Big pimpin' in the late Cretaceous

Man, Kanye has nothing on these guys. Scientists have revealed that agglutinated foraminifera, tiny one-celled organism, can't get enough ice. Diamonds, that is. And alien diamonds at that.

Fossil records show that the foraminifera used tiny diamond particles, created by the giant meteor impact that killed the dinosaurs, as a protective coating.  Said the New Scientist:

It seems the main reason the foraminifera chose grains containing diamonds and metals for their tests was the lack of other grains of a similar density at this particular site. What remains a mystery is how these ancient foraminifera were able to pick out the densest grains, an ability they share with their latter-day descendants.

Or maybe, just maybe,  they liked to do it up big style.
