Fossils TN 5th Grade 2018/19 Science Standards

Kyle found a rock and used a hammer to split it open. One half of the rock had a raised shape of a shell. The other had an impression of the shell. What type of fossil did Kyle find?

• a shell preserved in amber

• a mold and cast of a shell

• a shell frozen in rock

• a trace fossil of a seashell

Look at the figure. The Green River Formation in Wyoming is made of layers of rock that contain fabulous fish fossils. The figure you see shows the type of fossils that are found in these rocks. What most likely occurred to allow the fish to be preserved so well?

• Animals ate the fish so the bones were clean and ready to turn to fossils

• The fish got buried in sediment

• The fish moved along until it landed in a safe place

• The temperature increased until conditions were right to form fossils
