Mixosaurus kuhnschnyderi ( Brinkmann, 1998b)

Figure 6

Material: Holotype PIMUZ T 1324 ( Fig. 5 ) and a referred specimen housed in Milan ( Brinkmann, 1998a).

Locality: Monte San Giorgio (Tessin, also Italy).

Stratigraphic position: Besano Formation, Middle Triassic, Anisian.

Short description: Two specimens of M. kuhnschnyderi are known, the osteologically immature (sensu Miedema et al., 2023a) and extensively disarticulated holotype, and a larger referred specimen, consisting of an articulated skull preserved and fragmentary postcranium in lateral view ( Brinkmann, 1998a). M. kuhnschnyderi is a small ichthyosaur, less than 1.5 m long. Te skull is similar to M. cornalianus , but conical and rounded crushing teeth alternated in the posterior part of the jaw ( Brinkmann, 1998a, b; McGowan & Motani, 2003).

Remarks: Te species was formerly included in the genus Sangiorgiosaurus Brinkmann, 1998b ( McGowan & Motani, 2003: p. 69).
