The Carnivora (Mammalia) yielded in the coal mine Gračanica in Bosnia and Herzegovina are composed of the caniform families Amphicyonidae (Amphicyon giganteus), Ursidae (Hemicyon goeriachensis, Ursavus brevirhinus) and Mustelidae (indet.) and the feliform family Percrocutidae (Percrocuta miocenica). The site is of middle Miocene age and the biostratigraphical interpretation based on molluscs indicates Langhium, correlating Mammal Zone MN 5. The carnivore faunal assemblage suggests a possible assignement to MN 6 defined by the late occurrence of A. giganteus and the early occurrence of H. goeriachensis and P. miocenica. Despite the scarcity of remains belonging to the order Carnivora, the fossils suggest a diverse fauna including omnivores, mesocarnivores and hypercarnivores of a meat/bone diet as well as Carnivora of small (Mustelidae indet.) to large size (A. giganteus). Faunal similarities can be found with Prebreza (Serbia), Mordoğan, Çandır, Paşalar and Inönü (all Turkey), which are of comparable age. The absence of Felidae is worthy of remark, but could be explained by the general scarcity of carnivoran fossils. Gračanica records the most eastern European occurrence of H. goeriachensis and the first occurrence of A. giganteus outside central Europe except for Namibia (Africa). The Gračanica Carnivora fauna is mostly composed of European elements.

食肉动物(哺乳动物),来自格拉恰尼察(Bogojno Basin,Gornji Vakuf,波斯尼亚和黑塞哥维那)中新世中期

波斯尼亚和黑塞哥维那的Gračanica煤矿中产的食肉动物(哺乳动物)由犬的两栖动物科:两栖类(Amphicyon gigaeus),Ursidae(Hemicyon goeriachensisUrsavus brevirhinus)和Mustelidaeecute(microcrocuta)(fe形纲) 。该地点处于中新世中期,基于软体动物的生物地层学解释表明Lang与哺乳动物5区MN 5有关。食肉动物的动物群暗示可能是由A. giganteus的晚期发生和H的早期发生所定义的MN 6 。 goeriachensisP. miocenica。尽管属于食肉目遗体的稀缺性,该化石表明一个多样化的动物,包括杂食动物,mesocarnivores和肉/骨饮食hypercarnivores以及小的食肉目(鼬indet)到大尺寸(A.巨)。在普雷布雷扎(塞尔维亚),莫尔多安(Mordogan),桑德尔(Candır),帕萨拉(Paşalar)和伊努(Inönü)(全土耳其)年龄相似,可以发现动物的相似之处。缺乏猫科动物值得一提,但可以用食肉动物化石普遍缺乏来解释。Gračanica记录了欧洲东部最常见的H. goeriachensis发生和除中纳米比亚(非洲)以外在中欧以外首次出现的巨型A. giganteus。GračanicaCarnivora动物区系主要由欧洲元素组成。
