This is absolutely beautiful stuff.

It went up and down, and it really started to accelerate around 70,000 years ago.

And one hell of a big pile of dollars.

It's an incredible story.

I'll end up with saying one thing.

That they are Piles of stars stripped away by tidal interactions of galaxies in the cluster.

We used to do it just with ice cores, but in this case, we're going back 20 million years.

So we know there's an ice shelf overhead.

And again, it's this incredibly exciting animal.

And they said scaling, which is the build up of minerals inside of pipes.

An empty formality a piece of parchment.

But gradually, as the buildings are repaired, we will see the accretion of a limestone reef beneath the city.

Now, in this slide the white is chalk, and this chalk was deposited in a warm ocean.

There's two degrees, or three degrees of climate change baked into the system.

So this also turns out to be extremely robust.

You know, we saw this in the core samples as they came up.

We have many initiatives that we're working on, but some of them are very basic.

And it was deposited by the great mother Earth, some three million years ago.

And all that gets into surface waters, eventually reaching the ocean, the final sink.

And the black rock is the sediment on the sea bottom in the absence of plankton.

Well, an excavation was begun immediately, and more and more little bits of skull started to be extracted from the sediment.

But if you break a gourd, you cannot simply throw it away, because every stroke of that stick that has built up that calcium, the measure of a man's life, has a thought behind it.

And these tin particles were deposited on the tape heads and were crashing the tape heads.

And so where there is water, there is a very high chance of our kind of life.

And there's this relentless persistence of birth and death and an unending collection of stories in between.

And 90 percent of our catch were sponges, other animals that are fixed on the bottom.

We go out for months at a time and drill into the sea bed to recover sediments that tell us stories of climate change, right.

And these plants need sunlight, so we know when we find that sediment there's no ice overhead.

So they went to their storage lockers and all gathered their extra furniture gave me pots and pans, blankets everything.

But the new wave of paleontologists my graduate students collect biomarkers.

When that was soiled, they were paid again to collect it.

And they said, you know what happens is, mineral just like at your house mineral builds up.

Some of the scientists believe that the way the Solar System formed, that the Sun when it collapsed and actually created the Sun, a lot of the dust around it created rings and then the particles in those rings accumulated together, and they formed bigger rocks, and then that's how the planets, you know, were formed.

The first one that we see occurs in the ancient rain forests of Australia about 25 million years ago, and the National Geographic Society is helping us to explore these fossil deposits.

They give rise to the trees, they create the debris fields that feed the mycelium.

And those are the peat swamp forests on 20 meters of peat, the largest accumulation of organic material in the world.

They used the same trash to form green manure.

I love bridges, metaphorically and symbolically and structurally and it was a bit of a disappointment, because of the sludge from the river was encrusted on it it really wasn't in use.

When they pray for the dead, they make these gestures with their hands, spinning their thoughts into the heavens.

And architect Christian Kerrigan has come up with a series of designs that show us how it may be possible to actually grow a limestone reef underneath the city.

This is our protocell technology, effectively making a shell, like its limestone forefathers, and depositing it in a very complex environment, against natural materials.

And we saw about 35 alternations between open water and ice covered water, between gravels and these plant sediments.

So we are tracking how do these things get from the products into the ocean, which is the final sink for them.

Besides, your logo's going to be all over the place.

But the fact is, this is evidence of a living body on other bodies, rocks that have been the subject of geological formation, erosion, the action of time on objects.
