249-million-year-old fossil shakes up evolutionary timeline

Reanalyzed Arctic fossils show marine ecosystems recovered with astonishing speed after the 'Great Dying'

The Forgotten Creatures Who Ruled Before the “Great Death”

Researchers have uncovered in "Southern Pangaea" (now the southern part of Africa) fossils of creatures that lived shortly before the event known as the "Great Dying," which wiped out about 70% of terrestrial species and an even larger proportion of species

The CO2-Driven Climatic Roller Coaster: A 485-Million-Year Journey

A new study published in the journal Science detailed the fluctuations in the Earth's temperature over the past 485 million years, and highlighted the significant relationship between the Earth's temperature and the levels of carbon dioxide in the atmosphere

The asteroid that wiped out the dinosaurs was a carbonaceous asteroid

This asteroid, which led to the extinction of the dinosaurs, came from a C-type asteroid that originated beyond Jupiter, thus ruling out other hypotheses such as volcanic activity or comets
