名字的意思： “lake wanderer”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Lacusovagus was a big flying reptile that soared over ancient Brazil. It had no teeth and no crest on its head, which made it different from many other pterosaurs. It was the largest pterosaur found in the Crato Formation.1 2

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

Lacusovagus had a long, wide skull and a short snout in front of its big nasal opening.1

It was toothless, which is unusual for pterosaurs from the Crato Formation.1

Its wingspan was about 4 metres (13 feet), making it the biggest pterosaur known from the Crato Formation.1

Lacusovagus weighed around 30 kilograms (66 pounds), similar to a large dog.1

Scientists think it belonged to a group called Chaoyangopteridae, but some studies place it with Tupuxuara or Tapejaridae.1
