Dinosaur biogeographic structure and Mesozoic continental fragmentation: a network-based approach [PDF]

, 2016
Aim: To reconstruct dinosaur macro-biogeographical patterns through the Mesozoic Era using a network-based approach. We test how continental fragmentation affected dinosaur macro-biogeographical structure and evolutionary rates.

The oldest record of North American Lychnothamnus (northeastern Sonora, Mexico): Implications for the evolution, ecology, and paleogeographic distribution of the genus [PDF]

, 2020
A large population of Late Cretaceous Lychnothamnus tenuis holding small sized gyrogonites are described after systematically sampling the Fronteras section in the Cabullona Group (northeastern Sonora, Mexico). This discovery represents the oldest record

A Re-Evaluation of the Chasmosaurine Ceratopsid Genus Chasmosaurus (Dinosauria: Ornithischia) from the Upper Cretaceous (Campanian) Dinosaur Park Formation of Western Canada. [PDF]

PLoS ONE, 2016
BACKGROUND:The chasmosaurine ceratopsid Chasmosaurus is known from the Upper Cretaceous (Campanian) Dinosaur Park Formation of southern Alberta and Saskatchewan. Two valid species, Chasmosaurus belli and C. russelli, have been diagnosed by differences in

Temporal range extension and evolution of the chasmosaurine ceratopsid ‘Vagaceratops’ irvinensis (Dinosauria: Ornithischia) in the Upper Cretaceous (Campanian) Dinosaur Park Formation of Alberta

Vertebrate Anatomy, Morphology, Palaeontology, 2019
The Dinosaur Park Formation (DPF) has a diverse assemblage of chasmosaurines currently represented by Chasmosaurus belli, C. russelli, Vagaceratops irvinensis, and Mercuriceratops gemini, and may also include remains possibly referable to Spiclypeus ...

A new Arctic hadrosaurid from the Prince Creek Formation (lower Maastrichtian) of northern Alaska [PDF]

Acta Palaeontologica Polonica, 2016
The Liscomb bonebed in the Price Creek Formation of northern Alaska has produced thousands of individual bones of a saurolophine hadrosaurid similar to Edmontosaurus; however, the specific identity of this taxon has been unclear, in part because the vast

Expanded concept of the milliped family Spirobolidae (Diplopoda: Spirobolida: Spirobolidea): Proposals of Aztecolini n. tribe and Floridobolinae/ini and Tylobolini n. stats.; re)descriptions of Floridobolus and F. penneri, both Causey, 1957, and F. orini n. sp.; hypotheses on origins and affinities [PDF]

, 2014
The endemic Floridian milliped genus, Floridobolus Causey, 1957, more closely related to tylobolinines in the western United States (US), Mexico, and Guatemala than syntopic spirobolines, is incorporated into Spirobolidae (Spirobolida: Spirobolidea ...

Coahuilasaurus lipani, a New Kritosaurin Hadrosaurid from the Upper Campanian Cerro Del Pueblo Formation, Northern Mexico

Diversity
The Late Cretaceous of Western North America (Laramidia) supported a diverse dinosaur fauna, with duckbilled dinosaurs (Hadrosauridae) being among the most speciose and abundant members of this assemblage.

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.
