00:05Unveiling Archaeopteryx, Journey from Jurassic Lagoons to Modern Birds
00:09A pigeon-sized Archaeopteryx fossil glowed under ultraviolet light in Chicago.
00:14At the Field Museum, paleontologists scanned limestone from Solnhofen, Germany,
00:19where Jurassic Lagoons trapped feathered dinosaurs 150 million years ago.
00:23The Chicago Archaeopteryx arrived from private collectors in 2022,
00:27carrying bones, feathers, and soft tissue inside a pale limestone slab.
00:32Jingmai O'Connor's team used CT scans to trace the skull, spine, hands, feet,
00:36and hidden body details without breaking the fossil.
00:39Preparators worked under ultraviolet lamps because the bones and soft tissues
00:43blended almost perfectly with the surrounding Solnhofen stone.
00:46The fossil showed tertial feathers on the upper arm,
00:49filling the wing gap that modern birds use for smooth flight surfaces.
00:53Archaeopteryx also carried teeth, clawed fingers, a long bony tail, and feathers,
00:58placing dinosaur traits beside bird traits in one body.
01:01Researchers saw foot scales and body tissue that suggested the animal walked on the ground
01:05and climbed through Jurassic branches.
01:08In 1861, the first Archaeopteryx feather surfaced in Germany,
01:12only two years after Charles Darwin published On the Origin of Species.
01:16The Chicago fossil now adds fresh flight evidence,
01:18showing a feathered dinosaur with wings built for more than display.
01:21From a German lagoon to a Chicago museum drawer,
01:24one fragile slab keeps connecting dinosaurs, birds, feathers, and flight.
