A Brief Overview The Feathered Dinosaurs

• By Henry Winston Ball

The Arch-Type of the Birds

• In 1861, German paleontologists discovered in a
  lake bed the remains of an animal that was a
  fossilized remains of a dinosaur with feathers.
• Archaeopteryx or Urvogel the Original Bird was
  thought to be the first bird and from its
  descents the clan of birds started to take flight
  from this Jurassic fossil.

The Feathered Boom

• It was in the mid-1990s when a large discovery
  took place in the fossil remains of China.
  Feathered non-avian dinosaurs.
• And once more, these feathered dinosaurs belong
  all in the same group of theropod dinosaurs known
  as Coelurosauria, which include groups of animals
  such as raptors, therizinosaurs, tyrannosaurs,
  and eventually true birds.

Evidence of Flight

• With feathers, it was believed that they evolved
  as modified scales as most things evolve on
  animals, for sexual mating.
• Over time though, some animals-such as a personal
  favorite, Microraptor, could glide. And once
  more, it was a four-winged dinosaur that lived in
  the trees and took to the wing around the ancient
  Cretaceous forests.

The Color of the feathers

• In one interesting specimen of a feathered
  dinosaur, the clues to color is present.
  Paleontologists believe that the color of the
  dinosaur is evident do to the discovery of well
  preserved microscopic cell structures.
• With this evidence, the dinosaur known as
  Sinornithosaurus maybe the only dinosaur that we
  know its colors.
