Claim ledger
The Barschichthys ruedersdorfensis type and referred specimens come from the Rüdersdorf opencast mine in the Central European (Germanic) Basin, Germany; no global distribution is inferred.
claim:taxon:barschichthys-ruedersdorfensis:biogeographyBarschichthys ruedersdorfensis is recorded from the study's marine restricted-basin setting, but its species-specific diet, locomotor performance and trophic guild remain unresolved.
claim:taxon:barschichthys-ruedersdorfensis:ecologyBarschichthys ruedersdorfensis has a broad lobated skull-roof margin lacking the triangular nasal region, a fused ornamented cranial plate, ganoid scales and a long lower jaw with small conical teeth.
claim:taxon:barschichthys-ruedersdorfensis:morphologyThe displayed approximately 244 Ma point bounds the lower Anisian Rüdersdorf sample of Barschichthys ruedersdorfensis and is not a global teleost first appearance.
