Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Late Mesozoic marine Antarctic fishes: future perspectives based on the newly collections recovered in the Ameghino and López de Bertodano Formations [PDF]

open access: yesResearch & Knowledge, 2017
Nowadays, notothenioids are the teleostean group that dominates marine Antarctic waters. However, during the Mesozoic a diverse ichthyofauna inhabited the sea that surrounded Antarctic.

End-Cretaceous extinction in Antarctica linked to both Deccan volcanism and meteorite impact via climate change

open access: yesNature Communications, 2016
The cause of the end-Cretaceous (KPg) mass extinction is still debated due to difficulty separating the influences of two closely timed potential causal events: eruption of the Deccan Traps volcanic province and impact of the Chicxulub meteorite. Here we

British Cretaceous Nuculidæ [PDF]

open access: yesQuarterly Journal of the Geological Society of London, 1884
T he Nuculæ and Ledæ with their allies, are now generally separated from the Arcidæ, and in a palæontological point of view this separation is amply justified; for their distinctive characters have persisted throughout many geological periods, and may be recognized to some extent ...

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
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

American Cretaceous Flora [PDF]

open access: yesNature, 1881
IN several of the interesting and valuable papers on the Tertiary flora which Mr. J. Starkie Gardner has contributed to the English journals he has referred to the fossil plants in our Cretaceous rocks as representing a flora really Tertiary in character; and, influenced by the modern aspect of the plants contained in our Dakota group (Lower Cretaceous)
