The first Elcanidae (Orthoptera, Elcanoidea) from the Daohugou fossil bed of northeastern China [PDF]

open access: yesZooKeys, 2019
A new species of Elcanidae (Orthoptera, Elcanoidea), Parelcana pulchmacula sp. nov., is described based on four new specimens from the Middle Jurassic Jiulongshan Formation of northeastern China. The new species differs from all other known Archelcaninae

European Arid Anomaly Explained With Southward Drift of Eurasia During the Late Jurassic Polar Shift [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
The sedimentary successions of several basins in Europe show evidence of widespread Late Jurassic aridification that is considered a long-standing conundrum in paleoclimate modeling.

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

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.

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.

Variable preservation potential and richness in the fossil record of vertebrates

open access: yesPalaeontology, Volume 63, Issue 2, Page 313-329, March 2020., 2020
Abstract Variation in preservation and sampling probability clouds our estimates of past biodiversity. The most extreme examples are Lagerstätten faunas and floras. Although such deposits provide a wealth of information and represent true richness better than other deposits, they can create misleading diversity peaks because of their species richness ...

Systematics, biomechanics and ecology of mammals of the Kilmaluag Formation (Jurassic) of Scotland [PDF]

open access: yes, 2020
The Middle Jurassic was a pivotal time in the macroevolution of mammals. The earliest mammaliaform branches flourished alongside non-mammalian cynodonts (tritylodontids) and the first crown group mammals. Recent fossil material from China suggests not
