VERIFY:period_end_mya: stored=155 suggested=160 confidence=medium — The Anchiornis-bearing beds of the Tiaojishan Formation (Yaolugou/Jianchang, Liaoning) are dated to roughly 160.9–160.3 Ma, i.e. earliest Oxfordian, so a range ending at 155 Ma extends about five million years past the youngest supported fossil horizon and into the Kimmeridgian, conflicting with the stored Oxfordian stage. The stored start value of 161 Ma is consistent with these dates and is not flagged.
