Data from: Mosaicism in a new Eocene pufferfish highlights rapid morphological innovation near the origin of crown tetraodontiforms

Roger A. Close, Zerina Johanson, James C. Tyler, Richard C. Harrington & Matt Friedman
Tetraodontiformes (pufferfishes and kin) is a taxonomically and structurally diverse, widely-distributed clade of acanthomorphs, whose members often serve as models for genomics and, increasingly, macroevolutionary studies. Morphologically disparate Palaeogene fossils suggest considerable early experimentation, but these flattened specimens often preserve limited information. We present a three-dimensionally preserved beaked tetraodontiform from the early Eocene (c. 53 Ma) London Clay Formation, UK. Approximately coeval with the oldest crown tetraodontiforms, †Ctenoplectus williamsi gen. et sp. nov. presents an...

Data from: Rates and processes of aeolian soil erosion in West Greenland

Ruth C. Heindel, Lauren E. Culler & Ross A. Virginia
In arid landscapes across the globe, aeolian processes are key drivers of landscape change, but arid Arctic regions are often overlooked. In the Kangerlussuaq region of West Greenland, strong katabatic winds have removed discrete patches of soil and vegetation, exposing unproductive glacial till and bedrock. Although lake-sediment records suggest that landscape destabilization began approximately 1000 years ago, the upland soil erosion has never been directly dated. We use a novel application of lichenometry to estimate...

Data from: A new western European Cretaceous bryozoan genus from the early Cenomanian radiation of neocheilostomes

Silviu O. Martha & Paul D. Taylor
Neocheilostomes possessing ovicells for larval brooding originated in the late Albian and radiated explosively in the Late Cretaceous. Our understanding of this radiation is hampered by poor knowledge of the taxonomy of the earliest neocheilostomes. Here we describe a new neocheilostome genus, Ehrhardina, from shallow-water sediments in the early Cenomanian of Western Europe. Two species (Ehrhardina voigti sp. nov. and E. pikeae sp. nov.) are referred to the new genus. Ehrhardina gen. nov. is an...

Data from: Two new species of Ichthyosaurus from the lowermost Jurassic (Hettangian) of Somerset, England

Dean R. Lomax & Judy A. Massare
All specimens of Ichthyosaurus from the Lower Jurassic of Somerset were previously identified as I. communis, an abundant and extremely variable species. Here, two new species of Ichthyosaurus are recognized from multiple specimens. The species are assigned to Ichthyosaurus on the basis of the humerus, pectoral girdle and forefin morphologies. I. larkini sp. nov. is distinguished by a broad jugal with a blunt anterior end that extends as far forward as the middle of the...

Data from: Comparative cranial myology and biomechanics of Plateosaurus and Camarasaurus and evolution of the sauropod feeding apparatus

David J. Button, Paul M. Barrett & Emily J. Rayfield
Sauropodomorpha represents an important group of Mesozoic megaherbivores, and includes the largest terrestrial animals ever known. It was the first dinosaur group to become abundant and widespread, and its members formed a significant component of terrestrial ecosystems from the Late Triassic until the end of the Cretaceous. Both of these factors have been explained by their adoption of herbivory, but understanding the evolution of sauropodomorph feeding has been hampered by the scarcity of biomechanical studies....
