  "abstract": "Morphological phylogenetic matrices are frequently expanded by reusing, modifying, splitting, or combining characters from earlier studies, which complicates comparisons based only on published character numbers. MacronariaMatrix v1.0.0 is a curated cross-matrix resource linking character occurrences among eight selected macronarian and titanosauriform sauropod matrices published from 2009 to 2026, with the 234-character Wilson (2002) matrix retained as a historical reference layer. The frozen release contains 855 active canonical character concepts, 2,377 character occurrences in the eight analysed matrices, 234 reference-layer occurrences, explicit relationship records for modified, split, merged, decomposed, and related character formulations, and a permanent ledger of 87 canonical-ID redirects. Each active concept has an anatomical-region assignment, and all occurrence and redirect identifiers pass release-level integrity checks. The resource supports reproducible comparison of character definitions, provenance, persistence, and reformulation while preserving source wording and numbering.",
