Question 6

6.

Imagine that a student found a fossil of the leaf, shown below, in your school’s playground.

Which conclusion best represents the origin of the fossil based on the evidence shown?

The leaf made an imprint in the sediment before it hardened to rock.

The plants at this time had bones which allowed them to be fossilized.

The leaf was in the fossilized stomach of an animal.

Question 7

7.

Scientists have uncovered palm plant fossils in Alaska, the northern-most state of the United States. Modern-day palm plants grow in tropical climates. A picture of a palm fossil that measures almost one meter across is shown.

This discovery suggests to scientists that this area in Alaska once was —

covered with an ocean

warmer than it is now

populated by polar bears

changed by earthquakes

Question 8

8.

Scientists believe that Texas’s landscape and climate has changed throughout history. 250 million years ago, Texas was believed to be partially covered by salt water. Which of these fossils could be evidence of the fact that there was an ocean where Texas is today?

Select TWO answers.

A bone from a Pleurocoelus, which was a dinosaur that was an herbivore

A shell from an Ammonite, which was an animal related to modern squids

A tusk from a Mastadon, which was an animal related to modern elephants

A piece of petrified Palmwood, which was part of an ancient palm tree

A tooth from a Megalodon, which was an animal related to modern sharks
