Prettige feite

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

KI-prent van Pasquiaornis — 'n KI-prent van hoe Pasquiaornis dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Pasquiaornis
Benoem deur: Tokaryk et al. 19972
Groep: Vroeë voëls
Familie / klade: Hesperornithiformes2
Klassifikasie: Theropoda > Avialae2
Ouderdom van die rotse: 100 tot 94 miljoen jaar (Cenomanian)2
Rotsformasies: Belle Fourche2
Lande: Kanada2
Fossielrekords: 2 in The Paleobiology Database2
Ontdekking: 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
Steeds omstrede: 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
