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

The Anatomical Record, Volume 309, Issue 7, Page 1702-1712, July 2026.
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

The early origin of Iguanodontia: new insights into the macroevolution, diversity and biogeography of the clade

Palaeontology, Volume 69, Issue 2, 2026.
Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.

Review of the tetrapod skull–neck boundary: implications for the evolution of the atlas–axis complex

Biological Reviews, Volume 100, Issue 6, Page 2435-2470, December 2025.
ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

NEW THYREOPHORAN REMAINS WITH STEGOSAURIAN AFFINITIES FROM THE LOWER CRETACEOUS OF ARGENTINA

Publicación Electrónica de la Asociación Paleontológica Argentina
South American Mesozoic vertebrate fossils are key in contrasting the classic North American and European views of clades evolution. During the last decades, several relevant findings of stegosaurian remains from Argentina show a greater diversity than ...

Metatetrapous valdensisNopcsa, 1923 and the Presence of Ankylosaur Tracks (Dinosauria: Thyreophora) in the Berriasian (Early Cretaceous) of Northwestern Germany

Ichnos, 2014
Metatetrapous valdensis Nopcsa, 1923 from the late Berriasian of northwestern Germany was the first dinosaur ichnotaxon ever attributed to a thyreophoran trackmaker. However, the subsequent lost of the original material made this identification and the status of the ichnotaxon questionable for many subsequent authors.
