Louisella is a genus of priapulid worm known from the Middle Cambrian Burgess Shale. It was originally described by Charles Walcott in 1911 as a holothurian enchinoderm,[1] and represents a senior synonym of Miskoia, which was originally described as an annelid.[2] 48 specimens of Louisella are known from the Greater Phyllopod bed, where they comprise < 0.1% of the community.[3] It has palaeoscolecid-like sclerites.[4]
