PREHISTORIC LOS ANGELES Where movie stars strut on the red carpet, bloody-fanged saber-tooth cats once stalked the grasslands. Where sun-worshipers bask on L.A. beaches, dinosaurs fought life and death battles. Los Angeles is the entertainment capital of the world, but in its distant past it was home of enormous Ice Age mammals, ravenous carnivorous dinosaurs and underwater sea monsters the size of a truck. The city emerged from the sea as gigantic tectonic plates clashed and gave birth to the earthquakes that still rock the city. Explore the history of the City of the Angels as it rewinds back in time... ten thousand years... fifty thousand years... 80 million years... to a mysterious and bloody past.
