the kopet-dagh basin extended in the north and north east of iran and consists of marine strata from middle jurassic to paleogene time. abtalkh formation is one of the thickest lithostratigraphic units of cretaceous in the kopet-dagh basin and is composed of light gray, green to bluish marl and silty marl. the abtalkh formation conformably overlies the marls and chalky limestones of the abderaz...

Macrofossil analysis of a composite 19 m long sediment core from Rano Raraku Lake (Easter Island) was related to litho-sedimentary and geochemical features of the sediment. Strong stratigraphical patterns are shown by indirect gradient analyses of the data. The good correspondence between the stratigraphical patterns derived from macrofossil (Correspondence Analysis) and sedimentary and geochem...

Abstract Within the UNESCO Škocjan Caves, detailed geological structural mapping of cave passages and surface above revealed interesting structural-lithological characteristics two major collapse dolines, Velika Dolina Mala Dolina. As a result karst processes effects formation older—stratigraphically lower—carbonates Sežana Formation (K 2 2−4 ) crop out at surface, underlying rocks younger Lipi...

Farmerella exoporosa gen. et sp.nov. is described from cold-water Permian (Bernacchian-Lymingtonian) rocks of Tasmania. The new taxon is essentially homeomorphic with Glendonia McClung & Armstrong, 1978. However, Glendonia possesses a micro-ornament of low, elongate microspines behind shallow, elongate grooves, whereas Farmerella gen.nov. (as in Notospirifir Harrington, 1955) has deep, elongate...

The Geological Survey of the Netherlands (GSN) systematically produces 3D stochastic geological models of the Dutch subsurface. These voxel models are regarded essential in answering subsurface-related questions on, for example, aggregate resource potential, groundwater flow, land subsidence hazard and the planning and realization of large-scale infrastructural works. GeoTOP is the most recent ...

The Brazilian Quaternary terrestrial Carnivora are represented by the following families: Canidae, Felidae, Ursidae, Procyonidae Mephitidae and Mustelidae. Their recent evolutionary history in South America is associated with the uplift of the Panamanian Isthmus, and which enabled the Great American Biotic Interchange (GABI). Here we present new fossil records of Carnivora found in a cave in Au...
