The tar is often covered with dust, leaves, or water. by John D. Morris, Ph.D., and Tim Clarey, Ph.D. * Modern college textbooks still maintain that the famous Rancho La Brea tar pits in southern California are evidence of sticky, tar-like material (bitumen) trapping and engulfing animals slowly over time.1 An alternative explanation contends that the collection of fossils is the result of catastrophic water transported by episodic flooding Sometimes they seep from the ground and create large puddles known as tar pits or asphalt lakes.
