Late Jurassic salamanders from northern China

Nature, 2001
With ten extant families, salamanders (urodeles) are one of the three major groups of modern amphibians (lissamphibians). Extant salamanders are often used as a model system to assess fundamental issues of developmental, morphological and biogeographical evolution.

Late Jurassic magnetic polarity sequence

Earth and Planetary Science Letters, 1975
Abstract Polarity reversal sequences have been observed in the Brushy Basin Member of the Morrison Formation (Upper Jurassic, Kimmeridgian-Tithonian age) at two sites in western Colorado separated by 80 km. The two polarity reversal sequences display a good correlation of relative lengths and number of polarity intervals and thus may provide a ...

Late Jurassic paleoclimate of Central Africa

Palaeogeography, Palaeoclimatology, Palaeoecology, 2011
Abstract Paleopedology and geochemical analysis of Upper Jurassic deposits in the Stanleyville Group of Central Africa indicate harsh Late Jurassic paleoclimates in the interior of Gondwana. Subsurface samples collected from the Samba borehole near the center of the Congo Basin show only weak morphological evidence of pedogenesis, but are ...

Modelling Late Jurassic Milankovitch climate variations

Geological Society, London, Special Publications, 1995
Abstract Although largely circumstantial in character, evidence for orbitally-forced (Milankovitch) climate changes in Jurassic microrhythmic successions, such as those of the Lias and Kimmeridgian, is becoming more persuasive. We present here the results of experiments, using a general circulation model, testing ways in which ...

Late Jurassic Sauropods in Chilean Patagonia

Ameghiniana, 2015
Abstract. A description is provided of the first sauropod remains (i.e., isolated vertebrae and appendicular bones) from the Late Jurassic of Aysen, in Chilean Patagonia (Toqui Formation, late Tithonian). Although the bones found are fragmentary, they still allow the recognition of an unsuspected sauropod diversity for this period in South America. The
