Autor: Rubén D F Martínez, Matthew C Lamanna, Fernando E Novas, Ryan C Ridgely, Gabriel A Casal, Javier E Martínez, Javier R Vita, Lawrence M Witmer

Publikováno v: PLoS ONE, Vol 11, Iss 4, p e0151661 (2016)

We describe Sarmientosaurus musacchioi gen. et sp. nov., a titanosaurian sauropod dinosaur from the Upper Cretaceous (Cenomanian-Turonian) Lower Member of the Bajo Barreal Formation of southern Chubut Province in central Patagonia, Argentina. The hol

A New Titanosaurian Braincase from the Cretaceous 'Lo Hueco' Locality in Spain Sheds Light on Neuroanatomical Evolution within Titanosauria.

Autor: Fabien Knoll, Lawrence M Witmer, Ryan C Ridgely, Francisco Ortega, Jose Luis Sanz

Publikováno v: PLoS ONE, Vol 10, Iss 10, p e0138233 (2015)

Despite continuous improvements, our knowledge of the neurocranial anatomy of sauropod dinosaurs as a whole is still poor, which is especially true for titanosaurians even though their postcranial remains are common in many Upper Cretaceous sites wor

Neurocranial osteology and neuroanatomy of a late Cretaceous titanosaurian sauropod from Spain (Ampelosaurus sp.).

Autor: Fabien Knoll, Ryan C Ridgely, Francisco Ortega, Jose Luis Sanz, Lawrence M Witmer

Publikováno v: PLoS ONE, Vol 8, Iss 1, p e54991 (2013)

Titanosaurians were a flourishing group of sauropod dinosaurs during Cretaceous times. Fossils of titanosaurians have been found on all continents and their remains are abundant in a number of Late Cretaceous sites. Nonetheless, the cranial anatomy o

The braincase of the basal sauropod dinosaur Spinophorosaurus and 3D reconstructions of the cranial endocast and inner ear.

Autor: Fabien Knoll, Lawrence M Witmer, Francisco Ortega, Ryan C Ridgely, Daniela Schwarz-Wings

Publikováno v: PLoS ONE, Vol 7, Iss 1, p e30060 (2012)

BackgroundSauropod dinosaurs were the largest animals ever to walk on land, and, as a result, the evolution of their remarkable adaptations has been of great interest. The braincase is of particular interest because it houses the brain and inner ear.

Cartilaginous epiphyses in extant archosaurs and their implications for reconstructing limb function in dinosaurs.

Autor: Casey M Holliday, Ryan C Ridgely, Jayc C Sedlmayr, Lawrence M Witmer

Publikováno v: PLoS ONE, Vol 5, Iss 9, p e13120 (2010)

Extinct archosaurs, including many non-avian dinosaurs, exhibit relatively simply shaped condylar regions in their appendicular bones, suggesting potentially large amounts of unpreserved epiphyseal (articular) cartilage. This "lost anatomy" is often

Two exceptionally preserved juvenile specimens of Gorgosaurus libratus (Tyrannosauridae, Albertosaurinae) provide new insight into the timing of ontogenetic changes in tyrannosaurids

Autor: Jared T. Voris, Darla K. Zelenitsky, François Therrien, Ryan C. Ridgely, Philip J. Currie, Lawrence M. Witmer

Known from dozens of specimens discovered since the early 20th century, Gorgosaurus libratus has arguably contributed more than any other taxon to our understanding of the life history of tyrannosaurids. However, juvenile material for this taxon is r

In the present contribution we revise, figure, and redescribe several isolated braincases of the iconic aetosaur Desmatosuchus from the Placerias Quarry locality, Chinle Formation, Arizona, USA. The detailed study of the isolated braincases from the

Beyond Endocasts: Using Predicted Brain-Structure Volumes of Extinct Birds to Assess Neuroanatomical and Behavioral Inferences

Autor: Catherine M. Early, Ryan C. Ridgely, Lawrence M. Witmer

Publikováno v: Diversity
Volume 12
Issue 1
Diversity, Vol 12, Iss 1, p 34 (2020)

The shape of the brain influences skull morphology in birds, and both traits are driven by phylogenetic and functional constraints. Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D-pre
