An international team of scientists used synchrotron radiation to image and analyze fossilized fish from the Tanis deposit in North Dakota. Some 66 million years ago, a catastrophic event wiped out three-quarters of all plant and animal species on Earth, most notably taking down the dinosaurs. The puzzle of why so many species perished while […]

Trapped in amber: Fossilized dinosaur-era crab bridges evolutionary gap
Enlarge Once upon a time, during the Cretaceous period, a tiny crab wandered out of the water onto land and somehow got trapped in amber, which preserved it for 100 million years. At least that’s what a team of scientists hypothesize might have happened in a new paper announcing their discovery of the oldest known […]
Astronomers: A comet fragment, not an asteroid, killed off the dinosaurs

Some 66 million years ago, a catastrophic event occurred that wiped out three-quarters of all plant and animal species on Earth, most notably taking down the dinosaurs. An errant asteroid from the asteroid belt has been […]
