The rules of rabbinic discourse hold that “Tannaim” – sages of the Mishnaic era, ending around 220 CE – are more authoritative than “Amoraim” – post-Mishnaic sages who appear in the Talmud, from around 220 to around 550 CE. Amoraim are not supposed to disagree with Tannaim, unless they can find other Tannaitic support. But today we see that those boundaries are not hard and fast. Rav was one of the first Amoraim, having himself studied in Palestine with Rabbi Judah the Nasi, the editor of the Mishna, before moving to Babylonia. Our page declares that Rav counts as both Tanna and Amora, giving him an interesting status.
