Throughout the year we highlight research images that are worth a thousand words. For this year-end list, we’d like to extend the category to our research videos. Here, we’ve highlighted some of this year’s most popular videos, published in the Supporting … Continue reading
The post Sharing is Caring: Varied Diets in Dinosaurs Promoted Coexistence appeared first on EveryONE.
The exceptional gigantism of sauropod dinosaurs has long been recognized as an important stage in the evolution of vertebrates, the presence of which raises questions as to why no other land-based lineage has ever reached this size, how these dinosaurs functioned as living animals, and how they were able to maintain stable populations over distinct geological periods.
We are pleased to announce the publication of a PLOS Collection featuring new research on the complex Evolutionary Cascade Theory that attempts to answer these questions and explain how the unique gigantism of sauropod dinosaurs was possible. The fourteen papers that make up the collection address sauropod gigantism from a number of varied disciplinary viewpoints, including ecology, engineering, functional morphology, animal nutrition, evolutionary biology, and paleontology.
Sauropod dinosaurs were the largest terrestrial animals to roam the earth, exceeding all other land-dwelling vertebrates in both mean and maximal body size. While convergently evolving many features seen in large terrestrial mammals, such as upright, columnar limbs and barrel-shaped trunks, sauropods evolved some unique features, such as the extremely long necks and diminutive heads they are famous for. Dr Martin Sander, Professor of Paleontology at Universität Bonn and coordinating author for this series of 14 papers, said of the collection:
“This new collection brings together the latest research on the biology of sauropod dinosaurs, the largest animals to ever walk on Earth. Having been extinct for 65 million years, reconstructing sauropod biology represents a particular challenge. Using a wide array of scientific expertise, often from seemingly unlikely fields, has led to some amazing insights. For example, principles of soil mechanics have been used to ‘weigh a dinosaur’ based on its trackways, whilst the latest in computer modeling can make a dinosaur walk again.
The ultimate question underlying this research is how sauropods were able to evolve their uniquely gigantic body size. The wide-ranging disciplines covered in the collection means that there is a -broad, multi-disciplinary audience for the research, as well as general interest in dinosaurs; therefore, we felt that it was essential to publish such a volume in a leading open-access journal such as PLOS ONE to ensure the widest possible dissemination of our work.”
Readers are able to download “Sauropod Gigantism: A Cross-Disciplinary Approach” not only as a PDF but also as an ebook (.mobi and .epub formats) from the collection page. It will also be available on Flipboard (search “PLOS Collections”).
