Map showing where Ankylosaurus fossils have been discovered; the holotype is shown in red ( ) Ankylosaurus existed between 68 and 66 million years ago, in the final, or Maastrichtian, stage of the Late Cretaceous Period. It was among the last dinosaur genera that appeared before the Cretaceous–Paleogene extinction event. The type specimen is ...
Paleo Pines received an average critic score of 65 out of 100 from Metacritic, equating to "mixed or average reviews". [7] Ryan Thompson-Bamsey of TheGamer called the game "a largely successful execution of standard farming sim formulas," adding that the dinosaur collecting and caring mechanic was the "most compelling" part of the game.

The Dinosaur Park Formation is the uppermost member of the Belly River Group (also known as the Judith River Group), a major geologic unit in southern Alberta.It was deposited during the Campanian stage of the Late Cretaceous, between about 76.5 and 74.4 million years ago. [3]
A paleo-population study is one of the most difficult of analyses to conduct in field paleontology. Here is the most recent estimate of the proportions of the eight most common dinosaurian families in the Hell Creek Formation, based on detailed field studies by White, Fastovsky and Sheehan. [33] Ceratopsidae 61%; Hadrosauridae 23% ...
Antarctopelta (ann-TARK-toh-PEL-tə; meaning 'Antarctic shield') is a genus of ankylosaurian dinosaur, a group of large, quadrupedal herbivores, that lived during the Maastrichtian stage of the Late Cretaceous period on what is now James Ross Island, Antarctica.

Skeletal mounts of the ankylosaur Scolosaurus. This timeline of ankylosaur research is a chronological listing of events in the history of paleontology focused on the ankylosaurs, quadrupedal herbivorous dinosaurs who were protected by a covering bony plates and spikes and sometimes by a clubbed tail.
Holotype skull of P. grangeri. The American Museum of Natural History sponsored several Central Asiatic Expeditions to the Gobi Desert in Mongolia in the 1920s. Among the many paleontological finds from the "Flaming Cliffs" of the Djadokhta Formation in Shabarakh Usu (Bayn Dzak) were the original specimens of Pinacosaurus, found by Walter W. Granger in 1923.
