Neomeris mokragorensis sp. Nov. (Calcareous alga, Dasycladales) from the Cretaceous of Serbia, Montenegro and the Northern calcareous Alps, (Gosau group, Austria)

Abstract

The new species of the genus Neomeris - Neomeris mokragorensis sp. nov. described in this paper from western Serbia originates: from the Albian of Mokra Gora (the succession transgrading on the serpentinite) and from the Turonian of the Skrapež-Kosjerić area (the succession transgrading on the Carboniferous). The presence of this species has been noted in the Turonian of the Kukes and in the Santonian of the Metohija Cretaceous Unit (Mirdita Zone). In the surrounding of Podgorica (Dinaric Carbonate Platform, Montenegro), the same species previously was presented as Neomeris cf cretacea STEINMANN. Well preserved Neomeris specimens from the Turonian to the Santonian strata of the Northern Calcareous Alps (Gosau Group, Austria) previously described as Neomeris circularis BADVE & NAYAK, is assigned to Neomeris mokragorensis sp. nov. Neomeris mokragorensis is characterized by a thin loosed skeleton formed only around ampullae, by which, besides the form of the ampullae, this species is clearly distinct from Neomeris cretacea (Steinmann).
