Q: Looking for information about the La Brea Tar Pits.
from Steve K., Louisville, Ohio, U.S.A.; September 17, 2001

A: The La Brea Tar Pits are famous tar pits in Southern California, USA. A tar pit is a pool of gooey asphalt. It is created when crude oil seeps up from deep inside the Earth through a crack, called a fissure. The less dense elements of the crude oil evaporate, leaving asphalt (a very sticky mess). Water pooled on the tar, attracting thirsty animals. As an animal gets stuck in the tar, it probably attracted predators, who also got stuck. The animals' bones, teeth, and other hard parts are well-preserved in this environment (but they turn brown from the asphalt). Tar pits are located around the world. The oldest organism (a wood fragment) found in the La Brea Tar Pit is from 40,000 years ago.
