VERIFY:weight_max_kg: stored=2700 suggested=1700 confidence=medium — The peer-reviewed review of Baryonyx puts the holotype (a possibly not fully grown individual) at roughly 1.2–1.7 t, and the highest published mass estimate for the taxon in the technical literature is about 1,980 kg (Therrien & Henderson 2007). A stored maximum of 2,700 kg is materially above the range current sources support; the stored minimum of 1,200 kg, the 7.5–10 m length range, the ~130–125 Ma Barremian Weald Clay dating and the European-only occurrence all check out.
