Environmental and climatic proxies for the Cañadón Asfalto and Neuquén basins (Patagonia, Argentina): review of middle to upper jurassic continental and near coastal sequences [PDF]
, 2015 In this review, we include several proxies (sedimentology, palynology, invertebrates) from the Cañadón Asfalto and Neuquén basins, to infer the environments and regional climatic context during the Middle to Late Jurassic of Patagonia.

“Upper Jurassic” sediments of South Africa [PDF]
Nature, 1976 MARINE sedimentary rocks exposed near Knysna in the Cape Province of South Africa were assigned to the Upper Jurassic on the basis of a fragment of an ammonoid and seven previously undescribed species of ostracod1. A more thorough examination of the microfossils in these rocks indicates that this assignment was erroneous and that the beds are of Early ...

Evolution in Upper Jurassic Ammonites [PDF]
Evolution, 1959 Evolution in ammonites has been known for nearly a century. It was mainly under the influence of Charles Darwin (1859) that paleontologists began to look for successions of similar species and to connect these species into lineages. These early studies of evolution in ammonites are due to, e.g., Waagen (1869), Neumayr (1873) and Gemmellaro (1872-82 ...

ISOPOD TRACKWAYS FROM THE CRAYSSAC LAGERSTATTE, UPPER JURASSIC, FRANCE [PDF]
Palaeontology, 2005 Well-preserved arthropod trackways are described from the laminated limestones of the Crayssac Lagerstatte (south-west France, Lower Tithonian). They occur in sediments deposited in the temporary coastal mudflats of intertidal to supratidal zones. The trackways are referred to Pterichnus isopodicus isp.
