( Fig. 8 D-F)

Cellaria denticulata Lamarck, 1816: 137 .

Crisia denticulata – Vávra 1975: 523, pl. 1, fig. 1. — Hayward & Ryland 1985: 54, fig. 16. — Poluzzi et al. 1988: 64, figs 15b-d. — Poluzzi & Rosso 1988: 99, pl. 1, fig. 1. — Zabala & Maluquer 1988: 165, text-figs 480-482, pl. 29B. — Bobies 1958: 153, pl. 13, figs 5-7. — Marcopoulou-Diacantoni & Wuest 1999: 552, pl. 2, fig. 6.

OCCURRENCE. — Middle Miocene: Austria, Hungary, Czech Republic ( Bobies 1958; Vávra 1975). Late Miocene: Sardinia, Sicily ( Moissette et al. 2002). Pliocene: UK, Netherlands ( Lagaaij 1952), Belgium, Crete (Marcopoulou-Diacantoni & Wuest 1999). Pleistocene: Sicily ( Rosso 1987). Recent: western and eastern Atlantic ( Canada to Gulf of Mexico, Madeira, Azores, Norway to Ghana), Mediterranean. This species lives at depths between 0 and 100 m, but it is associated with deep-water-corals in Norway (Sula Reef: 275-295 m; Mortensen & Fosså 2006) and in the Bay of Biscay ( Calvet 1896).

REMARKS

C. denticulata closely resembles the fossil species C. hoernesi Reuss , which however has a greater number of zooids per internode (14-16).
