150-Million-Year-Old Archaeopteryx Fossil Reveals Evolution of Powered Flight

Key facts

• Scientists have analysed a 150-million-year-old Archaeopteryx fossil from the Jurassic period that serves as a critical evolutionary link between dinosaurs and modern birds.
• The Archaeopteryx specimen possesses a unique mix of anatomical features, including bird-like wings and feathers combined with dinosaur-like teeth, claws, and a long tail.
• A report by the Natural History Museum of Utah (NHMU) indicates that specialised feathers acted as an aircraft fairing to fill the gap between the wing and torso to prevent turbulent drag.
• The fossil evidence suggests that Archaeopteryx was capable of active powered flight rather than simple gliding, proving that complex flight mechanics were present during the Jurassic era.
• Research published in The Royal Society highlights that early birds developed advanced feeding adaptations and complex mouth structures alongside flight capabilities to enhance survival.
