ELI5: Explain Like I'm 5

Paleozoology

Paleozoology is like being a detective but instead of solving crimes, we are trying to figure out what animals were like a really long time ago. And when I say a really long time ago, I mean like millions and millions of years ago when dinosaurs were around.

First, we need to find fossils which are the remains or imprints of plants and animals that are preserved in rocks. If we find a fossil of an animal, we can tell a lot about it just from the bones or teeth it left behind.

We can figure out what kind of animal it was, how big it was, what it ate and how it lived. For example, if we find big sharp teeth, we can guess that the animal was a predator who ate other animals. But if we find flat teeth, we can guess that the animal was a plant-eater.

Paleozoologists study these fossils to learn more about how animals have changed over time and how they have adapted to new environments. It's like looking at a big puzzle and trying to put all the pieces together to see the big picture of what the world was like in the past.

So paleozoology is a really cool way for us to learn about the animals that lived long before we were around and to understand more about the history of our planet.
