Leanchoilia
Leanchoilia is an megacheiran arthropod known from Cambrian deposits of the Burgess Shale in Canada and the Chengjiang biota of China. It was about long and had long, whip-like feelers mounted on frontal arm-like appendages. Its internal organs are occasionally preserved within the substrate in three dimensions.
Three species are tentatively accepted today: the type species L. superlata, L. obesa and the recently revalidated L. persephone. They may however be examples of sexual dimorphism.
