Prettige feite

Judinornis was a member of the Hesperornithes, a group of flightless, toothed seabirds from the Cretaceous period.1

Unlike many of its relatives that lived in the sea, Judinornis lived in rivers and estuaries in what is now Mongolia.1

Judinornis probably lived about 70 million years ago, during the early Maastrichtian stage of the Late Cretaceous.1

Its fossils were found in the Nemegt Formation, which was formed from sediments deposited by rivers in a dry landscape.1

Judinornis is known from only a single species, Judinornis nogontsavensis.1

Vir dino-kenners

Wetenskaplike naam: Judinornis
Benoem deur: Nessov and Borkin 19832
Groep: Vroeë voëls
Familie / klade: Baptornithidae2
Klassifikasie: Theropoda > Avialae2
Ouderdom van die rotse: 72 tot 66 miljoen jaar (Maastrichtian)2
Rotsformasies: Beds of Nogon Tsav2
Lande: Mongolië2
Fossielrekords: 1 in The Paleobiology Database2
Ontdekking: Judinornis was named by Lev Nessov and L. Y. Borkin in 1983, based on a fossil found at Nogon Tsav in Mongolia.2 1
Steeds omstrede: Scientists are not sure exactly how Judinornis is related to other hesperornithine birds, but it appears to have been one of the more basal members of the group.1
