Unearthing the Carnian Pluvial Episode— A Prehistoric Adventure

What Is the Carnian Pluvial Episode (CPE)?

The Carnian Pluvial Episode (CPE) is a short but explosive interval in the Late Triassic period, roughly 232 million years ago. "Pluvial" means rainy, and this wasn't just a drizzle — Earth went through a massive, chaotic climate shift. Think: volcanic eruptions, greenhouse gases spiking, monsoon-like rains flooding arid landscapes, and ecosystems going into full evolutionary panic mode.


Why It Matters

Climate Chaos = Evolution Explosion

The CPE led to mass extinctions of older species but also gave rise to modern ecosystems — most importantly, dinosaurs began to dominate right after this epoch. Prior to that, they were just one of many reptilian side-characters.In short:

The CPE was a game-changing, extinction-sparking, evolution-driving climatic freakout.

This episode represents a crossroads of life — early mammals, crocodilian ancestors, and dinos were all scrapping it out for dominance.
 

New Habitats, New Niches

Why This Expedition Is a First

With the rain came lush vegetation and new environments. This allowed species to diversify at an insane rate, setting up the Age of Dinosaurs — the Jurassic and Cretaceous periods that followed.

Until now, most CPE fossil evidence has been found in South America, especially Brazil. It’s one of the few places where the unique sediment layers from this epoch were preserved. But this expedition? We're now potentially uncovering CPE-era fossils in the Northern Hemisphere — Portugal, to be exact.

If confirmed, this would be:


The among the first evidence of the Carnian Pluvial Episode north of the equator
 

A sign that the climate event was global, not regional
 

A massive opportunity to find new species that evolved in different conditions

Who’s Leading the Charge?

This isn’t just about finding a dinosaur bone and high-fiving over it. This is about:


Filling in one of Earth’s most important evolutionary gaps
 

Mapping how climate change shaped the future of life on Earth
 

Understanding what happens when ecosystems collapse and rebound
 

...which makes it eerily relevant for today's world too.
