Asterocalculus heraki n. gen., n. sp., a new calcareous alga (Gymnocodiaceae) from the Upper Triassic Hauptdolomite of Žumberak, North Croatia
A sample of Upper Triassic, early diagenetic, peritidal dolomite (Hauptdolomite) from western Žumberak (north Croatia) contains a new species of calcareous algae (family Gymnocodiaceae). The new algal species is accompanied by rich foraminiferal assemblage consisting of numerous Triasina hantkeni, Auloconus permodiscoides and Aulotortus sinuousus, and less numerous Aulotortus friedli and A. tenuis. The new algal species is represented by numerous variously oriented sections which enable the accurate description and interpretation of its morphologic features of both outer shape and inner structure. In the present paper the new algal species is described as Asterocalculus heraki n. gen., n. sp., characterized by a cylindrical thallus with loosely spaced levels of tubular protrusions, supposedly functioning as another type of reproductive structures, in addition to 'conceptacles', or having some unknown physiological function.
