Plant remains from the Middle–Late Jurassic Daohugou site of the Yanliao Biota in Inner Mongolia, China

open access: yesActa Palaeobotanica, 2017
A late Middle–early Late Jurassic fossil plant assemblage recently excavated from two Callovian– Oxfordian sites in the vicinity of the Daohugou fossil locality in eastern Inner Mongolia, China, was analysed in detail.

An Updated Review of the Middle‐Late Jurassic Yanliao Biota: Chronology, Taphonomy, Paleontology and Paleoecology

open access: yesActa Geologica Sinica - English Edition, 2016
Abstract The northeastern Chinese Yanliao Biota (sometimes called the Daohugou Biota) comprises numerous, frequently spectacular fossils of non‐marine organisms, occurring in Middle‐Upper Jurassic strata in western Liaoning, northern Hebei, and southeastern Inner Mongolia.

New spiders (Araneae: Palpimanoidea) from the Jurassic Yanliao Biota of China [PDF]

open access: yesJournal of Systematic Palaeontology, 2019
Several new spider specimens, belonging to the superfamily Palpimanoidea, are described from the Middle–Upper Jurassic Haifanggou Formation (early assemblage of the Yanliao Biota) of Inner Mongolia, China. Two new genera and species, and a new species in the genus Sinaranea Selden, Huang & Ren, 2008, are described. Caestaranea jurassica gen. et sp.

New information on the Wukongopteridae (Pterosauria) revealed by a new specimen from the Jurassic of China [PDF]

open access: yesPeerJ, 2016
The Wukongopteridae is an important pterosaur group discovered from Yanliao Biota, because it combines character states seen in non-pterodactyloid and pterodactyloid pterosaurs.

A bony-crested Jurassic dinosaur with evidence of iridescent plumage highlights complexity in early paravian evolution [PDF]

open access: yesNature 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

Investigating the Morphogenesis and Replacement of Lamprey Toothlets Using Synchrotron Imaging. [PDF]

open access: yesJ Morphol
Toothlet replacement is a conserved feature in lampreys. We describe the mechanism at tissue level and quantify the determining factors, thus providing the basis for studies into a deep homology of cyclostome toothlets and gnathostome teeth. ABSTRACT Teeth are a key innovation that underpinned the adaptive radiation of jawed vertebrates; however, their

Earliest filter-feeding pterosaur from the Jurassic of China and ecological evolution of Pterodactyloidea [PDF]

open access: yesRoyal Society Open Science, 2017
Pterosaurs were a unique clade of flying reptiles that were contemporaries of dinosaurs in Mesozoic ecosystems. The Pterodactyloidea as the most species-diverse group of pterosaurs dominated the sky during Cretaceous time, but earlier phases of their ...

Tip dating supports novel resolutions of controversial relationships among early mammals. [PDF]

open access: yesProc 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.
