Rocks yield clues to flower origins

A distinctive organic chemical related to substances produced by modern flowering plants has been found in ancient fossil-bearing sediments, possibly helping to identify the ancestral plants that gave rise to flowers.

Fake fossil not one but two new species

A supposed missing link between dinosaurs and birds that was first unveiled in 1999, and revealed to be a forgery soon thereafter, was actually cobbled together from parts of animals from two new species.

Jumbled bones show birds on the menu

A fossilized pellet of partially digested bones of juvenile and baby birds provides the first evidence that birds served as food for predators.

First brachiosaur tooth found in Asia

A fossil tooth found along a dinosaur trackway in South Korea is the first evidence that brachiosaurs roamed Asia.

Dinosaur fossil yields feathery structures

Researchers believe they have found primitive feathers on the remains of Sinornithosaurus millenii, a 124-million-year-old raptor dinosaur from Liaoning, China.

Extinctions Tied to Impact from Space

Evidence trapped in 250-million-year-old sediments may help researchers pin the ultimate blame for the massive extinctions that occurred then on the impact of an extraterrestrial object about 9 kilometers across.

Did ancient superbees squash diversity?

The recent discovery of several dozen extinct bee species in ancient amber deposits has led one paleontologist to propose that the very success of some bees' social lifestyle led to today's dearth of hive-dwelling species.

Genes Seem to Link Unlikely Relatives

Genetic markers on three proteins suggest a common African ancestor for elephants, aardvarks, elephant shrews, golden moles, and other animals.
