The
fossils found at La Brea, lived during the climatic global cooling called
the Wisconsinan Ice Age. This ice age produced climatic changes which are
believed to have been a major factor in the extinctions of the large mammals
found as fossils at La Brea. For 30,000 years of fossil record, recorded
at La Brea, life seems to have flourished. The tar pits have recorded an
incredibly large range in diversity of the fossils which existed from 40,000
up to 11,000 years ago.
