VERIFY:period_end_mya: stored=74 suggested=75 confidence=medium — Current literature constrains S. validum material to the Belly River Group, where specimens come from the Oldman Formation (middle Campanian, 77.5-76.5 mya) and the Dinosaur Park Formation (late Campanian, 76.5-75 mya), so the youngest confirmed occurrence is about 75 mya rather than 74 mya. The stored start value of 77.5 mya matches the Oldman Formation base and is supported.
