UCSB researcher leads worldwide study on marine fossil diversity
(Santa Barbara, Calif.) - It took a decade of painstaking study, the cooperation of hundreds of researchers, and a database of more than 200,000 fossil

New fossil tells twisted tale of how flatfishes ended up with two eyes on one side of head
CHICAGOA newly identified fossil

All living flatfishes, which include halibut, ...
Ocean acidification -- another undesired side effect of fossil fuel-burning
Up to now, the oceans have buffered climate change considerably by absorbing almost one third of the worldwide emitted carbon dioxide. The oceans represent a significant carbon sink, but the uptake of excess CO2 stemming from mans burning of fossil

First orchid fossil puts showy blooms at some 80 million years old
CAMBRIDGE, Mass. -- Biologists at Harvard University have identified the ancient fossilized remains of a pollen-bearing bee as the first hint of orchids in the fossil

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil
