Forearm orientation in Hadrosauridae (Dinosauria: Ornithopoda) and implications for museum mounts [PDF]

open access: yesPalaeontologia Electronica, 2012
Skeletons of hadrosaurids (“duck-billed dinosaurs”) are usually mounted with palms facing caudally (posteriorly). To achieve this, the radius is articulated with the medial (ulnar) condyle of the humerus instead of the lateral (radial) condyle, which would be unique among vertebrates if it were correct.

Allozyme variation in Carex sect. Digitatae - Evidence of introgression, genetic distinctiveness and evolution of taxa

open access: yes, 2003
A subset of populations of the European taxa of Carex sect. Digitatae, including Carex digitata, C. pallens, C. ornithopoda, C. pediformis ssp. rhizodes and C. humilis have been investigated for allozyme variation.

An upgraded key for identifying all native species, subspecies and varieties of the genus Carex (Cyperaceae) in Europe and the Caucasus

open access: yesNordic Journal of Botany, Volume 2025, Issue 8, August 2025.
The last pan‐European key to Carex taxa was published in 1980 by Chater. Since that time several new species have been described, and numerous nomenclatural changes, including the recognition that the former genus Kobresia should be incorporated into Carex as C. subg. Euthyceras, have been made. This article provides a comprehensive key to identify all

The origins of neural spine elongation in iguanodontian dinosaurs and the osteology of a new sail‐back styracosternan (Dinosauria, Ornithischia) from the Lower Cretaceous Wealden Group of England

open access: yesPapers in Palaeontology, Volume 11, Issue 4, July/August 2025.
Abstract The Wealden Group of southern England was deposited during the late Berriasian to early Aptian interval. It records a critical time in the development of iguanodontian dinosaur diversity, which increased from low levels during the Jurassic to higher levels in the Aptian and Albian. A new iguanodontian dinosaur, Istiorachis macarthurae gen.

How femoral morphology informs our understanding of the evolution of ornithopod locomotion and body size

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Ornithopoda is one of the three main ornithischian dinosaur clades in which secondary quadrupedality is represented. However, when it evolved from obligate bipedality remains controversial. Indeed, the ability to alternate between the two habits was inferred in some ornithopods based on ichnological observations and a mosaic of bipedal and ...
