The whole twelve “hour” clock represents four billion, five hundred million years of Earth history! That is 4,500,000,000 years. Includes: Clock of Eras impressionistic chart, cut-out pieces, and three levels of arrows with descriptions. Instructions: Cut out each piece of the clock and arrow before laminating. Size: 18" x 24"
