Extract
Blastozoan echinoderms include several classes of stalked echinoderms with a combined stratigraphic range from Lower Cambrian to Upper Permian. Ranges of constituent classes tend to be much shorter, except for the Blastoidea, which are known from the Middle Ordovician (Broadhead, 1980) to the Upper Permian (Breimer & Macurda, 1972).
