Abstract

А skеlеtоn of аn adult individual, included in а соаl slab is described. The layers belong to the Balsha Member of the Gnilyane Formation. Age: Middle to Upper Turolian – to Maeotian-Pontian (МN 11-13). Measurements (mm): skull length - са. 60,0; mandibula length - са. 48,0; humerus length - са. 58,8; tarsometatarsus length - са. 36,0. The tind is rather damaged because of the flattenation and former attempts to bе preserved. More precise taxonomic identitication would bе speculative. The described gull is the second water bird after Phalacrocorax serdicensis Burchak-Abr. & Nikolov, 1984, а species described from the same site and it confirms the presence of large water bodies in the Middle Miocene in this part of the country.
