Discovery of the oldest known Pterygota in the Lower Carboniferous of the Upper Silesian Basin in the Czech Republic (Insecta: Archaeorthoptera)

A crushed forewing part and counterpart from the lowermost Namurian Paskov drill core preserve cross-veins and main-vein branches attributed to Archaeorthoptera at about 324 Ma; the fragment does not date the origin of insect flight or all Pterygota.

The Insecta root display replaces the unsupported 410 Ma value with a 324–0 Ma sampled navigation envelope anchored by the Paskov Archaeorthoptera wing and living insects; it is not the origin of insects or flight.

The Insect flight evidence route navigation entity is source-linked only to the named specimen, dataset and analysis dossiers already cited by its range ledger. Its displayed span is a study-bounded route or sample envelope, not a biological taxon, ancestor sequence, global FAD/LAD or exact origin interval.

Paskov Archaeorthoptera wing is bounded here by a forewing part and counterpart from the Leonard IV horizon in the Paskov Mine drill core, Upper Silesian Basin, Czech Republic; this single fragment is not a global Pterygota range or flight-origin date.
