Craniodental anatomy in Permian-Jurassic Cynodontia and Mammaliaformes (Synapsida, Therapsida) as a gateway to defining mammalian soft tissue and behavioural traits [PDF]

open access: yes, 2023
Mammals are diagnosed by more than 30 osteological characters (e.g. squamosal-dentary jaw joint, three inner ear ossicles, etc.) that are readily preserved in the fossil record.

Theropod guild structure and the tyrannosaurid niche assimilation hypothesis: implications for predatory dinosaur macroecology and ontogeny in later Late Cretaceous Asiamerica. [PDF]

open access: yes, 2021
Well-sampled dinosaur communities from the Jurassic through the early Late Cretaceous show greater taxonomic diversity among larger (>50 kg) theropod taxa than communities of the Campano-Maastrichtian, particularly to those of eastern/central Asia and ...

Marine and Non-marine Jurassic: Boundary Events and Correlation [PDF]

open access: yes, 2006
A variety of experiences and approaches have been accumulated which resulted in the availability of highly precise correlation within the marine Jurassic, though correlation of marine Triassic/Juurassic, Jurassic/Cretaceous boundaries and particularly ...

Mastigocoleidae fam. nov., a New Mesozoic Beetle Family and the Early Evolution of Dryopoidea (Coleoptera) [PDF]

open access: yes, 2023
With some 3,700 described species, Dryopoidea are a moderately diverse superfamily of beetles whose position within basal Polyphaga has been historically difficult to elucidate.

Biogeographic history of Palearctic caudates revealed by a critical appraisal of their fossil record quality and spatio-temporal distribution [PDF]

open access: yes, 2022
Altres ajuts: CERCA Programme/Generalitat de CatalunyaThe disjunct geographical range of many lineages of caudates points to a complex evolutionary and biogeographic history that cannot be disentangled by only considering the present-day distribution of ...

Experimental investigation of insect deposition in lentic environments and implications for formation of Konservat Lagerstätten [PDF]

open access: yes, 2020
Terrestrial insects are often remarkably well preserved in lacustrine Konservat Lagerstätten. However, the assumption that carcasses should sink fast through the water column seems contradictory as this scenario is unlikely due to excessive buoyancy and ...

Mesozoic basins and associated palaeogeographic evolution in North China

open access: yesJournal of Palaeogeography, 2015
In North China, the Mesozoic terrestrial basins, sedimentary palaeogeography and tectonic settings involved five evolutionary stages: (1) the Early‒Middle Triassic, (2) the Late Triassic to Early‒Middle Jurassic, (3) the Late Jurassic to early Early ...

Pterosaur integumentary structures with complex feather-like branching [PDF]

open access: yes, 2018
Pterosaurs were the first vertebrates to achieve true flapping flight, but in the absence of living representatives, many questions concerning their biology and lifestyle remain unresolved.

Mesozoic mammaliaforms illuminate the origins of pelage coloration [PDF]

open access: yes
Pelage coloration, which serves numerous functions, is crucial to the evolution of behavior, physiology, and habitat preferences of mammals. However, little is known about the coloration of Mesozoic mammaliaforms that coevolved with dinosaurs.

Insecta Orthoptera: a bibliometric review of papers from the Scopus database published in English for the period of 1986-2021 [PDF]

open access: yes, 2023
Today, climate change, an increase in anthropogenic factors, and changes in the natural environment have an adverse effect on insect diversity due to the changing climes around the world.
