They documented a 7.8±3.3 °C warming synchronous with the onset of Deccan Traps volcanism and a second, smaller warming at the time of meteorite impact. They suggested that local warming had been amplified due to the simultaneous disappearance of continental or sea ice.
The coelurosaur dinosaurs found there represent types of the group Maniraptora, which includes modern birds and their closest non-avian relatives, such as dromaeosaurs, oviraptorosaurs, therizinosaurs, troodontids along with other avialans. Fossils of these dinosaurs from the Liaoning lagerstätte are notable for the presence of hair-like feathers.
A mass extinction event that brought about the rise of the dinosaurs more than 200 million years ago was believed to be caused by the planet’s warming. Now, scientists at Columbia University say ...
The global climate of the Paleogene transitioned from hot and humid conditions of the Cretaceous to a cooling trend which persists proceeded today, perhaps starting from the extinction events that occurred at the K–T boundary. This global cooling has been periodically disrupted by warm events such as the Paleocene–Eocene Thermal Maximum ...
The CTM is notable for its dramatic increase in global temperatures characterized by high carbon dioxide levels. A graph depicting data from the Phanerozoic Geological era, showing oxygen isotopes from present to 500 Ma. The isotope levels show an correlating increase in global temperatures due to glaciation and glacial retreat.
The small dinosaur eggs, discovered in 2021, represent an entirely new species, due to their unique features. 80-million-year-old dinosaur eggs dug up in China are the smallest ever found Skip to ...
When the last ice age ended thousands of years ago, the rate of global warming — which was roughly 10 times slower than what we see today — was rapid enough to wipe out entire species.
The largest, youngest and most completely known megaraptoran Malarguesaurus: 2008 Portezuelo Formation (Late Cretaceous, Turonian to Coniacian) Argentina: Large and robustly built Manidens: 2011 Cañadón Asfalto Formation (Early Jurassic, Toarcian) Argentina: May have been arboreal due to the structure of its feet, with toes adapted for ...
