Figure 3.
Species distribution (A), carapace/valve percentage values (B), Simpson's index values (C) and amount of fragmented/crushed carapaces (D). Missing values in the carapace/valve ratio indicate either a barren sample or one with less than five individuals. "Unknown" refers to ostracodes whose genera or species could not be identified due to poor preservation of the specimens.

Figure 8.
Data integration of Carbomil Well. Figured ostracodes are Fossocytheridea sp. 1, Perissocytheridea sp. 1, Bairdoppilata sp. 2 and Cytherella mediatlasica. Crosshatched bar in the Carapace/Valve ratio column indicates number of carapaces, while the light grey bar shows the amount of valves.
