The article reports the finds of amphibians from the four upper layers of sediments (nine conditional horizons) in the Medvezhiy Klyk Cave. The material is represented by isolated bones totaling 4,618 specimens. Each bone was determined separately. Eight species of amphibians were found: Salamandrella schrenckii, Bombina orientalis, Bufo sachalinensis, Strauchbufo raddei, Dryophytes japonicus, Pelophylax nigromaculatus, Rana amurensis, and Rana dybowskii . R. dybowskii and B. sachalinensis are the basis of the batrachofaunas. They are present in all horizons and make up the vast majority of remains. The other species appear sporadically in separate horizons. To reconstruct the paleo-environment, the quantitative ratios of the remains of representatives of various ecological groups of species were revealed.
