名字的意思： “Alamo finger, named after the Alamo symbol of Texas independence”1

吃：魚飛行爬蟲類白堊紀晚期嚴格來說不是恐龍

Alamodactylus was a flying reptile that soared over Texas about 88 million years ago. It had long, narrow wings and probably glided over the sea to catch fish. It was not a dinosaur, but a pterosaur, a close cousin of dinosaurs.1 4

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

酷東西

趣味知識

Alamodactylus is known from only one partial wing, including a humerus and other bones, found in Texas.1

Its name means 'Alamo finger' because the fossil was found in Texas, the 'Alamo' state, and pterosaurs often have 'finger' in their names due to their long wing digits.1

Scientists think it was a medium-sized pterosaur, but they don't know its exact size because only a few bones have been found.1

The fossil was first thought to be from a Pteranodon, but later study showed it was a new kind of pterosaur.1

Alamodactylus lived about 89.8 to 88 million years ago, during the Late Cretaceous period.1

Its wing bones show a unique combination of features, like a constricted humerus shaft and a D-shaped cross-section, that set it apart from other pterosaurs.1

發現: The fossil was discovered by Gary Byrd, who it is named after, and first described in 2010. It was given its own genus and species name, Alamodactylus byrdi, by Brian Andres and Timothy Myers in 2013.1
仍有爭議: Scientists still debate exactly where Alamodactylus fits in the pterosaur family tree. Some studies place it close to Pteranodon, while others put it in the Nyctosauridae group.1
