Geological Chronicle

Located in the rugged terrain of the Moon's southern hemisphere, Wurzelbauer is the remnant of a lunar impact crater measuring 86.77 kilometers in diameter. The slightly smaller crater Gauricus lies next to its eastern rim, while Pitatus is to the north-northeast. The feature is named after German astronomer Johann Philipp von Wurzelbauer.

The rim of the crater has been deeply eroded, forming a low, somewhat irregular ridge around the interior floor. A short chain of craters lies across the northern rim. Along the southeastern rim is Wurzelbauer B, while Wurzelbauer A is nearly attached to the southern rim.

The western half of the interior floor is somewhat more irregular than the east, with a complex of low ridges covering parts of the surface. The western edge of the floor is marked by a section of the ray system radiating from Tycho to the south-southeast.
