The Westerstetten pattern is a geological structure in sedimentary rock with an unexplained origin. The name is based on the location Westerstetten on the Swabian Alb north of Ulm .

At Westerstetten, limestones were found in tertiary , clay-filled karst crevices of the Weißjura there , which are covered by a fine-grain, several centimeter-thick limestone crust, which has an unusually regular, spiral-ring-shaped structure. So far, it is not clear how it originated, but it is assumed that it is not of biological origin ( biogenic ), i.e. that no living beings were involved in its formation. For example, there is an exhibit in front of the museum at the Löwentor in Stuttgart .
