Noordelijke zwerfsteenkoralen (12)

A description is given of syringoporids found as Pleistocene erratics from the northern part of the Netherlands. A new morphogenetic interpretation of the syringoporid skeleton is suggested: tubules (modified pores) and so-called fundibular tabulae (which actually consist of series of tabellae) are considered as adaptions to the fructicose morphology of the colony. Lateral increase has been observed.
