| "And Mar Rav Tzemach bar Mar Rav Kafnai reigned two and a half years, and he died at the beginning of the year 1249" (938 CE). | tradition | ★★★★☆ | |
| No source names his teacher. Per this atlas's succession roster, Rav Kimoi bar Achai and Rav Hai bar David held the headship of his academy during his formative window (c. 4645–4665 AM), making reception from them the likeliest reconstruction.
Derived by era-and-institution inference, not attested. The formative window is computed from this entry's schematic dates, hence the low confidence.
