Fossils Review 2021

Explain how the fossil was formed.

• The animal or organism left a path, and the mud became hard and fossilized.

• The animal or organism got trapped in tree sap or resin, which hardened over time.

• The animal or organism was buried under layers of soil and sediment, which left an impression of its body over the years.

• The animal or organism was buried rapidly and decayed, and the impression of the shape was filled with sediment and minerals.

Paleontologists (scientists who study fossils) discovered the fossilized remains of an animal. They can tell from its remains that it had gills and fins, but no legs. What conclusion about the animal can they draw from the evidence?

• It was a land animal.

• It lived in the water.

• It had legs that did not get fossilized.

• It lived on both water and land.

How did scientists first learn about dinosaurs?

• by watching movies like Jurassic Park

• by reading books like Dinosaurs Before Dark

• by looking at pictures of a T. Rex

• by studying fossils

The animal in this picture

• ate mostly fish and algae

• moved used a lot of tiny little legs

• lived in an environment that required them to have a hard shell

• had an inner skeleton that helped keep its shape

What has to happen to an organism (plant, animal, or fish) for it to become a fossil?

• It has to remain above the ground.

• It has to be dried out in the sun.

• It must be buried immediately after death.

• It has to be eaten by other animals.

Where are most fossils formed?

• near volcanoes, because the high heat of the lava helps to form fossils

• in glaciers, because fossils are created when an organism is frozen quickly

• in sedimentary rock, because being buried in sediment helps to form fossils

• near earthquakes, because the shaking ground traps organisms to create fossils
