Mississippian Goniatitidae and Entogonitidae material documents a family-level distribution and tests a Lazarus-pattern interpretation within Goniatitida; it is not the order's global history.
claim:taxon:goniatitidaGoniatitida
Korn et al. describe an early Late Viséan Moroccan ammonoid assemblage within Goniatitida; the atlas conservatively displays the enclosing Viséan interval, 346.7–330.3 Ma, as a study-sample window rather than an order-wide FAD or LAD. This navigation entry is not a phylogeny or a complete taxon dossier.
