New data on trematosauroid labyrinthodonts of Eastern Europe: 4. Genus Benthosuchus Efremov, 1937

Abstract

The trematosauroid genus Benthosuchus Efremov, 1937 is revised and its diagnosis is emended. This genus includes the previously established B. sushkini, B. korobkovi, and B. bashkiricus, and the new species B. gusevae described here. The new form is archaic relative to congeners and is similar in a number of characters to the archaic capitosaurid Wetlugasaurus samarensis, which confirms direct affinity of the two genera. © 2012 Pleiades Publishing, Ltd.
