O filogenezie dinozaurów ptasiomiedniczych (Ornithischia) [PDF]

open access: yes, 1985
The ornithischian dinosaurs are analysed using the cladistic methodology. The preferred hypothesis (see fig. 1) is that: 1. Ornithischia are monophyletic, 2. Ankylosauria are sister group of all other ornithischians, 3.

Insight on the anatomy, systematic relationships, and age of the Early Cretaceous ankylopollexian dinosaur Dakotadon lakotaensis [PDF]

open access: yesPeerJ, 2015
Knowledge regarding the early evolution within the dinosaurian clade Ankylopollexia drastically increased over the past two decades, in part because of an increase in described taxa from the Early Cretaceous of North America. These advances motivated the

The appendicular myology of Stegoceras validum (Ornithischia: Pachycephalosauridae) and implications for the head-butting hypothesis.

open access: yesPLoS ONE, 2022
In this study, we use an exceptional skeleton of the pachycephalosaur Stegoceras validum (UALVP 2) to inform a comprehensive appendicular muscle reconstruction of the animal, with the goal of better understanding the functional morphology of the ...
