  • found evidence that dinosaurs probably had a high metabolic rate to allow fast growth -- another indicator of warm-bloodedness
  • cold-blooded, meaning they cannot control their body temperatures through their own metabolic system
  • bones of warm-blooded animals such as birds and mammals had never been properly assessed

  • Annual growth lines etched in the femurs of 115 wild warm-blooded mammals such as giraffes, reindeer and gazelles are similar to those previously seen in the bones of reptiles and dinosaurs
  • People always said that mammals do not show these lines
  • like a myth that’s going around; you read it everywhere
  • ...14 more annotations...
  • people haven’t really studied mammals
  • In dinosaurs and reptiles, yearly cycles of growth and nutrition are stamped in the bones like the rings of a tree
  • months, animals pack on blood vessel-rich bone tissue
  • lean months they skimp, laying down only thin sheets
  • Under a microscope, the slender sheets of bone look like dark lines
  • “lines of arrested growth” or “rest lines” stripe the bones of both dinosaurs and reptiles, some scientists assumed that dinosaurs, like reptiles, were cold-bloode
  • new work shows that warm-blooded mammals have banded bones, too
  • Every mammal Köhler’s team examined showed cyclical growth
  • their specimens looked just like those seen in dinosaur fossils.
  • probably not going to close the debate whether dinosaurs were warm-blooded or not
  • the argument that [rest lines] mean cold-blooded is certainly not valid any longer
  • analyzed bone slices — as thin as strands of human hair — from 41 species of ruminants — mammals with four-chambered stomachs
  • Institute of Zoology at the University of Hamburg donated most of the skeletal specimens from its Oboussier collection

"Beautiful" Squirrel-Tail Dinosaur Fossil Upends Feather Theory - 0 views

  • Previously, paleontologists have found feathers only on coelurosaurs—small, birdlike dinosaurs that evolved later than so-called megalosaurs suchas Sciurumimus.
  • the oldest known meat-eating dinosaur with feathers
  • hatchling had a large skull, short hind limbs, and long, hairlike plumage on its midsection, back, and tail.
  • ...1 more annotation...
  • Because Sciurumimus is from a completely different branch of the dinosaur family tree from the coelurosaurs, the new fossil suggests feathered dinosaurs were the norm, not the exception

All Dinosaurs May Have Had Feathers - Science News - 0 views

shared by Mars Base on 03 Jul 12 - No Cached
  • A newly discovered, nearly complete fossilized skeleton hints that all dinosaurs may have sported feathers.
  • Eventually, the study’s authors hope to figure out the color of the dinosaur’s feathers. But because color tests require fossil snippets, scientists would have to clip bits from the dinosaur’s remains. And since this specimen is one of a kind, researchers aren’t quite ready to disturb it.
  • So far, nearly all of the feathered dinosaurs ever discovered have come from eastern Asia. But excavators unearthed this fossil in southern Germany

  • If the Higgs is found, the question turns to whether its properties match predictions made by the standard model, or whether they are slightly different
  • How long it will take, though, remains a mystery. “I can tell you 2012 is the year” to learn if the Higgs exists or not, says Tom LeCompte of Argonne National Laboratory. “I can’t tell you July is the month.”

  • mostly composed of rock, the flexing would be in the neighborhood of around 3 feet (1 meter.)
  • measurements taken by the Cassini spacecraft, which has been orbiting Saturn since 2004, Titan exhibits much more intense flexing — ten times more, in fact, as much as 30 feet (10 meters

  • the presence of such an ocean — possibly containing trace amounts of ammonia – would help explain how methane gets replenished into the moon’s thick atmosphere.
