Divergent strategies in cranial biomechanics and feeding ecology of the ankylosaurian dinosaurs [PDF]
Scientific Reports, 2023 Ankylosaurs were important megaherbivores of Jurassic and Cretaceous ecosystems. Their distinctive craniodental anatomy and mechanics differentiated them from coexisting hadrosaurs and ceratopsians, and morphological evidence suggests dietary niche ...

Function and Evolution of Ankylosaur Dermal Armor [PDF]
Acta Palaeontologica Polonica, 2010 Ankylosaurs have spike-, plate-, and club-shaped osteoderms probably used as defensive and/or offensive weapons. Previous studies have proposed the evolution and function of small ankylosaur osteoderms, but histological variations in their defensive weapons are little known.

A new Cretaceous thyreophoran from Patagonia supports a South American lineage of armoured dinosaurs [PDF]
Scientific Reports, 2022 The early evolution of thyreophoran dinosaurs is thought to have occurred primarily in northern continents since most evidence comes from the Lower and Middle Jurassic of Europe and North America.

Microstructure and development of the dermal ossicles of Antarctopelta oliveroi (Dinosauria, Ankylosauria): A complex morphogenetic system deciphered through three‐dimensional X‐ray microtomography [PDF]
Journal of Anatomy, Volume 247, Issue 3-4, Page 665-681, September/October 2025.Series of images of the dermal ossicle of Antarctopelta oliveroi (Dinosauria, Ankylosauria) illustrating (A) the 3D distribution of the vascular mesh in the ossicle; (B) the large volume of the numerous cells in periphery; (C) the radial orientation of the fiber bundles in the main core of the osteoderm (called basal plate); (D) the orthogonal ...

China shares fossil treasures with the world [PDF]
The Anatomical Record, Volume 308, Issue 10, Page 2806-2812, October 2025.Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...

New teeth of nodosaurid ankylosaur from the Lower Cretaceous of Southern England [PDF]
Acta Palaeontologica Polonica, 2013 We present new nodosaurid teeth from the Valanginian of Bexhill, Sussex and the Barremian of the Isle of Wight, the first from the Lower Cretaceous of the United Kingdom. Teeth found during the mid-1800s from the Valanginian and ascribed to the nodosaurid Hylaeosaurus are probably from sauropod dinosaurs.
