Vetulicola cuneata, An Enigmatic Fossil from Chengjiang
"Member of Putative New Phylum Vetulicolia"

Description: Description: This unusual fossil is an example of Vetulicola cuneata (also spelled cuneatus), a member of the Vetulicolians, an enigmatic group which some scientists place in their own phylum (Phylum Vetulicolia). They are thought to have been swimmers that either were filter feeders or detritivores. One researcher places them with the Urochordates, giving them strong affinity with the Phylum Chordata. At present, there is no agreement as to their systematic placement. This specimen comes from the Chengjiang Boita, and is thus slightly older than the Burgess Shale Fauna of British Columbia. This one is primarily composed of the distinctive abdomen of this enigmatic taxon.
