LACAZINA OEZTEMUERI SİREL 1981 RENAMED AS PSEUDOLACAZINA OEZTEMUERI (SİREL)» FROM THE THANETIAN LIMESTONE (CENTRAL TURKEY)
Abstract
In 1981, Lacazina oeztemueri Sirel was first described and figured by the present author from the Paleocene (Thanetian) of the different regions in central Turkey; Aksaray (southeast of Tuz lake), Kırıkkale (southeast of Ankara), Ereğli (northwest of Bolkar mountains), and Örencik, Demircilik (southeast of Sivas). In this paper, Lacazina oeztemueri is reviewed on well preserwed material of this species. Because of the following characters, Lacazina oeztemueri Sirel is renamed as Pseudolacazina oeztemueri (Sirel); all the chambers of the form A are arranged in biloculine mode; the growth stages of the form B are composed of quinqueloculine with proloculus, biloculine and monoloculine chambers; the septula are arranged in continuous rows in both generations (form A, B).— In 1981, Lacazina oeztemueri Sirel was first described and figured by the present author from the Paleocene (Thanetian) of the different regions in central Turkey; Aksaray (southeast of Tuz lake), Kırıkkale (southeast of Ankara), Ereğli (northwest of Bolkar mountains), and Örencik, Demircilik (southeast of Sivas).
