Distinguish between the fossils of ice age mammals found in the La Brea Tar Pits and the organisms that make up the fossil fuels of the tar.

Answer:

The Ice Age mammal fossils are the preserved remains of animals that became trapped in the tar tens of thousands of years ago. The tar itself comes from petroleum formed much earlier, mainly from the buried remains of tiny marine organisms such as plankton that were transformed by heat and pressure over millions of years.
