Life in Earth's primordial sea was starved for sulfate
Vancouver, Canada (SPX) Nov 11, 2014
The Earth's ancient oceans held much lower concentrations of sulfate-a key biological nutrient-than previously recognized, according to research published this week in Science. The findings paint a new portrait of our planet's early biosphere and primitive marine life. Organisms require sulfur as a nutrient, and it plays a central role in regulating atmospheric chemistry and global climate. "Our findings are a fraction of previous estimates, and thousands of time lower than current seawater ... read more

Fossils force scientists to rethink 'unusual horrible hand' dino
It's a duck. It's a camel. It's an ostrich. No, it's Deinocheirus mirificus, the duck-camel-ostrich dino. Deinocheirus mirificus translates as "unusual horrible hands." But it's not just the hands of D. mirificus that are strange, its whole body is an odd hodgepodge of awkward features - the nose of a duckbill, the sail-like hump of a camel, the outstretched neck of an ostrich, not to mention the long arms and human-like hands. ... more

Tooth lodged in thighbone evidence of ancient dino struggle
Paleontologists have long assumed that semiaquatic dinosaurs and land-based predators mostly kept their distance from each other, preferring to avoid conflict or interaction of any sort. But a new discovery by researchers at the University of Tennessee and Virginia Tech - a tooth lodged in an ancient dino thighbone - suggests these predators may have faced off regularly. ... more
