Abstract

Fossil remains of turtles from the Kudinovka locality (Paleogene, Paleocene or Ypresian; Millerovo District, Rostov Province, Russia) are described. These remains, represented by 16 specimens, are referred to the sea turtle Tasbacka aldabergeni Nessov, 1987 (Cheloniidae), previously reliably known only from the Zhylga 1 type locality (Paleogene, Late Thanetian–Early Ypresian; southern Kazakhstan). One of the described specimens includes most of the postcranial skeleton in a phosphate nodule and appears to be the most complete postcranial specimen of Tasbacka aldabergeni, which provides previously unknown details of the morphology of this species. The new materials expand our knowledge of the geographical distribution of Tasbacka aldabergeni and the genus Tasbacka in general.
