Shell patterns, 1978.

"Shell impressions are fascinating due to their natural geometry, often displaying symmetrical patterns or spiral shapes that follow mathematical principles like the logarithmic spiral. These structures are both aesthetically pleasing and scientifically valuable. Fossil shell impressions form when shells are embedded in soft sediment that later hardens into rock, leaving behind detailed imprints of the shell's surface.

They offer insights into the past, helping geologists date rock layers and reconstruct ancient climates and ecosystems. The fine details of the impressions, such as ridges and grooves, reveal information about the shell species and environmental conditions, making them an intriguing window into Earth's history.
