The static life table analysis revealed the same general pattern of survivorship as tyrannosaurs including increased attrition before the attainment of full adult size, suggesting that most nonavian dinosaurs may have had a similar life history strategy.
Earliest known crown-group salamanders
The discovery of well-preserved Middle Jurassic salamander from China constitutes the earliest known record of crown-group urodeles (living salamanders and their closest relatives) and provides evidence to support the hypothesis that the divergence of the Cryptobranchidae from the Hynobiidae had taken place in Asia before the Middle Jurassic period.

The fossil record of tyrannosauroid theropods is marked by a substantial temporal and morphological gap between small-bodied, Barremian taxa, and extremely large-bodied taxa from the latest…
The distribution of integumentary structures in a feathered dinosaur
An enigmatic small theropod dinosaur is reported on that is covered with filamentous feather-like structures over its entire body.
Late Jurassic salamanders from northern China
The discovery of an extraordinary sample of salamander fossils from the Upper Jurassic of China is reported, providing compelling evidence for an Asian origin of Recent salamanders, as well as for an extensive and early radiation of several major lineages.
