The Pre-Historic Life Folding Rule -5 billion years of history of planet earth
The four-color side of this wooden ruler presents the evolution of life on our planet in detailed pictures. The opposite side provides information like the scientific names or the size of the depicted plants and animals. The succession of the earth historic epochs (in German, English and French) unfolds here. A “snapshot” of Contintal Drift and a timeline delineating each epoch in black type helps the user to comprehend the immense time periods over which life evolved on our planet. The appearance of dinosaurs, when mammals took over, the first insects or flowers, how life left the seas to conquer land: All this is shown on the PRE-HISTORIC LIFE FOLDING RULE.
