Plenty of dinosaurs yet to be found

Despite a dramatic surge in dinosaur discoveries in recent years, paleontologists won't soon run out of interesting new fossils to unearth, a new analysis suggests.

. . . and the big bird that didn’t

The California condor, one of today's largest and rarest birds, may have survived the last ice age because of its varied diet.

The big fish that went away . . .

Fossils found near Charleston, S.C., suggest that an extinct species of billfish related to today's swordfish and marlin would easily exceed the lengths documented for world-record specimens of those oft-sought sports fish.

Dino Dwarf: Island living may have led to ancient downsizing

Fossils unearthed at a German quarry hint that members of one species of dinosaur that lived in the region about 152 million years ago evolved to be abnormally small because of the constraints of its island ecosystem.

Irish elk survived after ice age ended

New fossil finds indicate that the so-called Irish elk, previously thought to have died out at the end of the last ice age, survived in some spots for several millennia more.

Early Bird: Fossil features hint at go-get-’em hatchlings

A well-preserved, 121-million-year-old fossilized bird embryo has several features that suggest that the species' young could move about and feed themselves very soon after they hatched.

Big Gulp? Neck ribs may have given aquatic beast unique feeding style

The fossilized neck bones of a 230-million-year-old sea creature have features suggesting that the animal's snakelike throat could flare open and create suction to pull in prey.

Growth Spurt: Teenage tyrannosaurs packed on the pounds

Detailed analyses of tyrannosaur fossils suggest that the creatures experienced an extended growth spurt during adolescence.

Bird Brain? Cranial scan of fossil hints at flight capability

Detailed computerized tomography scans of the fossilized braincase of an Archaeopteryx show that several flight-related regions of the feathered creature's brain were highly developed.

Paleontology

Early life forms had a modular structure

Fossils recently discovered in northeastern Newfoundland reveal that some of Earth's earliest large organisms had modular body plans whose main architectural element was a branching, frondlike structure.

Paleontology

Chipmunks in Wisconsin toughed out ice age

Analyses of DNA from chipmunks in parts of the U.S. Midwest hint that some populations of the creatures stayed in northern refuges rather than migrating south at the beginning of the last ice age.

Neck Bones on the Menu: Fossil vertebrae show species interaction

Three fossil neck bones from an ancient flying reptile—one of them with the broken tip of a tooth embedded in it—indicate that the winged creatures occasionally fell victim to meat eaters.
