Claim ledger
morphology · mediumHolotype AGM I-1 preserves a small, short-snouted ichthyosauromorph with large flippers and dense limb and rib bone; amphibious habits, suction feeding and its phylogenetic position are bounded interpretations rather than observed behaviour or direct ancestry.
claim:event:cartorhynchus-holotype-body-planfossil-range · highCartorhynchus is anchored here only by holotype AGM I-1 from the Lower Triassic Nanlinghu Formation; that named specimen and horizon do not define the genus-wide first or last appearance or an ichthyosauriform origin.
