What Caused the End-Cretaceous Mass Extinction?

What Caused the End-Cretaceous Mass Extinction?

Our series on mass extinctions has explored Earth’s five mass extinctions: the End-Ordovician, the Late Devonian, the End Permian, the End-Triassic, and the End-Cretaceous (K-Pg) extinction.  We are at the last mass extinction event. What caused the End-Cretaceous mass extinction? The End-Cretaceous mass extinction was caused by a 6-9 mile (10-14 kilometer) asteroid striking Earth near Mexico’s Yucatán Peninsula 66 … Continue Reading

What Caused The End-Triassic Mass Extinction

What Caused the End-Triassic Mass Extinction?

The End-Triassic mass extinction represents a pivotal moment in Earth’s history. Often overlooked, this event fundamentally reshaped life on our planet by clearing the way for dinosaurs’ rise. It was significant as it would be the last mass extinction until the end of the Mesozoic. So what caused the End-Triassic mass extinction? The End-Triassic mass extinction was triggered by extensive … Continue Reading

What Caused The End Permian Mass Extinction

What Caused the Permian Mass Extinction?

In our series on mass extinctions, we’ve explored two significant events: the End Ordovician and Late Devonian mass extinctions. During these mass extinctions, many species disappeared. However, life showed remarkable resilience, bouncing back relatively quickly. Imagine comparing Earth’s species just before these mass extinctions to those present a few million years after each event. You might be surprised to find … Continue Reading

What Caused the Late-Devonian Mass Extinction

What Caused the Late Devonian Mass Extinction?

The Devonian period was characterized by fish diversification and the emergence of tetrapods. All this ended abruptly as various factors contributed to a radical die-off of most marine life. The consequences of this mass extinction were far-reaching, altering the evolutionary trajectory of vertebrate life and restructuring marine ecosystems. What could have triggered such a massive and targeted extinction? About 375 … Continue Reading

why were dinosaurs discovered so late

Why Were Dinosaurs Discovered So Late?

Most of us know that humans and dinosaurs did not coexist. So when did people first know about dinosaurs? 2024 marks 200 years since the first dinosaur was described.

William Buckland … Continue Reading

how long does it take for fossils to form

How Long Does it Take for Fossils to Form?

The fossilization process is a remarkable phenomenon. It allows us to study the forms of life that inhabited our planet millions, and even billions, of years ago. From the smallest microorganisms to the mightiest dinosaurs, fossils offer an unparalleled glimpse into the past, preserving the intricate details of ancient creatures and ecosystems. The oldest fossils are around 4 billion years … Continue Reading
