Sedimentary organic matter
Okay kiddo, let's talk about sedimentary organic matter. Imagine that you are at the beach and you build a sandcastle. The sandcastle is made up of small grains of sand that are stacked together. Now, imagine that instead of sand, you have lots and lots of little bits of plants and animals that have been squished and buried over time under more and more layers of mud and dirt. These bits are called sedimentary organic matter.
When plants or animals die, their bodies may not decompose all the way. Some parts, like leaves or shells, don't break down easily and can get buried in sediments. Over time, these layers of sediment build up and the organic matter becomes compressed and squished together. This is what forms sedimentary rocks, like shale and limestone.
The organic matter in sedimentary rocks can tell scientists a lot about Earth's history. For example, if we find lots of plant material, it could be a sign that the area was once a lush forest or marsh. Or, if we find lots of marine shells, we know that the area used to be covered by water.
So, sedimentary organic matter is kind of like a time capsule that tells us about what was happening on Earth a long, long time ago!
