Diagnosis: Relatively large ichnospecies ofOldha-mia, in which probings radiate in a centrifugal se-quence and turn the tips back 1808on the free side tofill the sectors in between, forming a hook-like struc-ture. Instead of a fixed point of central branching,there is a curved spreite-like structure in the center.

Description: Relatively large systems oriented parallelto the bedding plane, in which branches radiate in acentrifugal sequence and turn the tips back 1808on thefree side. A curved spreite-like structure in the centeroccurs rather than a fixed point of branching.
