Selkirkia
Scientific classification

Selkirkia is a genus of predatory priapulid worm known from the Middle Cambrian Burgess Shale. 142 specimens of Selkirkia are known from the Greater Phyllopod bed, where they comprise 0.27% of the community. In the Burgess Shale, 20% of the tapering, organic-walled tubes are preserved with the worm inside them, whereas the other 80% are empty (or sometimes occupied by one or more small agnostid trilobites). Whilst alive, the tubes were probably vertical, whereas trilobite-occupied tubes are horizontal. Members Cambrorhytium were originally described as Selkirkia before their identification as a separate genus.

They even appeared in other Shales like Wheeler and Emu Bay and first appeared in the Chengjiang.

They are even shaped like cones.
