The braincase of Bissektipelta archibaldi — new insights into endocranial osteology, vasculature, and paleoneurobiology of ankylosaurian dinosaurs [PDF]

open access: yes, 2020
We describe in detail three braincases of the ankylosaur Bissektipelta archibaldi from the Late Cretaceous (Turonian) of Uzbekistan with the aid of computed tomography, segmentation, and 3D modeling. Bissektipelta archibaldi is confirmed as a valid taxon

A new armored dinosaur with double cheek horns from the early Late Cretaceous of southeastern China

open access: yesVertebrate Anatomy, Morphology, Palaeontology

Long bone histology and growth patterns in ankylosaurs: implications for life history and evolution.

open access: yesPLoS ONE, 2013
The ankylosaurs are one of the major dinosaur groups and are characterized by unique body armor. Previous studies on other dinosaur taxa have revealed growth patterns, life history and evolutionary mechanisms based on their long bone histology.

A proxy for brain‐to‐endocranial cavity index in non‐neornithean dinosaurs and other extinct archosaurs

open access: yesJournal of Comparative Neurology, Volume 532, Issue 3, March 2024.
Illustration of the endocranial doming, which can provide a proxy for the brain‐to‐endocranial cavity index, using the endocast of an adult of the iguanodont dinosaur Proa valdearinnoensis as an example. Abstract Although the brain fills nearly the entire cranial cavity in birds, it can occupy a small portion of it in crocodilians.

Figure 1 in A redescription of the skull of Euoplocephalus tutus (Archosauria: Ornithischia): a foundation for comparative and systematic studies of ankylosaurian dinosaurs

open access: yes, 2003
Figure 1. Phylogeny of the Ankylosauria, providing the genealogical context for the taxa discussed in the text (after Vickaryous et al., 2001b). Explanation of nodes: node (1) Ankylosauria; node (2) Nodosauridae; node (3) Ankylosauridae; node (4 ...

Convoluted nasal passages function as efficient heat exchangers in ankylosaurs (Dinosauria: Ornithischia: Thyreophora).

open access: yesPLoS ONE, 2018
Convoluted nasal passages are an enigmatic hallmark of Ankylosauria. Previous research suggested that these convoluted nasal passages functioned as heat exchangers analogous to the respiratory turbinates of mammals and birds. We tested this hypothesis by

HISTOLOGY OF DERMAL OSSIFICATIONS IN AN ANKYLOSAURIAN DINOSAUR FROM THE LATE CRETACEOUS OF ANTARCTICA

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
Ankylosaurian remains from the Late Cretaceous (Campanian) Santa Marta Formation of the James Ross Island in the Antarctic Peninsula include several types of armour, the most abundant being tiny, button-like ossicles (less than 5 mm in diameter).
