A bony-crested Jurassic dinosaur with evidence of iridescent plumage highlights complexity in early paravian evolution [PDF]
Nature Communications, 2018 A number of paravian dinosaurs have been described from the Jurassic Yanliao biota, but these have tended to be morphologically similar to Archaeopteryx. Here, Hu. describe the new paravian dinosaur, Caihong juji gen. et sp. nov., which possesses a suite

The rise of predation in Jurassic lampreys [PDF]
Nature Communications, 2023 Lampreys, one of two living lineages of jawless vertebrates, are always intriguing for their feeding behavior via the toothed suctorial disc and life cycle comprising the ammocoete, metamorphic, and adult stages. However, they left a meager fossil record,

Tip dating supports novel resolutions of controversial relationships among early mammals. [PDF]
Proc Biol Sci, 2020 The estimation of the timing of major divergences in early mammal evolution is challenging due to conflicting interpretations of key fossil taxa. One contentious group is Haramiyida, the earliest members of which are from the Late Triassic.

A new neornithischian dinosaur from the Upper Jurassic Tiaojishan Formation of northern China [PDF]
PeerJThe Middle and Late Jurassic Yanliao Biota is different from other contemporaneous fossil assemblages in that it lacks neornithischian dinosaurs. Here, we report a new, early-diverging neornithischian, Pulaosaurus qinglong gen. et sp.
