Halwaxiida or halwaxiids is a proposed clade equivalent to the older orders Sachitida He 1980[2] and Thambetolepidea Jell 1981,[3] loosely uniting scale-bearing Cambrian animals, which may lie in the stem group to molluscs or lophotrochozoa. Some palaeontologists question the validity of the Halwaxiida clade.[4]
