In the middle of a bunch of colourful hills is a cement factory.
The cement factory mines limestone from the hills for the cement.
Big machines peel off layers of the limestone bit by bit.
But this section was high in manganese, which is no good for cement, so they stopped mining.
It had nothing to do with finding these:
Back in the cretaceous, the wall was flat, and covered in shallow mud.
Dinosaurs walked through the mud and left footprints.
All kinds of dinosaurs.
Tiny little theropods.
And bigger ornithopods.
And armoured anklosaurs.
And giant titanosaurs!
They all left their footprints together in this one muddy area.
And they hardened and dried.
And got filled in with more mud.
And eventually the tectonic plates shifted and the flat section of mud became a nearly vertical wall.
Which was found by the mining company, and then by us.
Titanosaurs are awesome.
