1Millions of years ago, a huge and powerful hunter flew in the skies above a former sea in what is now Australia.
2Its large mouth and long, pointed teeth captured fish and other sea life.
3Scientists in Australia recently announced the discovery of fossil remains of the animal, named Haliskia peterseni.
4They said the fossils are the most complete remains of any pterosaur ever unearthed in Australia.
5The creature lived alongside dinosaurs during the Cretaceous Period, the researchers said.
6Haliskia means "sea phantom."
7The researchers said Haliskia's wings measured 4.6 meters across from end to end.
8The animal lived about 100 million years ago.
9"The Eromanga Sea was a massive inland sea covering large parts of Australia when this pterosaur was alive," said Adele Pentland, a doctoral student in paleontology at Curtin University in Australia.
10Pentland was the lead writer of a study, which appeared recently in the publication Scientific Reports.
11The thin bones of pterosaurs do not easily turn into fossils.
12For Haliskia, only 22 percent of the skeleton was unearthed.
13The bones included complete lower jaws, part of the upper jaw, throat bones, 43 teeth, vertebrae, ribs, bones from both wings and part of one leg.
14Pentland said the researchers believe the muscle in the animal's mouth, called the tongue, was very strong, based on the length of its throat bones.
15"In many other pterosaurs, the throat bones are 30 percent or 60 percent the length of the lower jaw, whereas in Haliskia the throat bones are 70 percent the length of the lower jaw," Pentland said.
16Haliskia is a little larger and older, by about 5 million years, than the closely related Australian pterosaur Ferrodraco.
17Scientists announced its discovery in 2019.
18Haliskia's remains are more complete than those of Ferrodraco.
19Both animals belong to a pterosaur group called anhanguerians known from remains found in China, the United States, Brazil, Britain, Spain and Morocco.
20The three other named Australian pterosaurs are known only from partial jaw bones, Pentland said.
21The Haliskia individual's body ended up buried under sediment at the bottom of the Eromanga Sea.
22Pterosaurs were the first of three vertebrate groups to fly, appearing about 230 million years ago.
23Birds appeared about 150 million years ago and bats appeared around 50 million years ago.
24Pentland said the Haliskia discovery is also important because for many years experts believed Australia had very few fossils from the age of dinosaurs.
