Their regular variability in time and space was established and due to that stratigraphic division of the studied sediments was carried out. 11 species of 3 foraminifer genera and 9 species.

Abstract. In situ spores are described from Pennsylvanian-age sphenopsid cones. Spores from cones referable to the plant Calamites have been shown to resemble the dispersed spore genera Elaterites, Vestispora, or Calamospora at different stages in spore ontogeny.

Spores from some cones referable to the plant Sphenophyllum have ontogenetic stages resembling Vestispora Cited by: 8. Although not abundant, Vestispora (Wilson and Hoffmeister) Wilson and Venkatachala is a stratigraphically important genus of Carboniferous miospores (e.g., Ravn, ).

The morphology of Vestispora and Pteroretis Felix and Burbridge, the only similar genus, is unique among Carboniferous by: 1. For more than 70 years, the base of the Permian was recognized globally by a fusulinid biostratigraphic datum, the first occurrence (FO, which operationalizes its FAD = first appearance datum) of “Schwagerina,” which to many.

authors meant the FO of the inflated schwagerinids (e.g., Beede and Kniker, ). In order to establish a refined biostratigraphic subdivision and correlation of the Uppermost Carboniferous/Lower Permian Sakmarian and Artinskian faunas reveal an increasing divergence in species and genus composition.

Much later Dunbar and Skinner () restudied the type specimens of Ehrenberg's Borelis princeps and discovered they were significantly different from the highly inflated specimens.

McClendon in papers listed as “Contributions from the Zoological Laboratory of the Universityof Texas”. The stratigraphic significance of Pseudo-schwagerina was first discussed by Beede & Kniker () who pointed out that the first appearance of this genus coincided with the beginning of the Permian Period.

Subsequently, Dunbar & Skinner (), Kahler & Kahler (, etc.) and many others supported this view, contributing data on the geographic and.

History of Discovery: Paleoanthropologists actually found the first fossils belonging to P. boisei inbut it wasn’t until Mary Leakey’s discovery of the ‘Zinj’ skull (OH 5) that scientists knew what they had found was a new species.

‘Zinj’ became the type specimen for P. boisei and, soon after, arguably the most famous early human fossil from Olduvai Gorge in northern. botanical species are only a higher and more permanent class of variet-ies." He extends the same view to animals.
