Amplectobeluidae

Amplectobeluidae is a clade of Cambrianradiodonts. It currently includes five definitive genera, Amplectobelua, Lyrarapax, Ramskoeldia, Guanshancaris and a currently unnamed genus from the lower Cambrian aged Sirius Passet site in Greenland. There is also a potential sixth genus, Houcaris, but that genus has become problematic in terms of its taxonomic placement.
