Dianchicystis
species of vetulocystids
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.
“Dianchicystis” enters the record as species of vetulocystids. Crown Archives preserves that source wording while asking what Dianchicystis, species and vetulocystids can confirm, complicate or overturn.
Why this record matters
“Dianchicystis” is worth following because a concise public description often conceals a longer documentary argument. Here, Dianchicystis, species and vetulocystids provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 9, 2025. The linked authority identifier is Q108384780. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
