2004 Gnathophis saubriguensis ( Steurbaut, 1979) – Nolf and Brzobohaty, pl. 1, fig. 3–5

Material

Fifteen specimens from level 11 and three specimens from level 12.

Distribution

Aquitanian of the Aquitaine Basin (SW France; Steurbaut, 1979, 1984) and the MHB, and Burdigalian of northern Italy ( Nolf and Brzobohaty, 2004).

Remarks

The orientation of the sulcus relative to the posterior–anterior axis is angular, with an 11–24 ◦ angle. The anterior edge shows the same opening feature as the specimens from the late Burdigalian of Piedmont, Italy ( Nolf and Brzobohaty, 2004). The distal–ventral angle is pointed, as in the specimens figured from the late Oligocene–lower Miocene of France ( Steurbaut, 1984).
