Abstract
In the median part of the Velebit Mt. (SW Croatia, Yugoslavia) black limestones of the Zone Neoschivagerina craticulifera have been investigated. Numerous fossils (175 taxa) have been determined and arranged into the fossil communities. The relationship between the type of sediment and the composition of fossil community has been studied. It was concluded that, during the Murghabian, the investigated region represented a shallow marine carbonate platform, settled in subtropic climatic belt. Sea floor was overgrown with algal plains. At several places mud-mounds and patchreefs were created by fixosessile organisms. Sediments at the eastern edge of the zone were deposited in an intraplatform depression.

Summary
Geološko-paleontološki zavod Prirodoslovno-matematičkog fakulteta, Ulica Kralja Zvonimira 8, 41000 Zagreb. Određenojeukupnostosedamdesetpettaksonamikro fosila i makrofosila, utvrđena je njihova pripadnost određenim fosilnim zajedni cama, kao i odnos prema tipu sedimenta. Zaključeno je da je istraženo područje u vrijeme murgaba predstavljalo plitkomorsku karbonatnu platformu smještenu u suptropskom klimatskom po jasu. Morsko dno bilo je obraslo algalnim livadama, unutar kojih su se na nekoliko mjesta formirali muljni humci i krpasti grebeni. Sedimenti na krajnjem istoku zone taložili su se u intraplatformskoj depresiji
