Novel evidence for the youngest Naraoia and a reassessment of naraoiid paleobiogeography [PDF]
Naraoiids are nektaspidid arthropods that display two exoskeletal shields, typically lack thoracic tergites, and have an exceptional Cambrian diversity. Despite their predominantly Cambrian fossil record, Naraoia species have been documented in deposits ...
