Merlia sp.

Fig. 6L View Fig .

Material.—Upper Eocene, south-central Ukraine.

Remarks. —The small oval, ring-shaped spicule called clavidisc shown on Fig. 6L View Fig can be assigned to one of the species of Merlia . Four recent species of Merlia are distinguished and three of them, M. normani Kirkpatrick, 1908 , M. tenuis Hoshino, 1990 , and M. deficiens Vacelet, 1980 , possess clavidiscs. The spicule that is illustrated here can be assigned to one of these species or its close relatives. It is worth noting that Merlia is characterized by basal calcareous skeleton that was not found in these deposits. Similar calvidiscs, not associated with basal calcareous skeleton, are known since the Early Jurassic ( Wiedenmayer 1994).
