The Fossil Record
Fun Facts
- Molds form when buried remains of plants and animals decompose.
- Trace fossils can be molds and casts.
- Molds can fill with minerals, forming cast fossils.
Why Do We Need To Know About Mold Fossils
Learning about mold fossils helps us know more about the history of life on Earth. These fossils are like nature’s snapshots, showing us what the world looked like long ago. This is important for jobs in science like studying old life forms (paleontology), the environment (environmental science), and living things (biology). Knowing about the past helps us understand our world today and plan for the future.
Also, finding and studying mold fossils is useful in other areas like studying rocks (geology), ancient human history (archaeology), and even in building things like roads and buildings (construction and civil engineering). For example, people who study rocks use mold fossils to learn more about how the Earth’s surface was formed. Sometimes, when people are building something, they might find important fossils. Knowing about mold fossils can be important for many different jobs.
