Guanshanichnus glockerichnoides Weber, Hu et Steiner, 2012

Description: Guanshanichnus glockerichnoides is a vertical burrow

system with a circular or subcircular center. Numerous radial,

ray‐shaped, distally tapering and dichotomously branching ribs are

arranged around the central field, forming a star‐shaped structure,

2–7 cm in diameter. The center shafts of the vertical burrow usually

display a more or less cone‐ or tyre‐like structure.
