DNA-based divergence time estimates suggested major changes in the composition of epiphyte lineages of liverworts during the Cretaceous; however, evidence from the fossil record is scarce. We present the first Cretaceous fossil of the liverwort genus Radula in ca. 100 Ma old Burmese amber. Our analyses support origins of most extant subgenera of Radula by the end of the Cretaceous and diversification of their crown groups in the Cenozoic.
