    With dinosaurs out of the way, mammals had a chance to thrive

    For dinosaurs, the end of the world began in fire.

    The space rock that stamped a Vermont-sized crater into the Earth 66 million years ago packed a powerful punch. Any animal living within about a thousand miles of the impact zone was probably vaporized, says paleontologist Stephen Brusatte of the University of Edinburgh in Scotland.

    “Everything would have been toast.”

    All Rachel Racicot wanted to do was look at a fossil. As a paleontology graduate student at San Diego State University, Racicot had scheduled some time with a local hospital’s CT scanner. She was going to examine a 3-million-year-old porpoise jaw.

    But when the day came to slide the fossil into the scanner, the hospital put her on hold. A...

    Flexible molars made chewing champions out of duck-billed dinosaurs

    Duck-billed dinosaurs may have been the sheep of their ecosystems, instead of the deer.

    Patterns of tiny scratches in the fossilized teeth of Edmontosaurus, a type of hadrosaur, suggest the dinos had more complex jaw movements than previously thought, and may have eaten grass-like plants instead of trees, researchers report online June 29 in the Proceedings of the National...

    Newfound dinosaur wasn't sticking its neck out

    Sauropod dinosaurs, the group of herbivores that included the largest land animals that ever lived, are renowned for their incredibly long necks. Fossils of a newly discovered, 10-meter-long species excavated in South America, however, suggest that this particular sauropod bucked that trend.

    Many scientists consider the long necks of most sauropods to be an important feeding adaptation...

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

    A fossilized bird embryo dating to 121 million years ago has features that suggest that the species' young, unlike those of many modern birds, could walk about and feed themselves right after they hatched.

    The specimen, tucked in an oval shape about 35 millimeters long, was extracted from a layer of shale in northeastern China. Although the relic doesn't include any...

    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 that would pull in prey. Such a feeding strategy has never before been proposed for an ancient aquatic reptile.

    Paleontologists working in southern China recently unearthed the partial remains of Dinocephalosaurus...

    Allosaurus as a Jurassic headbanger

    From Mexico City, at the 60th annual meeting of the Society of Vertebrate Paleontology

    Being referred to as thickheaded isn't exactly a compliment. Depending on your lifestyle, however, you just might need a skull that can occasionally take a good smack.

    Consider a carnivorous dinosaur such as Allosaurus fragilis attacking and feeding on its prey. New research shows that the...

    L.A.'s Oldest Tourist Trap

    Cruise Los Angeles' Wilshire Boulevard and, when you reach the 5800 block, you'll often catch a whiff of fresh tar. Most likely, it won't be coming from a road or roofing crew, but you'll have a big clue to its source. On the north side of the boulevard, there's a life-size fiberglass model of a terrified mammoth stuck hip-deep in goo. The figure marks one of the world's most well-known...

    Learning from the Present

    Several meters away, through the wavering heat of a desert afternoon, a paleontologist spies what looks like a thumb-size chip of bone. As he approaches the relic, he wonders what it will be: A piece of leg bone? A fragment of skull? A chunk of a vertebra? What sort of creature does this remnant represent? The paleontologist reaches the find, kneels, and whips out a whisk broom. Delicately,...
