...JUN-YUAN CHEN; DI-YING HUANG; SHOU-HWA CHUANG Abstract The Lower Cambrian brachiopod Heliomedusa orienta Sun and Hou, 1987a , first identified as a jellyfish, was later described as a craniopsoid brachiopod. A new sample of 1,150 individuals of this brachiopod, measuring 3.1–22.0 mm long, from two...
