( Figures 21–25 View Figures 2–31 )

Cells were brown in colour ( Figure 21 View Figures 2–31 ), 28–45 µm long and 28–45 µm wide. Cells showed a characteristic angular outline with flattened hypotheca and angular epitheca with a very small apical horn ( Figure 22 View Figures 2–31 ). Cingulum was median and offset by one cingulum width ( Figure 21 View Figures 2–31 ). Strong thecal plates with circular ridges around the trichocyst pores and ridges along plate boundaries ( Figures 23 and 24 View Figures 2–31 ). The nucleus was U-shaped and lying across the middle of the cell ( Figure 22 View Figures 2–31 ). Cysts were found in the sediment samples examined ( Figure 25 View Figures 2–31 ), and various spine lengths were noted, probably driven by the low salinities in the Caspian, as has been recorded by Mertens et al. (2012). Cultures of Lingulodinium were the most numerous in this study indicating their common occurrence in the sediment as well as ease of culturing.
