Saurosphargis is an

saurosphargid, known from the Middle Triassic (Anisian age) of southwestern Poland and eastern Netherlands. It contains a single species, Saurosphargis volzi.[1][2]

Discovery

Saurosphargis is known solely from the unnumbered

saurosphargid species, that enabled better comparisons with the detailed descriptions and figures of Saurosphargis in Huene (1936).[2]

Paul Albers and Li et al. (2011) briefly reported the discovery of well-preserved material referable to Saurosphargis from the Lower Muschelkalk of Winterswijk, Netherlands. The material is currently under preparation.[2]

Etymology

Saurosphargis was officially named by

leatherback turtle, in reference to the dorsal osteoderm "body armor" and broadened ribs forming a closed chest rib basket, traits that are seemingly transitional between turtles and other reptiles. The specific name volzi honors the paleontologist Wilhelm Volz who found and briefly described the holotype of Saurosphargis and the Lower Muschelkalk of Gogolin between 1903 and 1908.[1][3]
