A variety of paleogeographic reconstructions have been published, with applications ranging from paleoclimate, ocean circulation and faunal radiation models to resource exploration; yet their uncertainties remain difficult to assess as they are generally presented as low-resolution static maps. We present a methodology for ground-truthing the digital Palaeogeographic Atlas of Australia by linki...

Benthic foraminifera are significant indicators of habitat changes and useful for paleoenvironmental reconstruction. During the Permian period, variation in species, individual sizes, morphological characteristics different assemblages, such as fusulinids, is a clue to paleoecological interpretations. The eastern part Sichuan Basin, located near equator middle Permian, Guadalupian was precipita...

Assemblages of agglutinated foraminifers ranging from the Aptian to the lower Eocene were studied in the Bile Karpaty unit. One hundred ninety species (43 of them undetermined) were studied taxonomically. The *species Glomospira s traniki and ~ u r r i t e l l e l l a reversa are 'new. Several species of the abyssal "Krashenimikov" fauna (Buzasina inflata, Haplophragmoides decussatus, H . perex...

Abstract A relatively complete conodont record from Famennian to the Mississippian/Pennsylvanian boundary was investigated in Anarak section, Central Iran. The studied interval belongs Bahram, Shishtu, Ghaleh and Absheni formations. part of section (Bahram Formation) ranges Palmatolepis triangularis Zone into Bispathodus ultimus Zone.

Abstract In Egypt, Wadi Qena Middle Eastern Desert, Paleogene successions exposed at Hawashiya and Abu Had sections from north to south were measured comprehensively investigated for their foraminiferal content. The Dakhla, Tarawan, Esna formations make up the sections. studied are subdivided into six biozones; they five zones of Late Paleocene ( Igorina albeari subzone (P3b), G. Globanomalina ...
