    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...

    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...

    Giant armored dinosaur may have cloaked itself in camouflage

    Sometimes body armor just isn’t enough. A car-sized dinosaur covered in bony plates may have sported camo, too, researchers report online August 3 in Current Biology. That could mean the Cretaceous-period herbivore was a target for predators that relied on sight more than smell to find prey.

    The dinosaur, dubbed Borealopelta markmitchelli, has already made headlines for being one of the...

    Under lasers, a feathered dino shows some skin

    What happens when you shoot lasers at a dinosaur fossil? Some chemicals preserved in the fossil glow, providing a nuanced portrait of the ancient creature’s bones, feathers and soft tissue such as skin.

    Soft tissue is rarely preserved in fossils, and when it is, it can be easily obscured. A technique called laser-stimulated fluorescence “excites the few skin atoms left in the matrix,...

    Bony head ornaments signal some supersized dinosaurs

    Dinosaur fashion, like that of humans, is subject to interpretation. Bony cranial crests, horns or bumps may have served to woo mates or help members of the same species identify one another. While the exact purpose of this skull decor is debated, the standout structures tended to come with an even more conspicuous trait: bigger bodies.

    Terry Gates, a paleontologist at North Carolina...

    Cretaceous bird find holds new color clue

    A 130-million-year-old bird holds a clue to ancient color that has never before been shown in a fossil.

    Eoconfuciusornis’ feathers contain not only microscopic pigment pods called melanosomes, but also evidence of beta-keratin, a protein in the stringy matrix that surrounds melanosomes, Mary Schweitzer and colleagues report November 21 in the Proceedings of the National Academy of...

    Averages can conceal how people and science learn

    Picture a learning curve. Most of us imagine a smooth upward slope that rises with steady mastery. It is the ultimate image of progress.

    But that image, as behavioral sciences writer Bruce Bower reports in "Kids learning curve not so smooth" (SN: 11/26/16, p. 6), may well be an illusion of statistics, created when people look at averages of a group instead of how individuals...

    Dinosaurs may have used color as camouflage

    The stories of dinosaurs’ lives may be written in fossilized pigments, but scientists are still wrangling over how to read them.

    In September, paleontologists deduced a dinosaur’s habitat from remnants of melanosomes, pigment structures in the skin. Psittacosaurus, a speckled dinosaur about the size of a golden retriever, had a camouflaging pattern that may have helped it hide in forests...

    Fossils, now available in color

    Researchers have found what appear to be remnants of pigment in fossilized feathers, opening the possibility of reconstructing the colors of many long-extinct animals.

    Dark stripes in a 100-million-year-old fossilized feather — coming from an early bird or a dinosaur — contain particles that closely resemble, in size and arrangement, black melanin particles...
