吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Navajodactylus was a flying reptile that soared over what is now New Mexico, USA, about 75 million years ago. It had a wingspan as wide as a small car and probably snatched fish from ancient rivers.1 3

趣味知識

Navajodactylus is known from only a few wing bones, including a piece of the first wing finger phalanx.1

Its name honors the Navajo Nation, combining 'Navajo' with the Greek word for finger, 'daktylos'.1

The holotype fossil was discovered by oceanographer Arjan C. Boeré in 2002.1

Scientists are not sure if Navajodactylus belongs to the azhdarchid family, because its wing bones lack air spaces that azhdarchids usually have.1

Navajodactylus lived about 75 million years ago, during the late Campanian stage of the Late Cretaceous.1 2

Some fossils from Alberta, Canada were once thought to be Navajodactylus, but later scientists assigned them to a different pterosaur called Cryodrakon.1
