Leanchoilia superlata (type) |
|
Leanchoilia is a four-eyed arachnomorph arthropod known from the Cambrian Burgess shale. It was about 5cm long and had long, whip-like feelers mounted on frontal arm-like appendages. Its guts are sometimes preserved in three dimensions.[1]
Leancholia is found in the Burgess Shale in Canada.
Two species are tentatively accepted today: the type species L. superlata and the recently-revalidated L. persephone. They may however be examples of sexual dimorphism.[2]55 specimens of Leanchoilia are known from the Greater Phyllopod bed, where they comprise 0.1% of the community.[3]
