinina, Miliolina, Robertinina and Rotaliina depending on paleoecological conditions.
Las asociaciones de cienagas y manglares se caracterizan por contener un 100% de textulariina (aglutinados) en cienagas alejadas a la costa, en comparacion con las formas rotaliina (hialinos) que caracterizan cienagas cercanas a la costa.
Debido al alto porcentaje de lageninos, se grafico junto con rotaliina y textulariina, (Fig.
Marsonella, Spriroplectammina and Coryphostoma characterize the textulariina forms.
Among the vagile benthic forms, the two main groups correspond to the Order Spirillinina (39%, mainly Spirillina and less commonly Conicospirillina) and the Order Textulariina (38%, mainly Reophax and Ammobaculites, with less abundant Ammodiscus, Redmondoides, Ammomarginulina, and Haplophragmoides).
Los foraminiferos bentonicos presentes, mayoritariamente corresponden al Suborden Rotaliina, Superfamilia Nonionacea (91,3% del total de organismos bentonicos), asi como en mucho menor numero al Suborden Textulariina, Superfamilia Lituolacea, ?Reophax sp.
Los foraminiferos bentonicos presentes en la muestra analizada del afloramiento corresponden al Subordenes Rotaliina y Textulariina. Lo anterior permite realizar una asociacion paleoambiental con lagunas litorales de agua salina, ligeramente salobres o estuarios (Brasier, 1980); lo que concuerda con el paleoambiente definido a traves del estudio de la malacofauna e icnofosiles del afloramiento.
Sometimes, calcareous benthic foraminiferal abundances increase with progradation of highstand systems tract carbonates and abundances of Textulariina increase with prograding lowstand systems tract.
