We see rocks all around us. From the little pebbles to the big boulders, all of them share one common feature. Their preservation power. This power holds all of the Earth’s history. Before we learn about the most recent examples of this superpower, let’s learn about how the rocks acquired this power.

Erosion

When wind or water erodes rocks, the river picks up the eroded sediment. These sediments are deposited over the course of the river. Eventually, an animal or an organism will die in the river. Over very long periods of time, the rock preserves the organism’s bones and other features. Since there is nothing disturbing it, and there are so many layers of rock over it, it takes lots of time to uncover such a discovery.

What about discoveries that happened recently?

Archaeologists, who study the preserved remains of human history, often find cool discoveries in rock. Recently, they found a 2,000-year-old Roman mosaic. This wasn’t in Italy, but in London instead. This was because the Roman Empire spanned nearly all of Europe. Archaeologists suspect it could be part of a large Roman dining room, which explains the intricate designs that they found. Like most preserved artifacts, this one was found by accident. In fact, a regeneration project in London uncovered this mosaic.

In another case, archaeologists uncovered an 11,000-year-old cave art. They assume it depicted ancient animals that were ancestors of current animals. Others argue that this art is more recent, saying that it could be based on later ancestors of current animals. While the age of this art is controversial, it is undoubtedly important to discovering more about our planet’s history.

Overall, rocks aren’t just any non-living object. They are the preservers of our history, and they hold power. When this power is summoned, we are enlightened to the beautiful sceneries that our ancestors took in.
