Years before the final day of the dinosaurs, gravitational interactions with Jupiter dislodge the asteroid which will become the Chicxulub impactor from its orbit, sending it on a course for Earth. On a spring morning, 66 million years ago, Tanis was a sandbank on the edge of a river near the Western Interior Seaway.
Note 1 Co-author Mark Richards, a professor of earth sciences focusing on dynamic earth crust processes, [21] suggests that the resulting seiche waves would have been approximately 10–100 m (33–328 ft) high in the Western Interior Seaway near Tanis [1]: p.8 and credibly, could have created the 10 – 11 m (33 – 36 feet) high water ...
While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
Last Day of the Dinosaurs is a 2010 Discovery Channel television documentary about the K-T extinction, which resulted in the extinction of the non-avian dinosaurs. [1] It portrays the Alvarez hypothesis as the cause of extinction. The documentary was released on August 28, 2010 and narrated by Bill Mondy. [2]
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia. [32] [33 ...
Alternatively, interpretation based on the fossil-bearing rocks along the Red Deer River in Alberta, Canada, supports the gradual extinction of non-avian dinosaurs; during the last 10 million years of the Cretaceous layers there, the number of dinosaur species seems to have decreased from about 45 to approximately 12. Other scientists have made ...
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.
Hollow Earth Expedition, inspired by the pulp fiction of Jules Verne, Arthur Conan Doyle, and Edgar Rice Burroughs [1] is a role-playing game set in 1936 in which everything on the surface of Earth appears normal, but an entirely different world replete with dinosaurs, Amazons, 18th-century pirates, [1] Atlantean artifacts, and deadly flora lies beneath the Earth's surface.
