土耳其中北部奥尔哈尼耶盆地始新世中期 Uzunçarşıdere 地层中描述了两个新的安那托利亚德尔菲亚兽 Orhaniyeia nauta 标本。这些标本增强了我们对该分类群齿列的了解，揭示了 Orhaniyeia 的 P3 和 p3 与其姊妹分类群 Anatoliadelphyn 的齿列相似，被增大且高度膨胀，表明这两个分类群都以硬食性食物为食。 Anatoliadelphyids 的祖先牙齿形态可能与 Orhaniyeia nauta 相似，而 Anatoliadelphys 的牙列是自体的。结合 Orhaniyeia 的新数据进行的系统发育分析将 anatoliadelphyids 构建为嵌套在多种但通常记录很少的早期古近纪布诺多冈瓦纳有袋动物组合中，这些有袋动物通常与多多洛皮类动物有亲缘关系。基于Anatoliadelphysalone的替代系统发育重建表明，peradectid或protodidelphid与anatoliadelphyids有亲缘关系，但这些假设并未得到Orhaniyeia的新数据的支持。 Anatoliadelphyids 很可能从南部（非洲/阿拉伯）殖民巴尔干纳托利亚，尽管目前没有化石记录表明这种冈瓦纳布诺多类有袋动物分支曾经居住在非洲/阿拉伯。奥哈尼耶的硬食性饮食可能是不拘一格的，但重点是腹足类动物。澳大利亚中新世有袋动物 Malleodectes 也提出了类似的饮食重建，其牙列与 Orhaniyeia 的牙列显着趋同。Orhaniyeia 和 Anatoliadelphys 似乎利用了不同的生态位，因为 Anatoliadelphys 的自体牙列包括增强肉食性的多种特化。马纳托利亚在巴尔干纳托利亚的殖民引发了一种小型的地方性辐射，这种模式被巴尔干纳托利亚的多个其他哺乳动物分支所复制。
Two new specimens of the anatoliadelphyid metatherianOrhaniyeia nautaare described from the middle Eocene Uzunçarşıdere Formation in the Orhaniye Basin, north-central Turkey. These specimens augment our knowledge of the dentition of this taxon, revealing that P3 and p3 ofOrhaniyeiaresemble those of its sister taxonAnatoliadelphysin being enlarged and highly inflated, suggesting that both taxa consumed a durophagous diet. The ancestral dental morphology of anatoliadelphyids likely approximated that ofOrhaniyeia nauta, whereas the dentition ofAnatoliadelphysis autapomorphous. A phylogenetic analysis incorporating the new data forOrhaniyeiareconstructs anatoliadelphyids as nested among a diverse, but generally poorly documented, assemblage of early Paleogene bunodont Gondwanan marsupials that are typically allied with polydolopimorphians. Alternative phylogenetic reconstructions based onAnatoliadelphysalone have suggested either peradectid or protodidelphid affinities for anatoliadelphyids, but these hypotheses are not supported by the new data fromOrhaniyeia. Anatoliadelphyids likely colonized Balkanatolia from the south (Africa/Arabia), even though there is no current fossil record indicating that this Gondwanan bunodont marsupial clade ever inhabited Africa/Arabia. The durophagous diet ofOrhaniyeiawas probably eclectic, but with an emphasis on gastropods. A similar dietary reconstruction has been proposed for the Australian Miocene marsupialMalleodectes, the dentition of which is remarkably convergent with that ofOrhaniyeia.OrhaniyeiaandAnatoliadelphysappear to have exploited distinct ecological niches, because the autapomorphous dentition ofAnatoliadelphysincludes multiple specializations for enhanced carnivory. The colonization of Balkanatolia by anatoliadelphyids instigated a small endemic radiation, a pattern that was replicated by multiple other Balkanatolian mammal clades.
