A total of 18,811 specimens were obtained, corresponding to 5 suborders--Textulariina, Spirillinina, Miliolina, Lagenina and Robertinina-, 13 families, 26 genera and 66 species (Figs.
However, representatives of the suborder Miliolina, almost absent in the section of Zambujal de Alcaria, attaint important relative abundances in some assemblages.
2%), followed by representatives of suborders Miliolina (5.
3%) and very scarce representatives of suborders Miliolina (1.
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.
Representatives of the suborder Miliolina are relatively important components in the assemblages from Maria Pares (5.
Concerning the representatives of the suborder Miliolina, they have been related with warm waters (Copestake and Johnson, 1981; Haynes, 1981; Murray, 1989), attaining up to 40% in assemblages from subtropical temperatures (Alegret, 2004).
To explain the high relative abundance of the representatives of the suborder Miliolina in the Maria Pares section, located in the middle part of the shelf, warmer water conditions must be invoked, as previously argued by Henriques and Canales (2013) in the near locality of Sao Giao, where representatives of the suborder Miliolina attaint relative abundances up to 76%.
