Amazing dinosaurs tracks

How would you like to go back in time millions of years?

One place in the world offers an amazing spectacle: it's Cal Orko, Sucre, Bolivia.  A huge limestone wall there is proving to be a treasure trove for paleontologists.   It preserved on its rock face thousands of large tracks from a remarkable variety of dinosaurs.

The wall used to be a shallow lake bed, but when the Andes Mountains were formed, the lake bed became a vertical feature. The now climbing tracks are quite amazing.  They date back to the Late Cretaceous period, almost 70 million years ago, and include some astounding tracks made by a baby Tyrannosaurus Rex.
