The genus Trigoides is known from fossils from the Chengjiang Lagerstätte.Chen, Luo, Hu, Yin, Jiang, Wu, Li & Chen (2002). Early Cambrian Chengjiang fauna in eastern Yunnan, China. Kunming, China: Yunnan Science & Technology Press. (In Chinese) It is proposed to be a type of ctenophore.Conway-Morris (2006), Phil Trans R Soc B, 361:1069-83Hu, Steiner, Zhu, Erdtmann, Luo, Chen, Weber (2007).
