    ‘End of the Megafauna’ examines why so many giant Ice Age animals went extinct

    End of the MegafaunaRoss D.E. MacPhee and Peter Schouten (illustrator)W.W. Norton & Co., $35

    Today’s land animals are a bunch of runts compared with creatures from the not-too-distant past. Beasts as big as elephants, gorillas and bears were once much more common around the world. Then, seemingly suddenly, hundreds of big species, including the woolly mammoth, the giant ground...

    Eggs evolved color and speckles only once — during the age of dinosaurs

    The colorful, speckled eggs of modern birds are an innovation inherited from their nonavian dinosaur ancestors.

    A new analysis of the pigmentation in modern and fossilized eggshells suggests that eggs evolved to be colorful only once — in modern birds’ dinosaur ancestors, a team of vertebrate paleontologists report online October 31 in Nature. Color patterns found in the eggshells of...

    The first vertebrates on Earth arose in shallow coastal waters

    The cradle of vertebrate evolution was limited to a zone of shallow coastal waters, no more than 60 meters deep.

    In those waters, fish — the first vertebrates — appeared roughly 480 million years ago, a study finds. For nearly 100 million years, those creatures rarely strayed from that habitat, where they diversified into a dizzying array of new forms, scientists report in the Oct. 26...

    T. rex pulverized bones with an incredible amount of force

    ALBUQUERQUE — Tyrannosaurus rex had a special way of crunching bones.

    A lethal combination of a powerful bite, strong teeth and repeated crunching allowed these giant predators to pulverize the bones of their prey, researchers reported October 20 at the Society for Vertebrate Paleontology’s annual meeting.

    Bones have a nutritious inner cavity containing marrow and phosphate salts....

    In a first, scientists spot what may be lungs in an ancient bird fossil

    ALBUQUERQUE — Fossilized lungs found preserved along with an ancient bird may breathe new life into studies of early avian respiration. If confirmed as lungs, the find marks the first time that researchers have spotted the respiratory organs in a bird fossil.

    Scientists have previously described four fossils of Archaeorhynchus spathula, an early beaked and feathered bird that lived about...
