Abstract
Lake Enspel was a deep lake which developed in a small trachytic caldera or a bims volcano. One of two finds of aquatic palaeobatrachid specimens from Enspel contains a fish prey as stomach content, which is described for the first time. At the critical time, the lake was meromictic, eutrophic, and without an outlet. The rarity of such finds of water-dwelling frogs is possibly due to the lake margin vegetation acting as some kind of taphonomic filter.
