Spinosauridae is represented by Hone and Holtz’s revision of named and fragmentary material; subfamily assignments and ecological signals are evidence-weighted hypotheses, not a complete family range or uniform semiaquatic ecology. This navigation entry is not a phylogeny or a complete taxon dossier.
Automated checks cover structure, identifiers, translations and links only; maintainer and external expert review are not complete.
