Intraskeletal histovariability and skeletochronology in an ornithopod dinosaur from the Maestrazgo Basin (Teruel, Spain)

open access: yesJournal of Anatomy, Volume 247, Issue 3-4, Page 643-664, September/October 2025.
Abstract Ornithopods are an extinct group of dinosaurs that were particularly abundant and diverse in the Cretaceous of the Iberian Peninsula, and whose abundance in the Maestrazgo Basin has allowed numerous taxa to be identified over the last decade. Many of these fossil remains are still taxonomically indeterminate and require a more detailed study ...

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 ...
