El Phylum Bacillariophyta fue el mas representativo con 15 973 Ind.[1.sup.-1] (81.38%) seguido de Chlorophyta con 2 317 Ind.[1.sup.-1] (11.80%) y Cyanobacteria con 1 098 Ind.[1.sup.-1] (5.59%), entre los grupos con menor densidad se encuentran Charophyta con 132 Ind.[1.sup.-1] (0.67%), Euglenophyta y Miozoa con 2 Ind.[1.sup.-1] (0.01%) cada uno.
Based on our findings, the lack of proteins similar to the SC proteins of the model organisms in Rhodophyta, Euglenophyta, Chrysophyta, Charophyta, Xanthophyta, and Dinoflagellata makes it possible to assume that meiosis in these algae differs from classical meiosis in proceeding without any SC or that unknown new proteins form SCs in these algae.
According to Dias-Brito et al., (2001) the Adamantina formation's fossil sediments are primarily represented by vertebrates (remains of crocodylomorphs, dinosaurs, turtles, frogs, fish, snakes), plants (Charophyta) and molluscs (conchostraceans and ostracods).

There is convincing evidence that, among Chlorophyta (s.l.), members of the Charophyceae (e.g., Coleochaete, Nitella, Chara) possibly offer critically important clues to landplant origin (Prescott, 1968; Graham, 1984, 1993); some authors (e.g., Bold et al., 1987) recognize the Charophyceae as "Charophyta," a division distinct from Chlorophyta, perhaps more closely related to embryophyte plants (than other green algae).
Algae are classified into different division (phylum) namely Chlorophyta, Charophyta, Phaeophyta, Rhodophyta, Bacillariophyta, Xanthophyta, and Euglenophyta.
Accumulations of charophyte calcified oospheres, the gyrogonites, were previously usually interpreted as indicators of lowered salinity, however, many charophyte species from the Devonian sections have been found to be associated with typical marine assemblages, showing that the first representatives of the Charophyta were adapted to a wider variety of sedimentary environments than their modern relatives (Georgescu & Braun 2006).
