In referance to the "paleontolgists are stumped" comment, paleontologists arent realy stumped, they just havent approached it properly, I am one so I would know that, currently I've made a paper linking Tullimonstrum to Amiskwia Planus, a cambrian free swimming animal that appears to have molluskan affinity, but by linking it to the recently discovered vetustovermis planus, I think it belongs in a stem leniage between protostomia and protoarthropoda, as I believe it is part of the soft bodied liniage that spawned some of the protoarthropoid preditors of the Cambrian, and I also feel this should be the area that soft bodied arthropod like animals from the precambrian like spriggina, and dicksonia which obviously could be soft bodied arthropoid ancestors. for instance, Spriggina:

It's my beliefe that Spriggina gave way to at least 2 different types of ancestors, one of which became Naraoia and their kin (which were eventualy the trilobites): http://www.hrw.com/science/si-science/biology/animals/burgess/img/fnara.gif
the other being the ancestral creature that led to Marrella: http://www.hrw.com/science/si-science/biology/animals/burgess/img/fmarella.gif
It is my beliefe that this group links arthropoda and proto arthropoda, that is, it is the home of the soft bodied prototypes to both groups. with amiskwia leading to the anamalocarids as well as vetustovermis and tullimonstrum. with spriggina leading to myriapoda, checlerata, and crustacia. It is however possible that myriapoda may be related to the protoarthropod anamalocaris based on Kerygmachela. But I don't think that is likely. - BURK
