Unit 2 Fossils

Scientist discovered fossilized remains of an unidentified 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 mammal.
• It lived in the water all the time. 
• It had legs that did not fossilize.
• It lived in the water and on land.

How did scientists first learn about dinosaurs?

• by studying their fossils
• by reading about them 
• by watching movies
• by looking at pictures

Garrett and Kristin are paleontologists working on a dig. They carefully uncover an area that looks to have belonged in an ancient forest. They find eggshells, bones, nests, teeth, claws, and footprints. Garrett is more interested in body fossils, and Kristin is more interested in trace fossils. 
What statement best explains which fossils each paleontologists should take to study?

• Garrett should take the bones, claws, and teeth; while Kristin should take the eggshells, nests, and footprints. 
• Garrett should the claws, eggshells, and nests; while Kristin should take the bones, teeth, and footprints.
• Garrett should take the bones, eggshells, and footprints; while Kristing should take the claws, nests, and teeth. 
• Garrett should take the eggshells, nests, and footprints; while Kristin should take the bones, claws, and teeth. 

Which of the following is NOT a body fossil?

• bones
