Leanchoilia is a megacheiran arthropod known from Cambrian deposits of the Burgess Shale in Canada and the Chengjiang biota of China .[1]
Description
L. superlata was about 5 centimetres (2.0 in) long and had long, whip-like flagellae extending from its great appendages. Its internal organs are occasionally preserved within the substrate in three dimensions.[2][3]
Species
Seven species are tentatively accepted today: L. superlata (the type species), L. persephone and L. protogonia from the Burgess Shale, L. illecebrosa and L. obesa from the Chengjiang biota, ''L. robisoni from Kaili, and L.? hanceyi from the Spence Shale. L. superlata and L. persephone may however be examples of sexual dimorphism.[4][5][6]
Distribution
55 specimens of Leanchoilia are known from the Greater Phyllopod bed, where they comprise 0.1% of the community.[7]
