Description. Single specimen from Rakowice
Małe locality, flat fruit of ovoid shape ( Figure 4A View FIGURE 4 ).
Length 1.3 mm; breadth 0.8 mm. Apical part of fruit concave ( Figure 4B View FIGURE 4 ). Persistent perianth fused basally, forming hypanthium. Tepals attached on the top of hypanthium. Tepals not preserved; their insertion indicated by attachment scars, indicating four tepals in two decussate pairs. Lateral face of fruit shows a long concave tepal attachment scar, placed mid-way between the base and the apex. Medial scars small, close to the base. The lateral face of the fruit shows a diamond shaped area. Length of this area 0.9 mm; breadth of fruit 0.7 mm. Epidermis of the fruit composed of small irregular cells ( Figure 4C View FIGURE 4 ).
Remarks. The specimen from the Rakowice Małe locality is slightly longer than other fruits of Caryanthus communis ( Heřmanová et al., 2016) . The species Caryanthus communis is described as having a concave base, but the specimen from Rakowice Małe has slightly pointed base. However, absence of this character may be due to poor preservation of the specimen.
Range. Late Coniacian or early Santonian age.
Occurrence. Rakowice Małe locality.
Material studied. K 2899; the material is housed in the National Museum Prague.
