Scientists discovered the 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.

by studying their fossils
by reading about them
by watching movies

What must happen to an organism's body for it to become a fossil?
It must remain above ground.
It must dry out in the sunlight.
It must be buried right after death.
It must 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

long ago, mostly by studying fossils?
biologist
zoologist
botanist
paleontologist
