Pterodactylus (pron.: /ˌtɛrəˈdæktɨləs/ terr-ə-dak-til-əs, from the Greek πτεροδάκτυλος,pterodaktulos, meaning "winged finger" /ˌtɛrəˈdæktɨl/) is a genus of pterosaurs, whose members are popularly known as pterodactyls. It was the first to be named and identified as a flying reptile. Its fossil remains have been found primarily in the Solnhofen limestone ofBavaria, Germany, dated to the late Jurassic Period (early Tithonian), about 150.8-148.5 million years ago,[1] though more fragmentary remains have been identified from elsewhere inEurope and in Africa. It was a carnivore and probably preyed upon fish and other small animals. Like all pterosaurs, the wings of Pterodactylus were formed by a skin and muscle membrane stretching from its elongated fourth finger to its hind limbs. It was supported internally by collagen fibres and externally by keratinous ridges. The name derives from the Greek words pteron (πτερόν, meaning 'wing') and daktylos(δάκτυλος, meaning 'finger') and refers to the way in which the wing is supported by one large finger.
