Abstract:

Carboniferous and Permian carbonate sequences in Japan are most completely preserved in the Akiyoshi Limestone in the Akiyoshi Terrane (Permian accretionary complex), Southwest Japan. The studied Sakmarian to lower Kungurian sequence is biostratigraphically divided into six zones: Globifusulina nux Zone and Globifusulina krotowi Zone (Sakmarian), Chalaroschwagerina vulgaris Zone (lower to middle Artinskian), Paraleeina magna Zone (upper Artinskian), Pamirina leveni Zone (uppermost Artinskian), and Miselllina dyhrenfurthi Zone (lower Kungurian) based on stratigraphic distribution and species co

aximum-marine flooding levels and marine-condensed sections from uppermost Carboniferous and Lower Permian fourth-order (0.1-1 m.y.) depositional sequences of the North American midcontinent reveal a rich stratigraphic succession of species of Streptognathodus and Sweetognathus conodonts that permits high-precision correlation of the Carboniferous-Permian boundary as well as the Asselian-Sakmarian and Sakmarian-Artinskian boundaries. Eleven new species of Streptognathodus are described: Streptognathodus binodosus, S. denticulatus, S. elongianus, S. florensis, S. lineatus, S. nevaensis, S. post

Abstract:

A preliminary palynological study of Beacon Supergroup sedimentary rocks exposed at Milorgfjella, Dronning Maud Land, has yielded a relatively rich and well preserved palynoflora dominated by spores and pollen grains, but also including acritarchs and green algae. The palynoflora is dominated by the pterophyte spores Punctatisporites gretensis, Punctatisporites parvus, Granulatisporites spp., Microbaculispora tentula Horriditriletes spp. and Verrucosisporites andersonii, and the gymnosperm pollen grains Plicatipollenites spp. and Cannanoropollis spp. Also present are the lycopod spore Jayantis

Abstract:

Five new species of Early Permian (late Sakmarian to Kungurian) colonial corals from eastern Nevada and southeastern California, one assigned to a new genus, are described and illustrated.

Abstract:

Familial groupings of two upper Paleozoic superfamilies of Goniatitina, Marathonitaceae and Cyclolobaceae, are reviewed. It is concluded that the Marathonitidae gave rise to the Hyattoceratidae and together constitute the Marathonitaceae. Eohyattoceras n. gen. is the Lower Permian ancestral hyattoceratid, and is represented by two new species, the type, E. gerthi from the Roadian of Timor, and E. leei from the Sakmarian of Nevada. An advanced marathonitid from the Lower Permian (Roadian) of Timor is described as Cardiella martodjojoi n. sp.Two lineages within the exclusively Permian family Cyc

Abstract:

Upper Carboniferous and Lower Permian shallow marine rocks in the Pequop Mountains of northeastern Nevada contain an abundance of fossils, especially fusulinids and fasciculate corals. As the composite stratigraphic section in this area represents the most nearly complete sequence of this type of corals anywhere in the Cordilleran miogeocline, this study was undertaken to document their occurrence sequentially. This information should be useful for comparison with other sections in the miogeocline containing similar corals.Only one species of Durhamina is present in the Gzhelian rocks. Durhami
