Learn about two major asteroid impacts from 3.5 million years ago that may not have had lasting environmental effects.

To garner the results of this study, the research team looked at the impacts of two major asteroids from the late Eocene epoch (about 38 million years to 33 million years ago). One created the 60-mile ...

Thirty-four-million years ago, Earth changed profoundly. What happened, and how were Earth's animals, ... with a sharp temperature drop of about two degrees Celsius in the Late Eocene.

No paleoclimatic anomalies are associated with the late Eocene extraterrestrial impact events. Communications Earth & Environment , 2024; 5 (1) DOI: 10.1038/s43247-024-01874-x Cite This Page : ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

Between 34 million to 44 million years ago, an epoch known as the middle-to-late Eocene, Earth's atmosphere transformed drastically. As carbon dioxide levels plummeted, global cooling triggered ...
