Tatrasuchus

Tatrasuchus is an extinct genus of temnospondyl from the Middle Triassic of Poland and Germany. It is classified as a member of the family Cyclotosauridae or Mastodonsauridae. It is closely related to the genus Cyclotosaurus. The type species, Tatrasuchus kulczyckii, was named in 1996. Damiani (2001) considered genus Kupferzellia Schoch (1997) from the Middle Triassic of Germany to be a junior synonym of Tatrasuchus, and recombined its type species, K. wildi as the second species of Tatrasuchus. This classification was followed by some authors, e.g. Fortuny et al. (2011); other authors, e.g. Schoch (2008), maintain Tatrasuchus and Kupferzellia as distinct genera. However, Schoch & Moreno (2024) synonymized the two genera, maintaining T. wildi as a distinct species from T. kulczyckii.
