The morphology of the Jurassic fossil Archaeolus funestus Lin, 1986, which was previously placed in the extinct click-beetle subfamily Protagrypninae (Coleoptera: Elateridae), is revised based on a re-examination of the type specimen. The validity of Protagrypninae is discussed and further questioned, partly based on the newly observed characters i...

Abstract—The South Anyui Fold System was formed at the end of the Early Cretaceous at the site of a closed oceanic basin as a result of the collision of the Chukotka microcontinent with the structures of the active margin of the Siberian continent. There are two distinct stages in the tectonic history of the oceanic basin. At the first stage (Late ...

A new fossil mackerel shark, Pseudocorax kindlimanni sp. nov. (Lamniformes, Pseudocoracidae), is described from the Cenomanian Konservat-Lagerstätte of Haqel, Lebanon. The new species is based on the most complete fossil of this group to date, which comprises an associated tooth set of 70 teeth, six articulated vertebral centra, numerous placoid sc...

Adaptive radiations are hypothesized as a generating mechanism for much of the morphological diversity of extant species.1-7 The Cenozoic radiation of placental mammals, the foundational example of this concept,8,9 gave rise to much of the morphological disparity of extant mammals, and is generally attributed to relaxed evolutionary constraints fol...

A new genus and species of exaggerated antennae Coreidae is described from Myanmar amber of the Late Cretaceous (Cenomanian stage). Ferriantenna excalibur gen. et sp. nov. appears related to another Cretaceous coreid with exaggerated antennae, Magnusantenna Du & Chen, 2021, but can be differentiated by the fourth antennal segment which is short and...

Pterosaurs, which lived during the Mesozoic, were the first known vertebrates to evolve powered flight.1,2 Arboreal locomotion has been proposed for some taxa,3,4 and even considered to have played a role in the origin of pterosaur flight.5,6 Even so, there is still need for comprehensive quantitative ecomorphological analyses.3,4 Furthermore, skel...
A new genus and species of orussoid wasps, Cretorussus vilhelmseni gen. et sp. nov., is described based on new material from the mid-Cretaceous Burmese amber. Its wing venation and body characters lead us to emend the diagnosis of the family Burmorussidae. Cretorussus vilhelmseni gen. et sp. nov. is considered to be a specialized parasitic wasp of ...

A partial skeleton of a hybodontiform shark-like chondrichthyan from the Upper Jurassic Kimmeridge Clay Formation of Dorset, England, is described and designated as a new genus and species, Durnonovariaodus maiseyi gen. et sp. nov. The holotype and only known specimen, which is represented by disarticulated splanchnocranial elements with associated...
The extinct bark lice families †Archaeatropidae and †Empheriidae are considered closely related, yet distinct based upon an ever-dwindling set of morphological features. To help highlight the known variability in venation for described species, we present brief discussions for each Cretaceous species for these two families, illustrations of their w...
