A new uppermost Albian flora from Teruel province, northeastern Spain

A new isoetalean microsporophyll from the latest Albian of northeastern Spain: Diversity in the development and dispersal strategies of microspores

“…The lacustrine depositional basin was infilled with sediment, leading to a final colonization by terrestrial sun-loving or helophytic plants (Gomez et al 2009;Sender et al 2010). In Estercuel sedimentological studies suggest tidally influenced fluvial and swampy environments with low marine input demonstrated by the presence of dinoflagellate cysts and mytiloid bivalves (Sender et al 2012). …”

“…The beds bearing the studied isoetalean macroflora (level ET 2-1) correspond to grey claystone beds intercalated with medium-grained yellow sandstone and deposited in a tidally influenced fluvial sedimentary environment. This level also contains a very diverse and exceptionally well-preserved macro-and microfloral assemblages, which includes other isoetalean non-fertile leaves (Sender et al 2012). The overlying level ET 2-2 corresponds to black claystone with marine bivalves and less abundant plant remains.…”

“…1). The age of this unit in Estercuel has been established as latest Albian on the basis of the palynological assemblage (Sender et al 2012;Villanueva-Amadoz et al 2011).…”

Paisia, an Early Cretaceous eudicot angiosperm flower with pantoporate pollen from Portugal

“…The several species of Cretacaeiporites reported from the dispersed palynological assemblages of the São Julião shallow marine section near Ericeira, western Portugal (Horikx et al 2016), are all different from the in situ pollen of Paisia in the lack of spines. Other reports of pantoporate pollen from the Iberian Peninsula include rare occurrences of Penetetrapites from the late Albian of north-eastern Spain (Sender et al 2012). Early Cretaceous reports from other regions shows that although pantoporate pollen are not common they were already geographically widespread in the Aptian with occurrences in Egypt and Columbia (Ibrahim et al 2017) and by the Albian pantoporate pollen grains are diverse and almost global in distribution with occurrences in areas such as the former SSSR, Portugal, Egypt, Qatar, Sudan, Morocco, Tanzania, western Equatorial Africa, eastern North America, Brazil, Peru, and western China (e.g.…”

New plant fossils from the Lower Cretaceous of the Parnaíba Basin, Northeastern Brazil: Southern Laurasia links

“…Moreover, similar morphologies to that of Drewria, including "chevrons", characterize Welwitschia and the even now dubious Early Cretaceous monocot Acaceaephyllum Fontaine. However, the latter, like Gnetum, has a pinnate venation (Sender et al 2012).…”
