Lepidorhombus circularis was a flatfish relative known in the London Clay from sagittal otoliths. Its placement with scophthalmid-grade flatfishes implies a bottom-associated adult lifestyle, with the body lying on one side and the eyes displaced to the upper surface. Those body features are not preserved in the London Clay material itself, so the ecological reconstruction comes from phylogenetic comparison rather than direct anatomy.

The otolith is small, thin and unusually rounded, with a straight narrow sulcus and a strong depression surrounding it. It provides evidence that specialised flatfish lineages were already part of the Ypresian marine fauna even where their fragile skeletons have not survived.
