Egg fossil

An egg fossil is a very old egg that has turned into stone over millions of years.

Imagine you have a plastic egg in your hand, and you want to keep it safe forever. Instead of putting it in a box or a drawer, you bury it in the ground.

Now, fast forward millions and millions of years. The ground has shifted and changed, and the egg you buried is now deep underground. Over time, the egg loses all its squishiness and water, and it becomes rock-like.

Finally, someone discovers the spot where you buried your egg all those years ago. They dig it up and find the rock-like egg: that's what we call an egg fossil.

Scientists can study these egg fossils to learn about the animals that laid the eggs. Just like how you can tell who made cookies by looking at the shape, color, and texture, scientists can tell what kind of animal made an egg by looking at its fossil.
