The extinct Frullania cretacea sp. nov. is described based on a gametophytic plant fragment preserved in Upper Albian amber from Myanmar (Burma). The fragment contains of a portion of a branched shoot with mamillose leaf lobes and campanulate lobules forming watersacs. The Mesozoic species is assumed to be an early representative of the Frullania crown group and tentatively assigned to F. subg. Frullania.
