The early origin of Iguanodontia: new insights into the macroevolution, diversity and biogeography of the clade

open access: yesPalaeontology, Volume 69, Issue 2, 2026.
Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.

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

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.

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.
