Diamonds are sometimes described as messengers from the deep earth; scientists study them closely for insights into the otherwise inaccessible depths from which they come. But the messages are often hard to read. Now, a team has come up with a way to solve two longstanding puzzles: the ages of individual fluid-bearing diamonds, and the chemistry of their parent material. The research has allowed them to sketch out geologic events going back more than a billion years a potential breakthrough not only in the study of diamonds, but of planetary evolution.

A new paper refines estimates of when herbivorous dinosaurs must have traversed North America on a northerly trek to reach Greenland, and points out an intriguing climatic phenomenon that may have helped them along the journey.
The study, published today in
Proceedings of the National Academy of Sciences, is authored by Dennis Kent, adjunct research scientist at Columbia University s Lamont-Doherty Earth Observatory, and Lars Clemmensen from the University of Copenhagen.
