Chaetognaths are Deuterostomia, aren't they? I wouldn't know of any doubt about that.
- Recent studies have shown that they are in fact Protostomia

Are the lophotrochozoa and ecdysozoa clades/divisions for protostomia not included for a reason?
Is Dinocarida a class or a phylum? It is currently being treated as a class of the phylum 'Problematica' and a phylum in its own right. Also,is Dinocarida a sort of catch-all for Cambrian invertebrates that don't have known living relatives?
