Fossils Uncovered: Types, Formation, and Mary Anning's Legacy

Angelina Crittenden, a TA for the USC Young Scientist Program, introduces the concept of fossils, explaining that they are preserved specimens from living organisms. She describes four types of fossils: trace, mold, cast, and true form. The video includes a hands-on activity to recreate trace and true form fossils using Play-Doh and leaves. The session concludes with a highlight of Mary Anning, a pioneering fossil hunter, and encourages viewers to explore more resources.

What is a fossil?

• A type of plant

• A type of rock

• A type of dinosaur

• A preserved specimen from a living organism

Which of the following is NOT a type of fossil?

What do trace fossils show?

• A negative space imprint of the organism

• The pattern of movement of an organism

• A positive space imprint of the organism

• The entire organism preserved

How is a cast fossil formed?

• By filling a mold fossil with sediment or minerals

• By capturing the movement of an organism

• By leaving a negative space imprint

• By preserving the entire organism

What materials are needed to create a trace fossil at home?

• Clay and water

• Play-Doh and paper

• Sand and glue
