Temporal Framework for the Yanliao Biota and Timing of the Origin of Crown Mammals
Earth and Planetary Science Letters, 2023 Establishing the temporal sequence of the Middle-Late Jurassic Yanliao Biota is essential as it anchors the timing of many key evolutionary innovations in vertebrates. Lack of sufficiently reliable high-precision ages of fossil-bearing horizons hinders our ability to reconstruct the tempo and mode of vertebrate evolution.

Climate-Change-Enhanced Habitat Diversification for the Middle Jurassic Yanliao Biota in East Asia [PDF]
National Science ReviewABSTRACT The Jurassic Period was characterized by the dominance of dinosaurs and the rise of early mammals, with the Yanliao Biota (∼167–157 Ma) in East Asia notable for its exceptional fossil preservation and diverse life forms. However, the drivers of the flourishing of the Yanliao Biota remain unclear.

Jurassic scorpionflies (Mecoptera) with swollen first metatarsal segments suggesting sexual dimorphism [PDF]
BMC Ecology and Evolution, 2021 Background Sexual dimorphism is widespread in insects. The certain specialized structures may be used as weapons in male–male combats or as ornaments to enhance mating opportunities.

Reconstructing Vegetation Biomass in the Middle Jurassic Yanliao Biota From Insect Fossil Assemblages [PDF]
National Science ReviewABSTRACT Quantifying vegetation biomass is essential for understanding the structure and energy balance of terrestrial ecosystems, yet robust estimates for deep-time ecosystems remain elusive. Most palaeovegetation proxies provide qualitative or relative signals but lack a direct connection to ecosystem-scale energetics.

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,

First Turtle Remains from the Middle-Late Jurassic Yanliao Biota, NE China
Science Technology and Engineering Journal (STEJ), 2021 The Middle-Late Jurassic Yanliao Biota, preceding the Early Cretaceous Jehol Biota in NE China has yielded a rich collection of plant, invertebrate and vertebrate fossils. But contrary to the Jehol Biota which is rich in freshwater vertebrates, in

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.
