Rethinking early atmospheric oxygen: Possibility of more dynamic biological oxygen cycle on early Earth than previously supposed
http://feeds.sciencedaily.com —
Using a quantitative model, a research team of biogeochemists has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth's history, and its relationship to the sulfur cycle. Their model, the researchers argue, is one step toward a more integrated view of how Earth's crust, mantle and atmosphere i

Early prehistoric marine reptiles: Evidence of a placodont that originated in Europe
http://feeds.sciencedaily.com —
Placodonts were among the first marine reptiles. With their trademark crushing teeth, they fed on shellfish and crustaceans. However, when and where these highly specialized marine reptiles originated remained unclear until now. A 246-million-year-old skull of a juvenile placodont was recently discovered in the Netherlands. Paleontologists have now demonstrated that it is one of the earliest exam

Oxygen-poor 'boring' ocean challenged evolution of early life
http://feeds.sciencedaily.com —
Biogeochemists have filled in a billion-year gap in our understanding of conditions in the early ocean during a critical time in life's history on Earth. During the period 1.8 to 0.8 billion years ago, oxygen likely remained low in the atmosphere and ocean, with marine life dominated by bacteria. The ocean was oxygen-free and iron-rich in the deepest waters and hydrogen sulfide-containing over li

Bat disease: More accurate, sensitive DNA test allows early identification of fungus causing white nose syndrome
http://feeds.sciencedaily.com —
Scientists are identifying additional species of Geomyces and describing development of a highly sensitive DNA-based technique for early identification of Geomyces destructans on bats as well as in soils and on cave walls.
