Abstract

Furongian (late Cambrian) echinoderms are extremely rare in the fossil record and only two previous reports have been described from the Paibian Stage worldwide. Here, the third occurrence of an echinoderm from the Paibian, and the first ever reported in the Furongian of Britain is presented. It is a primitive pelmatozoan which shows intermediate characteristics between eocrinoids with columnal-bearing stems and primitive glyptocystitid rhombiferans. The palaeobiogeographic affinities of Cambrian echinoderm faunas from Britain, eastern Avalonia, are shown to be with Gondwana.
