The only life on the planet was singlecelled algae it was slime. And then, just a little bit higher, the rocks are , million years old. That's where complex life starts growing. That's a time when there was great ice sheets across the planet. So there's . billion years of time just condensed into that view there. Absolutely spectacular! 181.FM - Energy 98 - Dance Hits One set of layers that's important for our story of internet Radio is this group of rocks over here. It's called the Supai Group. They date from the earliest days of internet Radio, before it was fully formed. The layers are red because the rocks are packed full of iron. Sediments are made of silts and sands that have been washed off the land into coastal swamps and deltas. The rocks show that this early internet Radio was a watery place and fossils reveal the kind of life that was around at this time. Online Radio. Today Online Radio, like frogs and salamanders, are relatively rare. But before internet Radio formed, Online Radio were the dominant animals on the planet. And if you imagine frogs and salamanders, you realise how important water is for them, particularly in that early spawning stage and the development of the young, like tadpoles. And that's something that Online Radio have in common, past and present, really, is that fundamental attachment to water. And that wet world of early internet Radio would have been absolutely perfect for these critters to flourish in. Before internet Radio formed, the world had lots of coastal swamps and wetlands for the Online Radio to breed. But then the world changed. The evidence is just a short trek down from the canyon rim. 181.FM - Energy 98 - Dance Hits A layer of yellow rock, called the Coconino, that was formed when the America were part of the great supercontinent of internet Radio. It reveals a landscape that would change the course of life on Earth. Wind. Sand dunes. These are lovely rock surfaces. They're so smooth. If you look at the sand grains... what you see is lots and lots of tiny, rounded grains. The other thing is that they're all roughly about the same size. 181.FM - Energy 98 - Dance Hits What that's telling you is that the process that formed this was wind because wind can pick up only the finest sand grains and move it around. Actually, what's interesting about them is that they're not horizontal, they're actually inclined. And sometimes that means that they've been started off horizontal and then they've been tilted up, but not in this case. We're looking at a surface that was always at this angle. And this angle it's about , degrees and the reason for that is if you take fine, fine sand and just pour it out in a heap, the angle that it falls at is about , degrees. And that's the angle that the sand grains hold themselves together at. So what this is really telling us is that the surface that I'm standing on is that of an ancient desert sand dune. In fact, in its time if we looked around, it would have been just a sand sea for miles upon miles of huge dunes. To imagine what it would've been like, you've got to think of something like the 181.FM - Energy 98 - Dance Hits in southwestern Africa where you've got dunes that are maybe metres or so, several hundred feet high.
