Dianchicystis

Dianchicystis is an extinct genus of vetulocystid deuterostome. It was found in Jianshan, China, near Haikou, in the Cambrian Qiongzhusi Formation.

Etymology

Jianshan is to the locality from which the four initial specimens were collected, and "Dianchi" comes from nearby Dianchi lake.

Description

It is disinguished from Vetulicocystis by an anterior cone that has ribs that are not arranged in platelets, as well as a tapering "tail" (posterior section) with oblique striations. The posterior section has weakly developed furrows, possibly indicating segmentation.
