This congruence between the full range of paleontological and developmental data strongly supports the hypothesis that feathers evolved[or were created for diversification as Intelligent Design would maintain, MrB.] and initially diversified in nonavian theropods before the origin of birds and the evolution of flight." From the abstract for the article, "A New Feather Type in a Nonavian Theropod and the Early Evolution of Feathers by Xing Xu, Xiaoting Zheng and Hailu You in the Proceedings of the National Academy of Sciences.

A fossil of a primitive feathered dinosaur uncovered in <a href="http://travel.nationalgeographic.com/places/countries/country_china.html">China</a> is helping scientists create a better model of how dinosaurs evolved into modern birds.
The winged dinosaur is still in the process of being dated, and might have lived toward the end of the Jurassic period, which lasted from 208 to 144 million years ago.<!--- deckend --->

Four, Three, Two, One . . . Pterosaurs Have Lift Off
Science Daily (press release) - Jan 6, 2009
Even paleontologists assumed that because the creatures flew, they were birdlike in many ways, such as using only two legs to take flight. ...

The skull's size suggests that the Brazilian pterosaur had a roughly 16-foot (5-meter) wingspan and stood about 3.3 feet (a meter) high at its shoulders. With its long neck and jaw, the animal would have seemed as tall as a typical adult human (right).

I went back a few days, to find my copy of the AP report of Habib's findings. From a telephone interview, they quote him with concurrence from David Unwin of the University of Leicester that these reptile "birds" are not best to be thought of as your ordinary avian species! "Last year, researchers tried to figure out how they[in addition to the Hatzegopteryx (next to the giraffe in the "photo" link above) at 40 feet or more wingspan is an illustration of the 30 foot toothless pteranodon in flight] got off the ground by looking at the largest bird now flying, the albatross. They concluded that anything much bigger couldn't get off the ground the same way." Much to learn, it seems as new creature's fossils are found in rapid succession. And I am a bit confused: the AP illustration(provided by The Johns Hopkins University) calls it one thing(H. thambema) and the National Geographic calls it "
Lacusovagus magnificens, or "magnificent lake wanderer," is the largest of its kind yet found, a new study reports." ?
