Morphology forms the most fundamental level of data in vertebrate palaeontology because it
is through interpretations of morphology that taxa are identified, creating the basis for broad …

Armoured dinosaurs are well known for their evolution of specialized tail weapons—paired
tail spikes in stegosaurs and heavy tail clubs in advanced ankylosaurs. Armoured dinosaurs …

The famous bone beds of the Morrison Formation, formed one hundred and fifty million
years ago and running from Wyoming down through the red rock region of the American …

Eurypoda, the major radiation of armoured dinosaurs, comprises the ankylosaurs and their
sister group, the stegosaurs. As the earliest-branching major clade of ornithischian …

The stegosaurs are some of the most easily recognizable dinosaurs, but are surprisingly
rare as fossils. Consequently much remains unknown about their palaeobiology, and every …

Ornithischian dinosaurs were ecologically prominent herbivores of the Mesozoic Era that
achieved a global distribution by the onset of the Cretaceous. The ornithischian body plan is …

Scelidosaurus fossils were first discovered during the commercial quarrying of the Liassic
sea-cliffs between Charmouth and Lyme Regis in Dorset during the late 1850s. The original …

A layer of keratinous scutes encased the skull of Scelidosaurus. The neurocranium and the
associated principal sensory systems of this dinosaur are described. The cranial …

Resolving the evolutionary relationships of early diverging ('basal') ornithischian dinosaurs
is a challenging topic in palaeontology, with multiple competing hypotheses on the …

Functional analysis through computer modeling can inform on how extinct organisms moved
and fed, allowing us to test long-standing paleobiological hypotheses. Many such studies …
