Cretaceous Research, 2019 A detailed histological study of Antarctopelta oliveroi, from the Upper Cretaceous of Antarctica, is performed in order to increase our knowledge of the ankylosaur bone histology and its taxonomical and paleobiological implications.

Paleodiversity of Late Cretaceous Ankylosauria from Mexico and their phylogenetic significance [PDF]
Swiss Journal of Palaeontology, 2018 Isolated bones and osteoderms of ankylosaurian dinosaurs recovered from Late Cretaceous sediments of northern Coahuila, northeastern Mexico, have been identified as remains of nodosaurids. Here, we summarize these discoveries and provide a review on Mexican Ankylosauria from a taxonomic perspective.

Canadian Journal of Earth Sciences, 2001 Amongst the fossil material collected by the Sino-Soviet Expeditions (19591960) to the Alshan Desert, China, was a large, virtually complete ankylosaur skeleton. Gobisaurus domoculus gen. et sp. nov. closely resembles Shamosaurus scutatus, but is distinct in having an unfused basipterygoidpterygoid contact and elongate premaxillary processes of the ...

A new nodosaurid ankylosaur (Dinosauria: Thyreophora) from the Upper Cretaceous Menefee Formation of New Mexico [PDF]
PeerJ, 2018 Nodosauridae is a clade of armored dinosaurs with a rich fossil record and long history of study in North America. Nodosaurid fossils have been collected throughout the western United States and Canada. Here, we report three new nodosaurid specimens from

A new ankylosaurine dinosaur from the Judith River Formation of Montana, USA, based on an exceptional skeleton with soft tissue preservation [PDF]
Royal Society Open Science, 2017 The terrestrial Judith River Formation of northern Montana was deposited over an approximately 4 Myr interval during the Campanian (Late Cretaceous). Despite having been prospected and collected continuously by palaeontologists for over a century, few ...

Long bone histology and growth patterns in ankylosaurs: implications for life history and evolution. [PDF]
PLoS 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 new ankylosaurid dinosaur from the Upper Cretaceous (Kirtlandian) of New Mexico with implications for ankylosaurid diversity in the Upper Cretaceous of western North America. [PDF]
PLoS ONE, 2014 A new ankylosaurid (Ankylosauria: Dinosauria), Ziapelta sanjuanensis, gen. et sp. nov., is based on a complete skull, an incomplete first cervical half ring, a possible fragment of the second cervical half ring, and additional fragmentary osteoderms. The

Espinas dérmicas del dinosaurio anquilosaurio Polacanthus en las facies Weald de Salas de los Infantes (Burgos, España) [PDF]
Estudios Geologicos, 1999 Se describen elementos dermatoesqueléticos de un anquilosaurio procedentes del yacimiento de Fuente Espudia, cerca de Salas de los Infantes (Burgos). Los restos fósiles se localizan en arcillas rojas del Grupo Urbión, que forman parte de las facies Weald

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

The Paranasal Air Sinuses of Predatory and Armored Dinosaurs (Archosauria: Theropoda and Ankylosauria) and Their Contribution to Cephalic Structure [PDF]
The Anatomical Record, 2008 AbstractThe paranasal air sinuses and nasal cavities were studied along with other cephalic spaces (brain cavity, paratympanic sinuses) in certain dinosaurs via CT scanning and 3D visualization to document the anatomy and examine the contribution of the sinuses to the morphological organization of the head as a whole.
