How did the La Brea Tar Pits form?

La Brea Tar Pits

These oil deposits were formed during the Miocene Epoch when marine plankton organisms accumulated in an ocean basin. Over time, sediments buried the organisms 300 to 1000 meters below Earth's surface, subjecting them to high pressures. This process turned the organic matter into oil.

What scientist studies fossils?

Paleontologists use fossil remains to understand different aspects of extinct and living organisms. Individual fossils may contain information about an organism's life and environment.

Why do tar pits preserve fossils?

The key thing about preservation is lack of oxygen. Oxygen is a very active chemical and it will break down organic materials. So when the large mammals and other Pleistocene animals fell into the tar pits and sank, they were located in an environment that lacked oxygen. Hence, they were preserved.
