Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

open access: yesJournal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

The Duntulm sauropod tracksite and environmental partitioning in Middle Jurassic dinosaurs on the Isle of Skye, Scotland

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract Dinosaur fossils from the Isle of Skye (Scotland, UK), particularly the abundant trace fossil record, provide a window into dinosaur evolution during the poorly known Middle Jurassic. Here we present a comprehensive description of the Duntulm tracksite from Cairidh Ghlumaig Bay, using aerial photography to provide whole site maps, catalogue ...

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

open access: yesThe 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

Back from the dead: Thyreophora cynophila (Panzer, 1798) (Diptera: Piophilidae) ‘globally extinct’ fugitive in Spain

open access: yesSystematic Entomology, 2010
We report on a sensational find in central Spain of six specimens of Thyreophora cynophila (), a colourful, strange‐looking piophilid fly living on carcasses of big mammals in advanced stages of decay.

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

open access: yesPalaeontology, 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

open access: yesBiological 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.

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

open access: yesIchnos, 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.

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

open access: yesPublicación 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 ...
