5 mm (0.20 in) in diameter located slightly eccentrically towards one of the ends of the fossil. One of the aforementioned ends being more elongated, with the other end being more rounded in nature. The latter of the ends shows a short, protruding neck that becomes wider when reaching its termination. With the termination that ends the neck being rather unevenly lobate, with the terminations margins being sharp and even in appearance. The structures surface is generally smooth, except for the local grain-sized corrugations, the thin and short grooves and a longer, narrower groove that runs obliquely throughout three-quarters of the width that is closer to the wider end of the holotype's body.

concentric rings around the terminations. These concentric rings are more continuous on one side than the opposite side, where on the latter only fragments of them are visible instead of the full ring. This structure also shows a multitude of small corrugations, although these corrugations do not form any pattern whatsoever. The edges of the structure are remarkably either elevated or depressed and more often than not show a double ridge which is 1.5β3 mm (0.059β0.118 in).

Smaller specimens of this species can be present without the protruding neck as well as the other multiple protrusions/depressions within the fossils.
