Isolated pharyngeal teeth, pectoral, dorsal and suborbital fish spines were unearthed in a new outcrop located on the right bank of the Prut River, at Fălciu, Romania. They document Late Miocene aquatic ecosystems of the Dacian basin. Seven taxa were identified and described, six of them belonging to the order Cypriniformes and one to Siluriformes. The Cobitidae is here firstly reported in the fossil record of Romania. All the fish teeth and skeletal remains are from representatives marking shallow water. The fossils were probably buried into sediments accumulated near the mouth of a rather fast-flowing river that drained into a brackish body of water, part of the Dacian basin. The composition of the fauna is similar to the coeval ones from the North (Ukraine and Republic of Moldova) and from the South (Turkey) of the Black Sea basin.

来自罗马尼亚的 Maeotian(晚中新世)淡水鱼群

在罗马尼亚 Fălciu 的普鲁特河右岸的一个新露头中发现了孤立的咽齿、胸、背和眶下的鱼刺。他们记录了达契亚盆地的晚中新世水生生态系统。鉴定和描述了七个分类群,其中六个属于鲤形目,一个属于鲶形目。Cobitidae首先在罗马尼亚的化石记录中被报道。所有的鱼牙和骨骼残骸都来自标记浅水的代表。这些化石很可能被埋在一条流速相当快的河流口附近堆积的沉积物中,这条河流流入达契亚盆地的一部分咸水体。动物群的组成类似于来自黑海盆地北部(乌克兰和摩尔多瓦共和国)和南部(土耳其)的同时代动物群。
