VERIFY:weight_min_kg: stored=400 suggested=1000 confidence=high — The Natural History Museum's Dino Directory gives a mass estimate of roughly 1,000-2,000 kg for Aardonyx, based on comparison with similar sauropodomorphs; the stored 400 kg lower bound is far below any published estimate.

VERIFY:weight_max_kg: stored=600 suggested=2000 confidence=high — Current estimates place the upper mass of Aardonyx at about 2,000 kg (other compilations cite ~1.7 tonnes), more than three times the stored 600 kg maximum.

VERIFY:length_max_m: stored=7 suggested=10 confidence=medium — The two known specimens were roughly seven metres long but were immature (under about 10 years old and still growing), so a full-grown adult is estimated at around 10 metres or more; other compilations cite maxima of 8.7-9 m.

VERIFY:period_start_mya: stored=199.3 suggested=201.3 confidence=medium — Radiometric and detrital-zircon dating supports a Hettangian-Sinemurian age for the upper Elliot Formation, which hosts Aardonyx; the base of the Hettangian is ~201.3 Ma, so the stored 199.3 Ma start (an outdated Sinemurian base) is inconsistent with the stored Hettangian stage assignment.
