The Albian sediments of the Transdanubian Range in Hungary were deposited in non-marine to fully-marine environments. The studied sections revealed diverse benthic ostracod faunas with moderately-preserved specimens. Forty-six taxa are identified and Cypridea zalanyii n. sp. is newly described. The detailed palaeoecological study of these ostracod faunas provided an opportunity to distinguish eight assemblages. The assemblages include limnic, brackish lagoon, shallow marine, reef and low oxygenated semi-enclosed basin environments in the Northern Tethys region we investigated. This work contributes to the knowledge about Albian non-marine faunas from Europe and explores ecological requirements of brackish faunas.

匈牙利Transdanubian山脉的Albian沉积物沉积在从非海洋到完全海洋的环境中。所研究的部分揭示了具有适度保存的标本的各种底栖兽类动物群。鉴定出四十六个分类单元，而Cypridea  zalanyii n。sp。是新描述的。这些成龙类动物的详细古生态学研究提供了区分八种组合的机会。在我们调查的北部特提斯地区，这些组合包括边缘，咸淡水泻湖，浅海，礁石和低氧半封闭盆地环境。这项工作有助于了解欧洲的Albian非海洋动物区系，并探讨了咸淡动物区系的生态需求。
