The writer of the present paper has studied the fossils collected in 1966 by O. Kaya from
Cebeciköy and Belgrad Forest of the Istanbul region (Fig. 1). Results obtained show that two of the specimens characterize
Whidbornella caper at a (Sow.) and that the stratigraphical level in which they were found is by far different from
those known up-to-date.
In European literature reference is made to this specimen which was encountered in the transition zone between
Upper Devonian and Lower Carboniferous strata as well as in the Etroeungt beds. In Turkey, however, this specimen was
encountered for the first time in the above-mentioned locality in the upper levels of the Middle Visean and the middle
levels of the Upper Visean.

1966 yılında O. Kaya
tarafından İstanbul yöresinde Belgrad ormanı ve Cebeciköy'den toplanmış fosil
koleksiyonu üzerinde yazar tarafından çalışmalar yapılmıştır (Şek. 1).
İncelemeler sonucunda, numunelerden iki tanesinin Whidbornella caperata
(Sow.)'yı karakterize ettiği görülmüş olup, işaret ettiği stratigrafik
seviyenin de şimdiye kadar bilinenden daha değişik olduğu saptanmıştır. Avrupa
literatüründe, Üst Devoniyen-Alt Karbonifer geçişi ve Etroeungt tabakalarında
bulunduğu bilinen bu numune, ilk defa Türkiye'de yukarıda bahsedilen lokalitede
Orta Vizeyen üst kısmı ile Üst Vizeyenin orta seviyeleri arasında bulunmuştur.
