VERIFY:geological_stage: stored=kimmeridgian suggested=tithonian confidence=high — The Morrison biozonation places <cite index="27-1,27-3">the C. supremus Zone near the top of the upper member of the Morrison Formation, Tithonian in age, above the C. grandis (mid Kimmeridgian) and C. lentus (late Kimmeridgian) zones</cite>. Type material is likewise logged from the <cite index="30-3,30-4">Upper Brushy Basin Member, Tithonian Stage</cite>, so the Kimmeridgian assignment applies to other Camarasaurus species, not C. supremus.

VERIFY:period_start_mya: stored=155 suggested=152 confidence=medium — 155 Ma corresponds to the Kimmeridgian base of the Morrison Formation and to the genus Camarasaurus as a whole, but <cite index="27-1">C. supremus is restricted to a Tithonian zone near the top of the upper Morrison</cite>, and <cite index="29-8">PBDB records for C. supremus give the Tithonian interval (149.2–145 Ma) in the Brushy Basin Member</cite>. A first appearance around 152 Ma or later is better supported than 155 Ma.
