Tar pits, sometimes referred to as asphalt pits, are large asphalt deposits. They form in the presence of petroleum, which is created when decayed organic matter is subjected to pressure underground. If this crude oil seeps upward via fractures, conduits, or porous sedimentary rock layers, it may pool up at the surface. [1] .

The La Brea Tar Pits is an active paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural asphalt (also called asphaltum, bitumen, or pitch; brea in Spanish) has seeped up from the ground for tens of thousands of years.
Asphaltic deposits or "tar pits" present a unique opportunity to study past ecosystems because they preserve many different kinds of fossils (and lots of them!). Tar pits are especially important for scientists in areas where fossils don't normally preserve well, such as the Neotropics.

The Tar Pits provide an incredibly complete record of the different plants and animals that have lived in the L.A. Basin between 50,000 years ago and today. We research and exhibit huge, extinct mammals such as saber-toothed cats, dire wolves, and mammoths, as well as “microfossils”—the tiny remains of plants and animals that can give us ...
A sculpted mammoth shows visitors to the La Brea Tar Pits what these ancient animals might have looked like, but the pits themselves have looked the same for thousands of years. How did they form, and what discoveries lie beneath the sticky surface?
