Hello, there! I'm Nekros. I'm going to show you how fossils are made.
This is a river. Rivers carry tiny particles of dirt, mud, silt and rock until they reach a sea or a lake. Here, the rocks are deposited where the water flow slows down.
Fossils are found in sedimentary rocks. Let's see how this forms first.
As more and more deposited rocks are deposited on top, they build up in layers. It takes millions of years for the layers to compact, and when it does, the weight of sediment on the top crushes the sediment at the bottom.
Fossils are usually found in sedimentary rocks such as chalk, limestone, sandstone and shale. These are basically dead animals that were trapped... oh, let me show you:
Great! So that's how sedimentary rocks form. But what about fossils?
Not historically accurate.
Millions of years ago…
But he got stuck in tar...
LOL! I'm gonna kill some little dinosaurs! HAHAHA
I am a stegosaurus
He was right! He did die, and was left there for a long, long time. (Millions of years, to be exact!)
