Odontogriphus 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:taxonomyOdontogriphus omalus
A 189-specimen sample repeatedly preserves transverse tooth rows, a broad foot and mantle-groove structures; radular homology remains an interpretation.
Represented range508–505 Ma
Content packagemolluscs-brachiopods

Evidence boundary
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
Claim ledger
The 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.
claim:taxon:odontogriphus:fossil-rangeKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
