| Fasciculus vesanus |
Fasciculus vesanus is an extinct species of ctenophore, known from the Canadian Burgess Shale of British Columbia. It is about 510 to 515 million years old and belongs to middle Cambrian strata.
The species is remarkable for its two sets of long and short comb rows, not seen in similar form elsewhere in the fossil record or among modern species.
Two further fossil ctenophores from the Cambrian are Ctenorhabdotus capulus and Xanioascus canadensis.
