吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Limnornis was a flying reptile that lived about 143 million years ago. It was a pterosaur, not a dinosaur, and it probably ate fish. Its fossils were found in Romania.3 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。

酷東西

趣味知識

Limnornis was first thought to be a bird, but scientists later realized it was a pterosaur, a flying reptile.1

The name Limnornis was already used for a bird called the curve-billed reedhaunter, so the pterosaur got a new name: Palaeocursornis.1

Only one bone of Limnornis has been found, a piece of a leg or arm. That makes it hard for scientists to know exactly what it looked like.1

Limnornis lived on a warm, wet archipelago of volcanic and coral islands, similar to the Caribbean or Indonesia today.1

The habitat of Limnornis had hills, caves, rivers, lakes and swamps.1

迷思： Limnornis was a dinosaur.

真相： Limnornis was a pterosaur, a flying reptile that is not a dinosaur.1

給恐龍專家

學名: Limnornis
命名者: Kessler and Jurcsák 19843
類群: 飛行爬蟲類
科 / 演化支: Pterosauria3
分類: Pterosauria3
岩石的年代: 143 到 137 百萬年 (Berriasian)3
化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Limnornis was named by Kessler and Jurcsák in 1984 based on a single bone found in a mine at Cornet near Oradea, Romania.3 1
仍有爭議: Scientists are not sure if Limnornis is a valid genus because the only fossil is very incomplete. Some think it might be a tapejaroid pterosaur, but others consider it a nomen dubium (doubtful name).1
