The doodle depicts the letters of Google in a five-layered soil formation, similar to that present in a geographic book. Steno played a major role in the discovery of rock formations and he also stated the fact that fossils are actually living things preserved by nature. This fact was pivotal for the development of the modern geology. The doodle shows a colourful layered soil with fossils present in the last layer and trees and grass on the topmost layer depicting the top layer of the soil.

The geologist worked on a shark’s teeth that was caught near the town of Livorno led him to the question of how solid objects could come to be found in other solid objects, such as rocks or layers of rock. His catholic beliefs led him to reason that the layers were organised in a time sequence, with the oldest on the bottom and the youngest on the top.

 
This is the first doodle of Google after the New Year’s doodle and it looks quite yummy, hardly like the arrangement of a soil and more as a layered cake with three-dimensional letters in blue, yellow, red and green.
