A 189-specimen Burgess Shale sample documents a serially replaced feeding apparatus interpreted as a molluscan radula together with a broad foot and mantle-groove structures.
The 189-specimen Odontogriphus sample repeatedly preserves paired transverse tooth rows on a membrane with posterior replacement, together with a broad foot and mantle-groove structures; calling this apparatus a molluscan radula is strongly argued but remains a homology interpretation.
claim:event:odontogriphus-radula-sampleOdontogriphus omalus is treated as an interpretation-bounded molluscan-origin dossier; tooth-row homology does not by itself establish crown membership or ancestry.
claim:taxon:odontogriphus:taxonomyThe profile is bounded to the Burgess Shale sample and does not infer a global distribution.
claim:taxon:odontogriphus:biogeographyBenthic crawling and feeding are inferred from the foot and feeding apparatus; actual substrate use, food and behaviour were not observed.
claim:taxon:odontogriphus:ecologyThe 189-specimen sample repeatedly preserves paired transverse tooth rows with posterior replacement, a broad foot and mantle-groove structures.
claim:taxon:odontogriphus:morphologyThe 508–505 Ma envelope is a Burgess Shale sample interval, not a global species range or crown-mollusc calibration.
