The mass extinction over the last 500,000 years marks major climatic and moderate productivity changes. Between 200 and 400 kyr before the K–T boundary, surface and deep waters warmed rapidly by 3–4 °C and then cooled again during the last 100 kyr of the Late Cretaceous.
Cowboys vs. Dinosaurs: Trek tells the story of a wild west deputy who has to contend with a wanted Therizinosaurus. Survival of the Biggest: Penelope's cold forces her to stay inside on the day Trek asks her to help research dinosaurs, but with her help, Trek learns why so many different dinosaurs stick together in a large mixed herd ...
Bistahieversor (meaning "Bistahi destroyer"), also known as the "Bisti Beast", is a genus of basal eutyrannosaurian theropod dinosaur. The genus contains only a single known species, B. sealeyi , described in 2010, from the Late Cretaceous [ 1 ] of New Mexico.
The Cretaceous–Paleogene (K–Pg) extinction event, [a] also known as the K–T extinction, [b] was the mass extinction of three-quarters of the plant and animal species on Earth [2] [3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.
Nanosaur is a science fiction third-person shooter video game developed by Pangea Software and published by Ideas From the Deep for Mac OS 9 and Microsoft Windows.The player takes on the form of a Nanosaur, a genetically engineered intelligent dinosaur from the future, sent back in time just prior to the Cretaceous–Paleogene extinction event.
Definite evidence of Late Cretaceous sauropods in North America was first discovered in 1922, when Charles Whitney Gilmore described Alamosaurus sanjuanensis. [1] The term "sauropod hiatus" was coined by researchers Spencer G. Lucas and Adrian P. Hunt in 1989 to describes how fossils of the clade become scarce in western North America near the beginning of the Late Cretaceous.

A study aiming to quantify the habitat of latest Cretaceous North American dinosaurs, based on data from fossil occurrences and climatic and environmental modelling, and evaluating its implications for inferring whether dinosaur diversity was in decline prior to the Cretaceous–Paleogene extinction event, was published by Chiarenza et al ...
