Caryanthus sp.

Figure 4 View FIGURE 4 G-L

Description. The single specimen from the Rakowice Małe locality is a slightly deformed flattened fruit, ellipsoid in shape ( Figure 4G View FIGURE 4 ). Length 1.4 mm; breadth is 2.0 mm. Apical part of the fruit concave and strongly deformed ( Figure 4H View FIGURE 4 ). Basal part convex. Persistent perianth fused basally, forming hypanthium, which covers the entire fruit. Lateral faces of fruit show five slightly sunken ridges running from base to apex, surface covered with irregular thick-walled cells ( Figure 4I View FIGURE 4 ). Distinct compact outer and inner layers of the fruit wall consist of small cells. The middle layer has larger cells ( Figure 4 View FIGURE 4 J-L).

Remarks. Lateral face of Caryanthus trebecensis shows two to four sunken ridges, lateral face of Caryanthus triasseris shows three parallel ribs and lateral face of this fruit shows five slightly sunken ridges so it is difficult to decide to which species this specimen belongs, either to C. trebecensis or C. triasseris .

Range. Late Coniacian or early Santonian age.

Occurrence. Rakowice Małe locality.

Material studied. K 2906; the material is housed in the National Museum Prague.
