Picture This!01/31/2019 ● By Ursula Crawford
Back in the 1800s, scientists were wondering the same things. They had found fossils of the scaly, reptile-like dinosaurs that evolved into many of the animals we see on earth today, but no one could figure out where birds came into the picture.
That is, until one fateful day in 1861, in a dusty limestone quarry in southern Germany. An incredible discovery was made: a single fossilized feather, 150 million years old!
Never before had such a specimen been found, and it astounded scientists at the time. Soon after, people began to discover more fossils of these ancient feathered creatures, challenging the previous notion that all dinosaurs were scaly reptiles.
With the claws, teeth, and tail of a reptile and the wings and feathers of a bird, scientists called this creature Archaeopteryx (meaning “ancient wing”) and considered it the evolutionary “missing link” between dinosaurs and birds.
Examining the shape of the fossilized feathers, scientists determined that Archaeopteryx may have used its feathered wings for flying, just like today’s birds. They also found that these feathers contained melanin, the same pigment that gives color to the skin, feathers, or fur of modern animals, including humans. The high levels of melanin found in Archaeopteryx fossils indicate that their feathers were black, making them strong and durable like the black feathers of a raven or a crow.
Although there is a lot we can learn from the shape, size, and pigments in Archaeopteryx’s feathers, there is still a lot we don’t know. What color was the rest of its body? How did it behave? What sounds did it make? What did it eat?
This is where we need a little imagination. We may never be able to see this dino-bird in real life, but with the help of paleoartists—artists who create reconstructions of ancient animals—we can get a better idea of how Archaeopteryx might have looked, lived, and behaved hundreds of millions of years ago.
Since fossils are rarely whole skeletons, paleoartists
sometimes have to make guesses about an animal based on just one fossilized
bone or bone fragment. They start by conducting detailed research into all the
known fossils that we have from a given animal. They also consult with
paleontologists and other scientists who study the fossils today. Using this
information, paleoartists can create sculptures, paintings, drawings, and
digital renderings of animals that lived long ago.

paleoart, and dive into interactive media to learn more about this mysterious feathered
dinosaur and the artists who help bring it to life. The museum is located at 1680 E. 15th
Avenue, on the UO campus. Museum hours are Tuesday through Sunday from 11:00
