An Enigmatic Cretaceous Beetle in Kachin Amber With Tentative Affinities to Pythidae (Coleoptera: Tenebrionoidea). [PDF]

open access: yesEcol Evol
We describe and illustrate a new tenebrionoid beetle from mid‐Cretaceous Kachin amber, Glyphonotum hsiaoi gen. et sp. nov. Based on morphological comparison and phylogenetic analyses, we tentatively place Glyphonotum in the extant family Pythidae, representing the first Mesozoic fossil of this family.

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

open access: yes, 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.

The Impetus for Bloom of Mesozoic Terrestrial Ecosystems in Northern China: Insights From Volcanic Nutrient and Harmful Element Delivery

open access: yesGeophysical Research Letters, Volume 50, Issue 9, 16 May 2023., 2023
Abstract The Jehol and Yanliao biotas of northern China, two world‐class Lagerstätten with abundant biomass and biodiversity, provide critical clues to Mesozoic terrestrial ecosystems. Their evolution is a response to the destruction of the North China craton. However, the impetus for the rapid bloom of the biotas remains a mystery.

Machine learning confirms new records of maniraptoran theropods in Middle Jurassic UK microvertebrate faunas

open access: yesPapers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023
Abstract Current research suggests that the initial radiation of maniraptoran theropods occurred in the Middle Jurassic, although their fossil record is known almost exclusively from the Cretaceous. However, fossils of Jurassic maniraptorans are scarce, usually consisting solely of isolated teeth, and their identifications are often disputed.

Insect herbivory immediately before the eclipse of the gymnosperms: The Dawangzhangzi plant assemblage of Northeastern China

open access: yesInsect Science, Volume 29, Issue 5, Page 1483-1520, October 2022., 2022
The Early Cretaceous terrestrial revolution was manifested by global shifts from gymnosperm‐ to angiosperm‐dominated floras. However, responses of insect herbivores to these changes remain unexamined. We evaluated 2 176 plant specimens representing 62 species/morphotypes from the 126‐122 Ma Dawangzhangzi plant assemblage of Northeastern China.

Phosphorus Variations in Volcanic Sequences Reveal the Linkage Between Regional Tectonics and Terrestrial Biota Evolution

open access: yesGeochemistry, Geophysics, Geosystems, Volume 23, Issue 8, August 2022., 2022
Abstract The Middle‒Late Mesozoic massive volcanism formed a considerable thickness of volcanic‐sedimentary strata in western Liaoning, northern China. Concomitantly, it elevated phosphorus (P) availability for the rapid bloom of the terrestrial Yanliao and Jehol biotas, which developed highly abundant biodiversity and biomass.
