Palaeoscolecid scleritome fragments with 'Hadimopanella' plates from the early Cambrian of South Australia
Phosphatized articulated palaeoscolecid scleritome fragments with attached 'Hadimopanella' Gedik, 1977 plates are described from the lower Cambrian Mernmerna Formation of South Australia. 'Hadimopanella' is principally known from single, isolated, button-shaped, phosphatic scleri...
