Images of a model that is also an artistic reconstruction comparable to Sanctacaris in Fig. 4C. A is the front view of a secondary parenchymal unit (left) and B shows the central venular tree that drains it. In the original, colour coding is used to differentiate the primary units of which the whole is composed. This coding is lost in monochrome reproductions (after Teutsch et al. 1999: fig. 4; copyright of J. Wiley & Sons, Inc.).
