Cretaceous terrestrial revolution. It's a bit of a bombastic term, maybe. But in many ways, it was revolutionary because it touched so many aspects of life and of food webs and of ecosystems. And
Crete is one of these places, much of the Copper Canyons, which has remained frozen in time.
the Cretaceous turned into the Paleocene, the age of dinosaurs, gateway to the age of mammals. But really, this greenhouse world of the dinosaurs persisted. The Earth was still very warm. There
no Cretaceous cassette tape that we can find in the fossil record and plug in, and hear what these things were sounding like. But sometimes we do get clues from the fossils themselves. And in
And Crete is otherwise pretty insignificant.

living in the Cretaceous period. So by the end of the Cretaceous, you would have had some birds that could sound like the birds of today. But it is really just one clue. We need to learn so
or the Cretaceous Paleogene boundary.
This is the end Cretaceous.
At the end Cretaceous, not only is there a gigantic asteroid impact, the biggest that we know of in the last billion years,
and the ruins of Crete.
So what happened on Crete was this.
So you step on Crete on your way there.
But what the Cretans did was unique.
The Butcher of Crete was one guy.

And the high Cretan civilization, the Minoan civilization that they immediately proceeded to overrun, had, among its other attractions, this magical
And this indigenous Cretan script, by the way, which is several centuries older than Linear B but looks a great deal like it, is what we now call Linear A.
They took this indigenous Cretan script, adapted it for use with their own language, and eventually carried it back with them to the mainland.

an animal at the end of the Cretaceous and you ate parts of a growing plant, leaves, flowers, fruits, roots, your food would run out really quickly. But if you could eat seeds, that would be your ticket
At the end of the Cretaceous when an asteroid smashed into the planet and all of the non-avian dinosaurs went extinct, so did most of the cephalopods.
So that's the end Cretaceous.
So at the end of the Cretaceous, people think, oh, the mammals thrived and the dinosaurs went extinct.
and it turns around and goes to Crete, and you have to have an enforced holiday in Crete, when you come back, there is anger.
So if you were a Cretan that morning, you would notice the sky getting dark.

And so what I think the Cretan Runner would have been able to do, what the Cretan resistance was able to do, was tap into this legacy

The largest mammal that's in the latest Cretaceous is about the size of a raccoon.

So interestingly, the end Cretaceous, we think of this big horrible thing.
But the path to Eastern Europe leads through Crete.
The tablets were what Arthur Evans had come to Crete to find.
He had also turned up evidence of a somewhat older Cretan script, which he called, quite reasonably, Linear A. The end
which were the civil documents of an ancient Cretan culture, might contain something similar.
The most recent one, the end Cretaceous extinction of course is responsible for the extinction of the dinosaurs.
