the quill that grounded dinosaurs and let evolution finally take flight
means One of the light, flat, branching structures that cover a bird's body, made of keratin and used for flight, insulation, and display.
from From Old English 'fether,' tracing back to a Proto-Indo-European root '*pet-' meaning 'to fly' or 'to rush'—the same root that, through Latin and Greek, gives us 'petition' (a rushing toward) and the '-pter' in 'helicopter' and 'pterodactyl.' So a feather is, at heart, simply 'the flying thing,' and its name has been airborne for thousands of years.
