Study Notes
Fossil Types
- A footprint in the mud that hardens can become a fossil, specifically a trace fossil, which is evidence of animal activity that is preserved.
- Body fossils are the remains of plants or animals that were trapped under dirt and preserved over a long period of time.
Characteristics of Fossils
- Fossils must be over 10,000 years old to be considered as such.
- The word "fossil" comes from the Latin word fossilis, meaning "dug up."
Where Fossils are Found
- Most fossils are found in sedimentary rock, which is formed by compressed dirt, sand, silt, or clay.
- Sedimentary rocks like limestone and sandstone commonly have fossils.
- Fossils can also be found in amber, which is formed when resin from trees is preserved with a plant or animal trapped inside.
Formation of Fossils
- Plants and animals get stuck in layers of sediment for thousands of years, creating fossils.
- Minerals harden around the shape of the plant or animal, and the actual remains are washed away, leaving molds of the organisms.
Locations of Fossil Findings
- Fossils are often found in high desert regions, such as in the western United States, Argentina, and China, due to the lack of organic matter covering the ground.
Other Types of Fossils
- Fossil poop, also known as coprolite, is a type of fossil that provides information on the animal it came from.
- Coprolites have been found from various animals, including dinosaurs, crocodiles, fish, insects, and humans.
