Viviparity in a Triassic marine archosauromorph reptile
Eggs or embryos have been reported in various groups of fossil reptiles, where viviparity is a common mode of reproduction in aquatic taxa such as the ichthyopterygians, some groups of sauropterygians, mosasauroids, some taxa of choristoderans and certain protorosaurs. Here, we describe a complete embryo of a marine protorosaur, based...Chun, Li ; Rieppel, Olivier ; Fraser, Nicholas C

The skull displays a pronounced hammerhead shape that was hitherto unknown. The long, straight anterior edges of both upper and lower jaws were lined with batteries of chisel-shaped teeth, whereas the...Chun, Li ; Rieppel, Olivier ; Long, Cheng ; Fraser, Nicholas C

A long-snouted protorosaur from the Middle Triassic of southern China
A new protorosaur is described on the basis of a single specimen from the Ladinian of southern China. Although it has been greatly crushed, it still preserves clear details of the skull and axial skeleton. It possesses a neck that is longer than the trunk and is similar to tanystropheids...Fraser, Nicholas C ; Rieppel, Olivier ; Chun, Li
