Examine Earth's History With This Geologic Time Spiral
This cool graphic comes from the U.S. Geological Survey and was designed by Joseph Graham, William Newman, and John Stacy. Formatted into a creative spiral shape, you can see how life has progressed since Earth's humble beginning, roughly 4.5 billion years ago. The infographic is split up for each time period and shows both land and sea life.
For more information, see the USGS fact sheet.
