Articulated Kutorgina chengjiangensis specimens from Chengjiang preserve valves together with an early spirolophe lophophore, digestive tract and pedicle; these associated soft tissues document a sampled brachiopod anatomy, not a complete lineage or direct ancestor.
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
Chengjiang Kutorgina specimens preserve paired valves with lophophore, digestive tract and pedicle anatomy; this formation-scale sample documents one early rhynchonelliformean, not the global origin of brachiopods.
claim:taxon:kutorgina-chengjiangensisZhang et al. establish Kutorgina chengjiangensis from Chengjiang material and describe its articulated brachiopod anatomy; the species-level diagnosis is distinct from any claim that it is a direct brachiopod ancestor.
claim:taxon:kutorgina-chengjiangensis:taxonomyThe Kutorgina chengjiangensis occurrence documented here is restricted to the Chengjiang Lagerstätte in Yunnan, South China; it does not establish the complete geographic range of the species or brachiopods.
claim:taxon:kutorgina-chengjiangensis:biogeographyThe preserved lophophore and pedicle support a suspension-feeding, attached functional interpretation for the sampled Kutorgina chengjiangensis anatomy; feeding behaviour and habitat use remain inferred rather than directly observed.
claim:taxon:kutorgina-chengjiangensis:ecologyThe Kutorgina chengjiangensis material in the Chengjiang Lagerstätte supports a 520–518 Ma Early Cambrian formation-scale study window; this bounded occurrence is not a global brachiopod FAD, LAD or continuous lineage range.
