Trilobites dominantly of middle Cambrian (Miaolingian Series, Wuliuan Stage) age are described from the Telt Bugt Formation Daugaard-Jensen Land, western North Greenland (Laurentia), which is a correlative Cape Wood Inglefield Land and Ellesmere Island, Nunavut. Four biozones recognised in representing Delamaran Topazan regional stages USA. The basal Plagiura–Poliella Biozone, with Mexicella cf...

Abstract Acritarch biostratigraphic and δ 13 C chemostratigraphic data from the Krol A Formation in Solan area (Lesser Himalaya, northern India) are integrated to aid inter-basinal correlation of early–middle Ediacaran strata. We identified a prominent negative excursion (likely equivalent EN2 lower Doushantuo Yangtze Gorges South China), over dozen species acanthomorphs (including two new spec...

Twenty surface samples were taken from road cuttings along Okpekpe and Imiegba areas located in Benin Flank of Anambra Basin, Nigeria with an aim to establish the biozones, age paleodepositional environments Mamu Formation. Using palynological laboratory standard procedures, shale collected Formation study area prepared analyzed. The recovered marker pollens, spores dinoflagellate cysts are Mil...

Mallines are Patagonian wetlands characterized by permanent waterlogging on its soils, sustaining small shallow lakes that hosts a vast biodiversity. In these ecosystems, aquatic plants (i.e. macrophytes) develop different life forms adapted to humid conditions, allowing them regulate the physical and chemical conditions of mallín. A distinctive characteristic Patagonia is exponential west-east...

The Mishrif Formation represents a carbonate succession that deposited in major parts of the Arabian Plate during Cenomanian stage. formation is rich fossils including foraminifera, rudists, and algae. This study includes determination biozones biostratigraphic limits three boreholes sections (Cenomanian) from Majnoon Zubair oil fields southern Iraq within Mesopotamian Basin. A new scheme intro...

Gundis, or comb rats, are rodents of the family Ctenodactylidae. Extant gundis are restricted to Africa and represent a vestige of the diversity that the ctenodactylids attained at both palaeoecological and palaeobiogeographical levels. Here, we present an updated review of the Ctenodactylidae from the Valley of Lakes, Mongolia, based on the study of large collections now available. We have rec...
