Pasquiaornis was a diving seabird that lived in the warm, shallow sea that once covered part of North America. It had teeth in its beak and was a great swimmer, chasing fish and other sea creatures underwater.1

酷東西

趣味知識

Pasquiaornis lived about 95 to 93 million years ago, during the Late Cretaceous period.1

Two species are known: Pasquiaornis hardiei and Pasquiaornis tankei. P. tankei was about one-third larger than P. hardiei.1

Pasquiaornis was a member of the Hesperornithes, a group of toothed, diving birds that were mostly flightless.1

Its wing bones were thickened and not well suited for flying, so scientists think it probably could not fly.1

Fossils of at least 9 individuals were found in a small area, which might mean they lived in colonies or died together in a mass event.1

The rocks where Pasquiaornis was found were once the bottom of the Western Interior Seaway, a shallow sea that split North America in two.1

給恐龍專家

學名: Pasquiaornis
命名者: Tokaryk et al. 19972
類群: 早期鳥類
科 / 演化支: Hesperornithiformes2
分類: Theropoda > Avialae2
岩石的年代: 100 到 94 百萬年 (Cenomanian)2
岩層: Belle Fourche2
國家: 加拿大2
化石紀錄: The Paleobiology Database 收錄 2 筆2
發現: Pasquiaornis was named in 1997 by Tim Tokaryk, Stephen Cumbaa and John Storer. The fossils were collected near Arborfield, Saskatchewan, mostly during 1992 to 1993 expeditions by the Royal Saskatchewan Museum and the Canadian Museum of Nature.1 2
仍有爭議: Scientists are not sure whether Pasquiaornis could still fly, because its wing bones look like those of flying birds but are too thick for good flight.1
