VERIFY:length_max_m: stored=13 suggested=10 confidence=high — Current descriptions of the holotype (MACN-N 15) consistently give a total length of about 9–10 m for Amargasaurus, with the largest published figures around 10.3 m. A stored maximum of 13 m exceeds every estimate the literature supports.
