    Description: The incompleteness of the fossil record obscures the origin of many of the more derived clades of vertebrates. One such group is the Ichthyopterygia, a clade of obligatory marine reptiles that appeared in the Early Triassic epoch, without any known intermediates. Here we describe a basal ichthyosauriform from the upper Lower Triassic (about 248 million years ago) of China, whose primitive skeleton indicates possible amphibious habits. It is smaller than ichthyopterygians and had unusually large flippers that probably allowed limited terrestrial locomotion. It also retained characteristics of terrestrial diapsid reptiles, including a short snout and body trunk. Unlike more-derived ichthyosauriforms, it was probably a suction feeder. The new species supports the sister-group relationships between ichthyosauriforms and Hupehsuchia, the two forming the Ichthyosauromorpha. Basal ichthyosauromorphs are known exclusively from south China, suggesting that the clade originated in the region, which formed a warm and humid tropical archipelago in the Early Triassic. The oldest unequivocal record of a sauropterygian is also from the same stratigraphic unit of the region.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Motani, Ryosuke -- Jiang, Da-Yong -- Chen, Guan-Bao -- Tintori, Andrea -- Rieppel, Olivier -- Ji, Cheng -- Huang, Jian-Dong -- England -- Nature. 2015 Jan 22;517(7535):485-8. doi: 10.1038/nature13866.

    Description: Variation in daily activity patterns facilitates temporal partitioning of habitat and resources among species. Knowledge of temporal niche partitioning in paleobiological systems has been limited by the difficulty of obtaining reliable information about activity patterns from fossils. On the basis of an analysis of scleral ring and orbit morphology in 33 archosaurs, including dinosaurs and pterosaurs, we show that the eyes of Mesozoic archosaurs were adapted to all major types of diel activity (that is, nocturnal, diurnal, and cathemeral) and provide concrete evidence of temporal niche partitioning in the Mesozoic. Similar to extant amniotes, flyers were predominantly diurnal; terrestrial predators, at least partially, nocturnal; and large herbivores, cathemeral. These similarities suggest that ecology drives the evolution of diel activity patterns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmitz, Lars -- Motani, Ryosuke -- New York, N.Y. -- Science. 2011 May 6;332(6030):705-8. doi: 10.1126/science.1200043.

    Notes: [Auszug] The specimen was collected in 1989 from the Lower Triassic (Spathian) of Anhui Province, China, about 50 km southwest of the type locality of Chensaurus5'6, which is also Spathian7. Based on overall similarities, the specimen is tentatively identified as Chensaurus chaoxianensis (Chen) 1985 (ref. ...
