Abrupt and gradual extinction among Late Permian land vertebrates in the Karoo basin, South Africa.
The Karoo basin of South Africa exposes a succession of Upper Permian to Lower Triassic terrestrial strata containing abundant terrestrial vertebrate fossils. Paleomagnetic/magnetostratigraphic and carbon-isotope data allow sections to be correlated across the basin. With this stratigraphy, the vertebrate fossil data show a gradual extinction in the Upper Permian punctuated by an enhanced extin...
متن کاملPre-drill Groundwater Geochemistry in the Karoo Basin, South Africa.
Enhanced production of unconventional hydrocarbons in the United States has driven interest in natural gas development globally, but simultaneously raised concerns regarding water quantity and quality impacts associated with hydrocarbon extraction. We conducted a pre-development assessment of groundwater geochemistry in the critically water-restricted Karoo Basin, South Africa. Twenty-two sprin...
متن کاملThe Karoo Array Telescope
The Karoo Array Telescope (KAT) will be a “1% demonstrator” for the SKA, located in a radio quiet reserve in the Karoo region of the Northern Cape province of South Africa. Besides developing technologies for the SKA project, the KAT will perform wide-field surveys that will be precursors to the eventual SKA products. The nominal specification for the KAT are listed, and the proposed science th...
متن کاملThe first megatheropod tracks from the Lower Jurassic upper Elliot Formation, Karoo Basin, Lesotho
A palaeosurface with one megatheropod trackway and several theropod tracks and trackways from the Lower Jurassic upper Elliot Formation (Stormberg Group, Karoo Supergroup) in western Lesotho is described. The majority of the theropod tracks are referable to either Eubrontes or Kayentapus based on their morphological characteristics. The larger megatheropod tracks are 57 cm long and have no Sout...
متن کاملThe Earliest Post-Paleozoic Freshwater Bivalves Preserved in Coprolites from the Karoo Basin, South Africa
BACKGROUND Several clades of bivalve molluscs have invaded freshwaters at various times throughout Phanerozoic history. The most successful freshwater clade in the modern world is the Unionoida. Unionoids arose in the Triassic Period, sometime after the major extinction event at the End-Permian boundary and are now widely distributed across all continents except Antarctica. Until now, no freshw...
