One small step for a "Homo snackiens"....many steps for a couple of dinosaurs.

Astronauts' bootprints on the Moon will stay fresh for a long time.

No rain, no wind - so only tiny meteorites might disturb these imprints.

Amazingly, footprints of other kinds of creatures have survived on the Earth.

This can be because they were quickly covered by volcanic ash, or other layers of fine material, preserving the details.

These footprints were most likely made by Australopithecus afarensis, an early human whose fossils were found in the same sediment layer.

They were found at Laetoli in Tanzania.

Looking at much older rocks, footprints of dinosaurs can be used to find out all sorts of things about their lives.
