Carbon Films & Trace fossils Carbon films is element that is found in

every living thing. Trace fossils are foot print of dinosaurs.

Original Remains In original remains are fossils that have actual bodies or

body parts of organism. (ex. Ice, amber, Tar) Ice is one of the best preservers of the remains of

prehistoric life. Amber is a sticky liquid come from wood that makes

preserves of insects. Tar is the living things became oil at long time ago.

Review Questions!

Why many fossils aren’t being igneous rock?

A) Because if they are in igneous rock, they would melt so scientists don’t know what happened on past.

B) Because if they are in igneous rock, they would melt so geologists don’t know what happened on future.

YES,

Because if they are in igneous rock, they would melt so scientists don’t know what happened on past.

The answer is A, Because if they are in igneous rock, they would melt so scientists don’t know what happened on past.
