Stacked Oval Layers Diagram - Geology and Structural Illustration #1352262 (License: Personal Use)

This black-and-white line sketch shows three horizontally aligned oval forms stacked vertically, each with irregular, slightly jagged edges suggesting natural or hand-drawn texture. The layers appear connected at narrow constrictions, evoking either fossilized bivalve shells in stratigraphic sequence or simplified representations of sedimentary rock layers. The base rests on a horizontal line, implying a surface or datum plane.

Used in educational materials on geology, paleontology, or biology to illustrate stratification, fossil preservation, or shell anatomy; often appears in textbooks, lecture slides, or museum exhibits targeting students and general audiences seeking foundational science understanding.
