Fig. 9 in The Late Pleistocene mollusk fauna of Selitrennoye (Astrakhan province, Russia): A natural baseline for endemic Caspian Sea faunas

Fig. 9. Shelly residue from the Caspian Sea floor on the North-Middle Caspian Basin transition offshore Kazakhstan (44°43.4 N, 50°13.2 E; water depth 8 m). The soft bottom fauna is dominated by Holocene invasives such as (1) Abra segmentum, (2) Cerastoderma spec. Asensu Wesselingh et al. (2019), and (3) Mytilaster minimus. Pontocaspian endemics occur in this sample: (4) Monodacna albida s.l., (5) Didacna spp., (6) Dreissena caspia and (7) Turricaspia meneghiniana, yet these all are discolored and presumably pre-20th century).
