VERIFY:period_start_mya: stored=166.1 suggested=165.3 confidence=high — The ICS updated all Jurassic stage ages to comply with GTS2020: the base of the Callovian was revised from 166.1 ± 1.2 Ma to 165.3 ± 1.1 Ma, so the stored start age reflects a superseded version of the chart.

VERIFY:period_end_mya: stored=163.5 suggested=161.5 confidence=high — In the same GTS2020-aligned revision the base of the Oxfordian (i.e. the top of the Callovian) moved from 163.5 ± 1.0 Ma to 161.5 ± 1.0 Ma, making the stored end age outdated by about 2 million years.
