The Bay Area through Time

An expedition through Bay Area prehistory

This new picture book takes readers on a one-of-a-kind tour of the Bay Area. Each turn of the page ventures further and further back in time: from a mere three hundred years ago, not long after the arrival of the first European explorers, to when Columbian mammoths lumbered about waterfall-ringed meadows (40,000 years ago); to when saber-toothed cats pounced on three-toed horses (10 million years ago); to when dinosaurs foraged for food on golden, sandy beaches (80 million years ago); and finally to 400 million years ago, when today’s San Francisco Bay was a watery realm dominated by bizarre invertebrates. Fun and fastidiously researched facts about each era’s animals and plants enhance the full-color spreads by A State of Change artist Laura Cunningham. After finishing The Bay Area through Time, readers of all ages will wonder which form the bay will take next.
