the leathery sky-lizard that ruled the air millions of years before the first bird existed

means A pterosaur, especially the genus Pterodactylus — a flying reptile of the dinosaur age with leathery wings stretched along an elongated finger; in casual speech, any prehistoric winged reptile.

from From Greek 'pteron' (wing) plus 'daktylos' (finger) — literally 'wing-finger,' a precise nod to how the membrane stretched from an enormously elongated fourth digit. The naturalist Georges Cuvier coined the Latin 'Ptero-dactyle' in the early 19th century after studying a fossil; the silent 'p' before the 't' is pure Greek inheritance, the same one lurking in 'pterodactyl' and 'helicopter' (a 'spiral-wing' from the same 'pteron').
