Pigment or Bacteria? Researchers Re-examine the Idea of ‘Color’ in Fossil Feathers

Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research from North Carolina State University demonstrates that it is not yet possible to tell if these structures – thought to be melanosomes – are what they seem, or…

Iron Preserves, Hides Ancient Tissues in Fossilized Remains

New research from North Carolina State University shows that iron may play a role in preserving ancient tissues within dinosaur fossils, but also may hide them from detection. The finding could open the door to the recovery of more ancient tissues from within fossils. Mary Schweitzer, an NC State paleontologist with a joint appointment at the…
