How did ancient monsoons create a dinosaur fossil site?

Long ago, huge storms washed dinosaur bones into a giant muddy bathtub, turning them into hard stone over millions of years.

Imagine it raining very hard for a long time. This is a monsoon. In ancient times, these storms were super strong. They acted like a giant broom, sweeping up dirt, leaves, and dinosaur remains. The water carried these things to low places, like a calm lake or swamp.

When the water slowed down, the heavy bits sank to the bottom. Think of it like stirring sugar into tea: the sugar (the bone) sinks when you stop stirring. Over time, more mud covered the bone. The weight of the new mud squished the old mud, turning it into rock. This process is called lithification.

The bone did not stay exactly the same. Minerals from the surrounding mud seeped into the bone, filling the tiny holes. This turned the bone into stone, keeping its shape safe inside the rock. We call this a fossil. When we dig them up, we find a dinosaur time capsule. It is like finding a toy buried in a sandbox that has turned into a rock block.
