First Occurrence of Gargoyleosaurus (Dinosauria: Ankylosauria) in Utah
, 2023 Ankylosaurs are a group of armored dinosaurs that likely evolved sometime during the Middle Jurassic period and survived until the extinction of all non-avian dinosaurs at the end of the Cretaceous period. Ankylosaur material from the Jurassic is rare, and often fragmentary, leading to confusion about the phylogenetic placements of various Late ...

The dentary of hadrosauroid dinosaurs: evolution through heterochrony
Palaeontology, Volume 66, Issue 5, September/October 2023., 2023 Abstract The near‐global distribution of hadrosaurid dinosaurs during the Cretaceous has been attributed to mastication, a behaviour commonly recognized as a mammalian adaptation. Its occurrence in a non‐mammalian lineage should be accompanied by the evolution of several morphological modifications associated with food acquisition and processing.

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022 Abstract Little is known about the large‐scale evolutionary patterns of skull size relative to body size, and the possible drivers behind these patterns, in Archosauromorpha. For example, the large skulls of erythrosuchids, a group of non‐archosaurian archosauromorphs from the Early and Middle Triassic, and of theropod dinosaurs are regarded as ...

, 2022 Ankylosauria indet. (Fig. 23 A-C) DESCRIPTION The ankylosaurs are only represented in Angeac-Charente by a single tooth (ANG15-3980) and an osteoderm (ANG18- 6585). The tooth (Fig. 23A, B) was collected in 2015 from the unit 3 of the CG3 plot. The osteoderm (Fig.

A reassessment of the purported ankylosaurian dinosaur Bienosaurus lufengensis from the Lower Lufeng Formation of Yunnan, China [PDF]
Acta Palaeontologica Polonica, 2019 The earliest definitive ornithischian dinosaurs are from the Early Jurassic and are rare components of early dinosaur faunas. The Lower Lufeng Formation (Hettangian–Sinemurian) of Yunnan Province, China, has yielded a diverse Early Jurassic terrestrial ...

Notice of nodosaur (Dinosauria, Ankylosauria) remains from the mid-Cretaceous of Cambridge, England, with comments on cervical half-ring armour [PDF]
Proceedings of the Geologists' Association, 2014 Three pieces from cervical half-rings of an immature nodosaur, part of a nodosaurid presacral rod and some post-cranial osteoderms from the Cretaceous of Cambridge were studied at the Booth Museum of Natural History, Brighton, UK. Two of the three half-ring elements show dorsal ridge morphologies distinct from each other, and all three have unfused ...

Unusual cranial and postcranial anatomy in the archetypal ankylosaur Ankylosaurus magniventris
FACETS, 2017 Ankylosaurus magniventris is an iconic dinosaur species often depicted in popular media. It is known from relatively fragmentary remains compared with its earlier and smaller relatives such as Euoplocephalus and Anodontosaurus.
