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

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Pasquiaornis — Umfanekiso owenziwe yi-AI obonisa indlela Pasquiaornis esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Pasquiaornis
Inikwe igama ngu:: Tokaryk et al. 19972
Iqela: Iintaka zokuqala
Usapho / iclade: Hesperornithiformes2
Ukuhlelwa: Theropoda > Avialae2
Ubudala bamatye: 100 ukuya ku-94 izigidi zeminyaka (Cenomanian)2
Izakhiwo zamatye: Belle Fourche2
Amazwe: iKhanada2
Iirekhodi zeefosili: 2 kwi-Paleobiology Database2
Ukufunyanwa: 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
Kusaxoxwa ngayo: 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
