What makes a fossil a "true fossil"?

• a true fossil is found in sedimentary rock

• a true fossil is a bone found in sediments

• a true fossil can only be a dinosaur

• a true fossil is anything found in Michigan

What can zircons in igneous rocks tell us?

• We use zircons to determine when dinosaurs died

• Zircons can be used to determine the age of sedimentary rocks

• We can look at the amount of uranium and lead and find out how much time has passed since the zircon formed

• Zircons tell us what kind of rock a fossil is found in.

What is relative dating?

• Relative dating helps us determine which dinosaur is related to other dinosaurs

• Relative dating looks at where a fossil is found in layers to see which is older (deeper) and which is younger (near surface)

• Relative dating looks at how fossils are related to determine how old animals are

• Relative dating tells us the exact time in history when a fossil forms.

Match the following

• forms when magma cools and solidifies

• zircon

• a special mineral forming in volcanoes

• igneous rock

• forms under intense heat and pressure

• metamorphic rock

• shells, poop, and remains of organisms

• marine snow

• layers compacting and cementing together

• sedimentary rock
