      Tyrannosaurus Rex: Tastes Like Chicken?

      (Newser) - Dinosaurs are more closely related to birds than reptiles, protein extracted from a Tyrannosaurus rex bone suggests. T. rex collagen, the main protein in bones, is similar to chicken and ostrich collagen but much different than material from alligators and lizards, scientists say. The findings could remap the evolutionary tree according to molecular data rather than bone structure, the Washington Post reports. More »

    • Did Bug Bites Do in Dinos?

      Did Bug Bites Do in Dinos?

      (Newser) - Disease-carrying insects may have contributed to the extinction of the dinosaurs around 65 million years ago, entomologists write in a new book. Scientists found malaria and other parasitic pathogens in insects preserved in amber, and the same parasites were found in fossilized dinosaur waste, the Guardian reports. New plants, pollinated by insects, forced the herbivores to adapt their diets or starve, the book also suggests. More »

      'Mummified' Dinosaur Body Unearthed

      (Newser) - A remarkably well-preserved hadrosaur discovered in North Dakota offers valuable clues about the appearance of dinosaurs, paleontologists say. Soft tissue such as skin and muscle were effectively "mummified" after the dinosaur died near a river, the Washington Post reports. "It's a dinosaur that was turned into stone, essentially," says the grad student who discovered it when he was in high school. More »

      Long-Necked Dinosaur Grazed Like a Cow

      (Newser) - The long-necked plant-eating dinosaur Nigersaurus ate its meals off the ground rather than reaching into trees, National Geographic reports. Fossils of the 30-foot-long creature reveal that the animal probably nibbled on plants such as ferns and horsetails. “We have seen nothing like this dinosaur,” said a paleontologist at the University of Chicago.

    • Volcanoes Helped Doom Dinos

      Volcanoes Helped Doom Dinos

      (Newser) - Not one but two catastrophic events may have spelled destruction for the Age of Dinosaurs, previously thought to have ended when an asteroid or comet struck the earth. New research suggests the prehistoric giants died off in “an unfortunate coincidence of a one-two punch—of Deccan volcanism and then a hit from space," said a Princeton paleontologist. More »

      Raptors Really Ran in Packs —in China

      (Newser) - The dinos depicted in Jurassic Park really were big and nasty and hunted in packs, and fossilized footprints show where they did it: in China, about 100 millions ago. Standing 1.2 meters tall at the hip, the dromeosaurs ran in packs of six and held up big killing claws—just like in the movie. They weighed about 200 pounds, experts say, like a big cougar or jaguar.

      Big Bird Dazzles Paleontologists

      (Newser) - The largest birdlike creature on record stood over 16 feet tall, weighed a ton and a half, and had sharp claws but no teeth. The Chinese paleontologist who unearthed the creature's thigh bone wasn't sure what it was, he tells the San Francisco Chronicle, but as he listed the possibilities for a colleague he realized: "We have a gigantic chicken!"
