Widespread mermithid nematode parasitism of Cretaceous insects
Mermithid nematodes are obligate invertebrate parasites dating back to the Early Cretaceous. Their fossil record is sparse, especially before the Cenozoic, thus little is known about their early host associations.

An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

Abstract This study investigates the occurrence of osteomyelitis in non‐avian dinosaurs, focusing on the Ibirá locality, a site with a high incidence of this pathological condition. We analyzed six new osteopathic sauropod specimens from the Upper Cretaceous of Brazil.

Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Although there is poor outcrop in the area, the Daoxiang formation exposed in North Fujian has unique rock assemblage and metamorphism, and deformation characteristics show that the Daoxiang group does exist, and belongs to metamorphic rock of the ...
