Figure 5. Schematic drawings of inferred disarticulation of Cambrian stalked echinoderms exemplified by ‘S. globus’, in chronological order. (a) Living position of ‘S. globus’ attached to a skeletal bioclast (indicated by a hyolith). (b) ‘S. globus’ with a few broken brachioles lying on the substrate at death. (c) Relatively simultaneous disarticulation of brachioles, theca and holdfast. (d) Isolated thecal plates, which are the most common gogiid and other eocrinoid elements, preserved in the fossil record, during a late stage of decay.
