There are "trousers"-like protrusions on the feathers of ancient creatures between dinosaurs and birds. Archaeopteryx feathers spread throughout the body, not just its wings. A newly discovered fossil confirmed this. The Archaeopteryx caused a great sensation when it was first unearthed in Germany in 1861, because two years ago Charles Darwin published The Origin of Species. It has dinosaur claws and teeth, but it has bird feathers. It is clearly a transitional species, and it clearly proves Darwin's theory.
The fossil specimen was announced in 2011 and is clearly intact, with feathers covering its skeleton. These "pants"-like feathers may be used for display, camouflage, and insulation rather than primarily for flight, and may help stabilize the creature during landing.
