Dianchicystis is an extinct genus of vetulocystid deuterostome. It was found in Jianshan, China, near Haikou, in the Cambrian Qiongzhusi Formation.[1]
Etymology
Jianshan is to the locality from which the four initial specimens were collected, and "Dianchi" comes from nearby Dianchi lake.[2]
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.[2]
