Optical Properties

Optical properties consistent with those of Cretarhabdus.

Remarks

Species of Cretarhabdus are constructed of a cretarhabdid pelaga sloping towards a distally arched central area, which is spanned by an axial cross supporting a distal process. The inter-cross area is occupied by lateral bars that delimit pores arranged in two or more complete concentric cycles. The number of pores in the outer cycle is typically 20 or more, a characteristic feature of Cretarhabdus limbicrassus.
