archaeopteryx  (ärk-ptr-ks)
An extinct primitive bird of the genus Archaeopteryx of the Jurassic Period, having characteristics of both birds and dinosaurs.

The new dinosaur may look bird-like because of its size, but in fact it isn't very closely related to birds or Archaeopteryx (the world's first known bird)," said Chiappe, who is director of the Natural History Museum's Dinosaur Institute in Los Angeles.
The creature, which stood about 28 centimeters tall at the hip, is the oldest known to have sported feathers and is estimated to be between 1 million and 11 million years older than Archaeopteryx, the first known bird.
The finds were unearthed from rocks dated at around 160 million years ago, which places them close to the boundary line between the Middle and Late Jurassic periods, and at least 10 million years older than the first recognised bird, Archaeopteryx.
