Apparatus compositions of Guizhoudella triangularis.

Diagnoza

Elements with thin walls of the very deep basal cone, strongly curved cusps; sharp, numerous denticles.

Porównanie

The holotype of the type species represents an S₁ element. S_3-4 elements from the same sample were named Belodella bilinearis. This is so bizarre a conodont that identification of its elements does not cause any difficulties, even if they are very rare in samples. Some specimens resemble P elements of typical prioniodinids but variability is so wide that recognition of discrete element types may not be possible.
