Late Carboniferous miospores from the Tarma Formation, Pongo de Mainique, Peru

Paleogeography of the upper Paleozoic basins of southern South America: An overview

“…The Tarma Group has been assigned, on the basis of marine invertebrates, to the Late Carboniferous (sensu lato), but more recent palynological studies constrain the age of the uppermost Tarma levels to the Moscovian (Azcuy et al, 2002). Toward the Altiplano in Bolivia, Early Pennsylvanian sedimens are represented by the Yaurichambi Formation, which filled an irregular topography formed after Middle Carboniferous tectonic movements .…”

“…The rich paleontological record many of these basins have yielded makes them even more significant. Different biostratigraphic schemes have been developed from the study of fossiliferous assemblages and used in regional correlations among different Gondwana basins, because they constitute essential tools to constrain the age of major geologic events (Archangelsky et al, 1996a,b;Díaz Martínez et al, 2000;Azcuy et al, 2002;Gutiérrez et al, 2003;Souza and Marques-Toigo, 2003).…”

First Palynological Record from the Upper Carboniferous/Lower Permian Succession in West Beni Suef Basin, Egypt, with Paleoecological and Paleogeographical Implications

“…The miospore genera employed in the present study are organized in Table 1 approximately according to the suprageneric classification of Dettmann (1963) as modified by Neves & Owens (1966) and Smith & Butterworth (1967) but his terms are omitted to save space. The botanical affinities of the encountered taxa, to reconstruct the paleovegetation, are mentioned based on the available data obtained from Ravn (1986), Balme (1995), Azcuy et al (2002), Lindström (2003), Traverse (2007), Boardman et al (2012), Waksmundzka (2014), Di Pasquo & Iannuzzi (2015) and Mahesh et al (2016).…”

Palinología de la Formación Andapaico (Cisuraliano-Guadalupiano), Precordillera Central Sanjuanina (Argentina): consideraciones bioestratigráficas regionales

“…No se observan poblaciones independientes del conjunto, lo que permite considerar a las todas formas comprendidas entre ambos tipos morfológicos (oval/longitudinal a oval/transverso) como ejemplares de una misma especie. también fueron comparados los ejemplares con diversos morfotipos de Illinites unicus (Azcuy et al, 2002), aunque esta especie presenta una estría central subecuatorial, de la cual se ramifican estrías menores generando una división del cuerpo asimétrica. En los ejemplares aquí estudiados se observa una calle central horizontal ecuatorial, que bisecta al cuerpo generando 2 tenias equidimensionales, sin divisiones menores.…”
