Finally, during the Late Cretaceous Period, dinosaurs continued to diversify, with the Cenomanian stage seeing the rise of hadrosaurs such as Eolambia, and Protohadros, as well tyrannosaurs such as Moros intrepidus, which would eventually replace the carnosaurs, like Siats, as the continent’s apex predators.
Allen Formation (Late Cretaceous, Campanian to Maastrichtian) Argentina: Its holotype was preserved with two eggs that may have been within its oviducts when it died [17] Bonapartesaurus: 2017 Allen Formation (Late Cretaceous, Campanian to Maastrichtian) Argentina: Belongs to the Austrokritosauria, a clade of hadrosaurids endemic to South ...
Referred specimens were found in Canada [119] and Russia, [120] making it one of the few Late Cretaceous non-avian dinosaur taxa known from both Asia and Laramidia Qiupanykus: 2018 Qiupa Formation (Late Cretaceous, Maastrichtian) China: May have used its robust thumb claws to crack open oviraptorid eggshells [121] Quaesitosaurus: 1983
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after creta, the Latin word for the white limestone known as chalk.
The Cretaceous is divided into Early and Late Cretaceous epochs, or Lower and Upper Cretaceous series. In older literature, the Cretaceous is sometimes divided into three series: Neocomian (lower/early), Gallic (middle) and Senonian (upper/late). A subdivision into 12 stages, all originating from European stratigraphy, is now used worldwide. In ...
Patagopelta (meaning "Patagonian shield") is an extinct genus of ankylosaurian dinosaur from the Late Cretaceous (upper Campanian–lower Maastrichtian) Allen Formation of Argentina. The genus contains a single species, P. cristata, known from a partial skeleton.
Restoration. The fossil remains of Mapusaurus were discovered in a bone bed containing at least seven to possibly up to nine individuals of various growth stages. [2] [11] [12] Coria and Currie speculated that this may represent a long term, possibly coincidental accumulation of carcasses (some sort of predator trap) and may provide clues about Mapusaurus behavior.
