Earth Through Time 2.2

Why is a fossil more likely to form from the body of a frog in the water than a body of a frog on land?

• currents in the water will move the fish

• scavengers in the water will eat the frog

• soft parts of frogs will decay more quickly in water

• sediment in the water will quickly cover the fish
