Primary synchrotron microtomographic inventory of the gut contents of one Bohemolichas specimen; diet and gut chemistry remain bounded inferences.
Claim ledger
ecology · highSynchrotron microtomography of Bohemolichas incola inventory specimen 8 maps ostracod, hyolith and stylophoran remains through the gut; prey identity is direct fossil content, while feeding rate, selectivity and neutral-to-alkaline chemistry are bounded inferences from one meal.
claim:event:bohemolichas-gut-contentstaxonomy · highThe profiled specimen is referred to Bohemolichas incola, while PBDB treats Bohemolichas as a subjective synonym of Uralichas; the profile preserves that taxonomic caveat.
claim:taxon:bohemolichas:taxonomybiogeography · mediumThe profile is restricted to one Šárka Formation specimen from the Prague Basin and does not define a genus-wide distribution.
claim:taxon:bohemolichas:biogeographyecology · mediumOstracod, hyolith and stylophoran remains directly document one meal; prey selectivity, feeding rate and usual diet remain inferred.
claim:taxon:bohemolichas:ecologymorphology · mediumSynchrotron microtomography maps the alimentary tract and shelly prey remains in inventory specimen 8.
claim:taxon:bohemolichas:morphologyfossil-range · mediumThe 466–463 Ma interval is a formation-level context for the profiled specimen, not a global genus FAD, LAD or continuous duration.
