Silurian

The Silurian was a super long time ago, even before dinosaurs! It lasted for about 23 million years. That’s way longer than you’ve been alive! It happened after the Ordovician period and before the Devonian period. Think of it like a chapter in Earth’s giant history book, right after one chapter and before the next one.

Guess what? During the Silurian, plants decided to try living on land! They grew from simple little things into bigger, stronger plants with special tubes to carry water. It was like the first time plants went on an adventure outside of the water. This was a HUGE deal for our planet!

The oceans were busy too! Fish started to get really cool new features, like jaws! Before this, fish didn't have jaws like we think of them. Some fish even had armor! It was a time of big changes for sea creatures, with some old kinds disappearing and new kinds showing up.

Even though it was so long ago, the Silurian was super important. The plants that started living on land then are the ancestors of all the trees and flowers we see today. And those fish with jaws? They are related to almost all the fish swimming in the oceans and rivers now!
