Abstract From the early Cambrian of Yunnan, China, new chancellorid scleritomes assigned to Allonnia junyuani new species are described and compared with scleritomes of Chancelloria eros Walcott, 1920 from the Middle Cambrian of Utah, USA and isolated phosphatized chancellorid sclerites from the Georgina Basin of North Australia. Characters of the entirely preserved chancellorids offer new insight into the paleobiology of Chancelloridae. An irregular thickening at the inferred base of the… 

New well-preserved scleritomes of Chancelloriida from early Cambrian Guanshan Biota, eastern Yunnan, China

Abstract A large number of well-preserved chancelloriid scleritomes from the Guanshan biota, early Cambrian of Yunnan, China, are described as a new species, Allonnia tenuis n. sp., and provide solid

Chancelloriid sclerites from the Lower Cambrian (Meishucunian) of eastern Yunnan, China, and the early history of the group

TLDR
Large samples of chancelloriid sclerites from the Meishucunian (pre-trilobitic Lower Cambrian) of eastern Yunnan Province, China are reported on, finding that Chancelloriella irregularis is characteristic of rocks of the Paragloborilus subglobosus – Purella squamulosa Assemblage Zone and the Watsonella crosbyi Assemblies Zone.

Naked chancelloriids from the lower Cambrian of China show evidence for sponge-type growth

TLDR
It is possible to interpret chancelloriids as sponges with an unusually robust outer epithelium, strict developmental control of body axis formation, distinctive spicule-like structures and, by implication, minute ostia too small to be resolved in fossils, which may contribute to the emerging picture of high disparity among early spongees.

Chancelloriid sclerites from the Dyeran–Delamaran (‘Lower–Middle’ Cambrian) boundary interval of the Pioche–Caliente region, Nevada, USA

Chancelloriids are a poorly understood group of phylogenetically problematic Cambrian metazoans; complete specimens show they were sessile, radially symmetrical, club‐shaped organisms covered with

Chancelloriid Allonnia erjiensis sp. nov. from the Chengjiang Lagerstätte of South China

TLDR
Overall features of Al. erjiensis indicate that the sclerite density needs to be considered when distinguishing the chancelloriid species, and reveal that sclerites with different ray shapes may be present in the same scleritome, which provides new quotable information to study and classify the isolated chancellORs from the shelly faunas.

CHANCELLORIID SCLERITES FROM THE DYERAN–DELAMARAN (“LOWER”–“MIDDLE” CAMBRIAN) BOUNDARY INTERVAL OF THE PIOCHE–CALIENTE REGION, NEVADA, USA

A new chancelloriid from the Emu Bay Shale (Cambrian Stage 4) of South Australia

Chancelloria australilonga sp. nov. is described from the Emu Bay Shale (Cambrian Series 2, Stage 4) of Kangaroo Island, South Australia. The new species has a typical sac-like body, equipped with a

TLDR
During the course of the study on the early skeletal fossils collected from th e Maidiping Formation, a lot of star shaped chancelloriid sclerites were found, and the concept of the Coeloscleritophora is still adopted here.

The cap‐shaped Cambrian fossil Maikhanella and the relationship between coeloscleritophorans and molluscs

TLDR
Maikhanella shells were formed through the embedding of spicules in secondary calcareous shell zubstance, and together with the polyplacophoran-like features of the Halkieria scleritome this forces a reconsideration of the phylogenetic relationships between coeloscleritophorans and molluscs.

A reassessment of the enigmatic Burgess Shale fossil Wiwaxia corrugata (Matthew) and its relationship to the polychaete Canadia spinosa Walcott

TLDR
Anatomical and histological comparison with modern organisms indicates that Wiwaxia sclerites are polychaete paleae (flattened setae) and that WiWaxia was a jawed annelid broadly related to the extantpolychaete families Chrysopetalidae and/or Aprhoditidae (Palmyra).
