Can fossils be found in dirt?

Dirt on Fossils Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock.

Would fossils near the surface or deep in the ground be older?

Unless the rocks have been turned upside down, and are in horizontal layers, the deeper layers would have been deposited before the layers near the surface, so the deeper layers would contain older fossils than the layers near the surface. All fossils are found near the surface where rocks outcrop.

How is a fossil the same as an artifact?

Fossils are the remains of living things (plants, animals, people), not of things that were made. Artifacts are the remains of things that were made, not the remains of living things.

What are fossils found in?

sedimentary rocks
Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

Why are older fossils found deeper?

Why are the oldest fossils found deeper underground? New rock layers are deposited on top of older ones. New rock layers are deposited on top of older ones.

Are all fossils the same age?

As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils. However, by itself a fossil has little meaning unless it is placed within some context. The age of the fossil must be determined so it can be compared to other fossil species from the same time period.

How are artifacts found?

An artifact is any object that was intentionally designed and shaped through human efforts. Some artifacts are discovered by accident, for example, by a farmer plowing his field or by a construction worker digging a building foundation.

What do artifacts and fossils tell us about the past?

Fossils provide important information about the past life on earth. Based on the types of plants and animals present in a rock unit, scientists can often determine what ancient climates were like as well. Fossils are also useful in correlating and determining the age of rock units.

What is used to determine the age of fossils and prehistoric objects?

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
