Restoration of Zhuchengtitan zangjiazhuangensis from the Late Cretaceous of China

Qunkasaura is a titanosaurian sauropod dinosaur that lived approximately 75 million years ago in the Late Cretaceous of what is now Spain. Specifically, it is a saltasaurid titanosaur, and its discovery marks the first instance of two distinct lineages of this group present in the same locality. In the Late Cretaceous, Europe was a large archipelago, and the coexistence of these differing lineages indicates that saltasaurids arrived in the Iberian Peninsula much later than other groups of dinosaurs.

Saltasaurus (which means "lizard from Salta") was a sauropod dinosaur of the Late Cretaceous Period. Relatively small among sauropods, though still massive by human standards, it was characterized by a diplodocid-like head

The Maastrichtian, Transylvanian giant azhdarchid pterosaur Hatzegopteryx sp. preys on the rhabdodontid iguanodontian Zalmoxes. Because large predatory theropods are unknown on Late Cretaceous Haţeg Island, giant azhdarchids may have played a key role as terrestrial predators in this community.

Locality map: Grand Staircase-Escalante National Monument, southern Utah. Map showing the Nipple Butte area (indicated by yellow star) of Grand Staircase-Escalante National Monument (GSENM). GSENM is bounded by the red rectangle and silhouetted in dark gray on the inset of Utah and surrounding states (modified from [1]). The original map has been modified to show the Nipple Butte area instead of the Machairoceratops fossil locality as in the original source. New location based on map in A New Macrovertebrate Assemblage from the Late Cretaceous (Campanian) of Southern Utah, page 601.
