Highlights•In situ analysis of baddeleyite in the Zagami meteorite yields a precise U–Pb age.•The method improves upon traditional geochronology by avoiding common Pb.•The age we obtain agrees with mineral separate ages using other radiogenic systems.•We conclude that the age (182±7 Ma) reflects the crystallization age of Zagami.•Our results support the meteorites having been preferentially ejected from young terrains on Mars.
