VERIFY:length_max_m: stored=1.3 suggested=1 confidence=medium — Sources compiling the holotype material (IGCAGS V371, a partial skull and fragmentary skeleton) give an estimated maximum length of about 1 m, and describe the animal as 'at less than one metre long'; Paul (2010) likewise estimated roughly 1 m (3.3 ft), so a 1.3 m upper bound is not supported.

VERIFY:weight_max_kg: stored=20 suggested=8 confidence=medium — Published mass estimates for Chaoyangsaurus cluster at the low end: Paul (2010) estimated about 6 kg (13.2 lb) and compilations of the holotype give an estimated maximum of about 8 kg, so a 20 kg upper bound is roughly triple the supported figure.
