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.
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 ...
This meant weaker global winds, which drive the ocean currents, and resulted in less upwelling and more stagnant oceans than today. [56] This is evidenced by widespread black shale deposition and frequent anoxic events. [21] Tropical SSTs during the late Albian most likely averaged around 30 °C.
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 ...
“Dinosaurs had not yet emerged at this time, but the animals responsible for the largest footprints here would still have been impressive, reaching up to 2-3 meters in length,” said Cristiano ...
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 ...
The latest dinosaur being mounted at the Natural History Museum in Los Angeles is not only a member of a new species — it's also the only one found on the planet whose bones are green, according ...
