    Ticks had a taste for dinosaur blood

    Ticks once tickled dinosaurs’ feathers.

    The tiny arthropods have been surreptitiously sucking blood for more than 100 million years, but evidence of early ticks’ preferred hosts has been scant. Now, samples of amber from Myanmar have caught the critters with their spiny mouthparts inside the cookie jar. A hunk of 99-million-year-old amber holds a tick tangled in a dinosaur feather,...

    This ancient marsupial lion had an early version of ‘bolt-cutter’ teeth

    A skull and other fossils from northeastern Australia belong to a new species in the extinct family of marsupial lions.

    This newly named species, Wakaleo schouteni, was a predator about the size of a border collie, says vertebrate paleontologist Anna Gillespie of the University of New South Wales in Sydney. At least 18 million years ago (and perhaps as early as 23 million years ago), it...

    This new dinosaur species was one odd duck

    It may have walked like a duck and swum like a penguin, but a flipper-limbed creature discovered in what is now Mongolia was no bird. The strange new species is the first known nonavian dinosaur that could both run and swim, researchers say.

    To compensate for a long swanlike neck, probably used for dipping underwater for fish, this dino’s center of mass shifted toward its hips, allowing...

    Jackpot of fossilized pterosaur eggs unearthed in China

    Hundreds of eggs belonging to a species of flying reptile that lived alongside dinosaurs are giving scientists a peek into the earliest development of the animals.

    The find includes at least 16 partial embryos, several still preserved in 3-D. Those embryos suggest that the animals were able to walk, but not fly, soon after hatching, researchers report in the Dec. 1 Science.

    Led by...

    Here’s yet more evidence that the mythical yeti was probably a bear

    Campfire legends of massive, shaggy bipeds called yetis are grounded in a less mysterious truth: bears.

    Eight samples of remains such as fur, bones and teeth purportedly from mountain-dwelling yetis actually come from three different kinds of bears that live in the Himalayas, researchers report November 29 in the Proceedings of the Royal Society B. A ninth sample turned out to come from...

    What male bias in the mammoth fossil record says about the animal’s social groups

    Male mammoths really had to watch their steps. More than two-thirds of woolly mammoth specimens recovered from several types of natural traps in Siberia came from males, researchers report November 2 in Current Biology.

    Paleogenomicist Patrícia Pečnerová of the Swedish Museum of Natural History in Stockholm and her colleagues examined genomic data recovered from 98 mammoth bone, tooth,...

    New dinosaur sported a curious set of chompers

    An ancient vegetarian dinosaur from the French countryside has given paleontologists something to sink their teeth into.

    The most striking feature of a new species of rhabdodontid that lived from 84 million to 72 million years ago is its oversized, scissorslike teeth, paleontologist Pascal Godefroit, of the Royal Belgian Institute of Natural Sciences in Brussels, and his colleagues...

    T. rex’s silly-looking arms were built for slashing

    SEATTLE — Tyrannosaurus rex may have had small arms, but it was no pushover.

    This fierce dinosaur is known for its giant head, powerful jaws and overall fearsome appearance — except for those comical-looking arms. But the roughly meter-long limbs weren’t just vestigial reminders of a longer-armed past, paleontologist Steven Stanley of the University of Hawaii at Manoa said October 23 at...

    Ancient whale turns up on wrong side of the world

    A new discovery is turning the hemispheric history of a mysterious whale species upside-down. Two fossils recently unearthed in Italy and Japan suggest that a southern whale was briefly a denizen of northern waters more than half a million years ago.

    Until now, all available evidence suggested that the pygmy right whale, Caperea marginata, and its ancestors have been steadfast Southern...

    A baby ichthyosaur’s last meal revealed

    As far as last meals go, squid isn’t a bad choice. Cephalopod remains appear to dominate the stomach contents of a newly analyzed ichthyosaur fossil from nearly 200 million years ago.

    The ancient marine reptiles once roamed Jurassic seas and commonly pop up in England’s fossil-rich coast near Lyme Regis. But a lot of ichthyosaur museum specimens lack records of where they came from,...
