名字的意思： “Tacuadactylus means 'Tacuarembó finger', named after the place where it was found and the Greek word for finger.”1

吃：魚飛行爬蟲類侏羅紀晚期到白堊紀早期嚴格來說不是恐龍

Tacuadactylus was a flying reptile that lived about 150 million years ago. It had a long snout with many small teeth, perfect for scooping up fish. It was one of the first pterosaurs ever found in Uruguay!1

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。

趣味知識

Tacuadactylus was first mistaken for a sawfish! In 2016, scientists thought the snout belonged to an ancient fish, but a CAT scan showed it was actually a pterosaur.1

Its teeth were not straight up and down. They pointed forward and to the sides, which is unusual.2

Tacuadactylus had about 1.58 to 2 teeth per centimeter of jaw, making it a very toothy creature.2

It was the oldest known ctenochasmatid pterosaur from South America when it was named in 2021.1

The name 'luciae' honors the daughter of one of the scientists who described it.1

Tacuadactylus lived during the Late Jurassic, about 152 to 145 million years ago.1

迷思破解王

迷思： Some people might think Tacuadactylus was a dinosaur because it lived long ago and had wings.

真相： Tacuadactylus was a pterosaur, a flying reptile, not a dinosaur. Pterosaurs are a separate group of reptiles.1
