The locality of Aknikov 1 (Czech Republic, MN 3) has yielded the largest diversity of Dimylidae known from a single locality. Four species are recognised in the few dozen recovered fossils: Dimylus aff. paradoxus, Plesiodimylus sp., Chainodus intercedens and Lacrimodon vandermeuleni nov. gen., nov. sp.
The high diversity supports the assumption of a humid palaeoenvironment for Aknikov 1.
