This is absolutely beautiful stuff.

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

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.

An empty formality a piece of parchment.

And one hell of a big pile of dollars.

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

I thought that might help.

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

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

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.

They take the sediment itself, they extract the oil from it, and from that they can produce compounds which turn out to be very specific to particular microbial groups.

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

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

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

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

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

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

It is a perpetual impulse that pushes galaxies apart from each other.

And that is very easy, we can achieve fusion of anything...

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.

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

So this is these are fertilizer gas plants.

That signal was so strong, it could only have been produced by 10 trillion tons of water buried in the sediment, collected over millions and billions of years by the impact of asteroids and comet material.

It peaks in early adolescence.

Substance D.

Nuclear.

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

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