1980: The Alvarez Hypothesis – Linking Asteroid Impact to Mass Extinction
The Alvarez Hypothesis suggests an asteroid impact caused the mass extinction at the K-Pg boundary, highlighted by the high iridium levels in Italian clay and the Chicxulub crater discovery
c. 65 Million BCE: The Asteroid Impact and the Demise of the Dinosaurs
The extinction of dinosaurs 65 million years ago, marking the Cretaceous-Paleogene boundary, is attributed to a large asteroid impact, evidenced by global iridium deposits. This event led to dramatic climatic changes and the demise of [...]
c. 66 Million BCE: The Deccan Traps – A Volcanic Phenomenon
The Deccan Traps, an example of massive volcanic activity, dramatically altered Earth's landscape and climate, potentially contributing to the mass extinction at the end of the Cretaceous period, showcasing the interplay of gradual and catastrophic [...]
c. 200 Million BCE: The End Triassic Extinction – A Turning Point in Earth’s History
Discusses the End Triassic mass extinction event over 200 million years ago, which led to the extinction of half the species on Earth, including many archosaurs and marine species, paving the way for the rise [...]
c. 252 Million BCE: The Great Dying – Earth’s Largest Mass Extinction
Discusses The Great Dying, the largest mass extinction event around 252 million years ago, which wiped out approximately 96% of ocean species and 70% of land vertebrates, with various hypotheses about its causes and its [...]
c. 450 Million BCE: nderstanding Mass Extinctions in Earth’s History
Delves into the history of mass extinctions, highlighting the catastrophic End Ordovician event 450 million years ago that wiped out up to 85% of species, mainly shallow water and planktonic marine organisms, likely due to [...]
