Algae, Acritarchs and Other Microfossils Incertae Sedis from the Lower Carboniferous of Saudi Arabia

Depositional cyclicity and paleoecological variability in an outcrop of Rio Bonito formation, Early Permian, Paraná Basin, Rio Grande do Sul, Brazil

“…Concepts provided by Gould and Delevoryas (1963), Staplin et al (1967), Taylor and Taylor (1993) and Balme (1995) were adopted for botanical affinity inferences. In relation to the algae and algae-like elements, taxonomic determinations and paleoecology were based mainly on Hemmer and Nygreen (1967), Loeblich and Tappan (1976), Tiwari et al (1994), Guy-Ohlson (1992), Elsik (1996), Batten (1996) and Servais (1996). For characterization and identification of paleosoils, megascopic and nomenclatural criteria outlined by Andreis (1981) were adopted.…”

Cretaceous and Cenozoic dinoflagellate cysts and other palynomorphs from the western and eastern margins of the Labrador–Baffin Seaway

“…Remarks. Described originally as representing pollen, Hemer & Nygreen (1967) considered Tetraporina to be an algal genus, and it has been considered generally to represent the acritarchs or algae since then. The above synopsis largely follows the emended diagnosis of Lindgren (1980).…”
