Dino Discoveries Through Time And Fossils

Jessi and Dino explore the fascinating world of dinosaurs, discussing their diets and the different time periods they lived in. They explain that dinosaurs like Stegosaurus and Triceratops did not coexist, as they lived in different eras. Using a body model, they illustrate the vast timeline of dinosaur existence, from the Triassic to the Cretaceous period. The video also covers how fossils provide clues about the past, using a recycling bin analogy to explain how deeper fossils are older. The video concludes with an invitation to continue learning with SciShow Kids.

How long did the Jurassic period last?

• About 20 million years

• Over 50 million years

• Less than 10 million years

• Around 100 million years

In the body model, what does the distance from the chest to the top of the head represent?

• Over 100 million years

• About 6 million years

• Less than 1 million years

• Around 50 million years

What is one way scientists determine the age of fossils?

• By how deeply they are buried

• By their size

• By their location

• By their color

What analogy is used to explain how fossils are buried over time?

• A layered cake

• A recycling bin

• A pile of leaves

• A stack of books

What do fossils help scientists understand?
