对虾类鱼的分类仍在讨论中。一些谱系，包括Eleotridae和Butidae，仍然很难描述，因为突触形态很罕见(Eleotridae)或尚未确定(Butidae)。此外，这些物种的化石记录也很稀少。来自渐新世最上层沉积物的保存异常完好的鱼化石，其中有耳石(≈23-24Mio.Y.ago)提供了迄今为止对金鱼化石最深入的描述。该种最初被描述为Cottus Aries Agassiz，然后转移到†LEpocottus Sauvage，并随后被分配给戈比乌斯。根据对分生组织、骨学和耳石数据的比较分析，该物种很可能是Butidae科的成员。这一发现很重要，因为它代表了基于欧洲关节骨骼的第一个记录的Butid鱼化石。Butidae和Eleotridae目前分布在非洲西部、马达加斯加、亚洲和澳大利亚，但它们没有出现在欧洲，也没有出现在地中海。新的结果表明，在渐新世和中新世早期，几种Butidae在欧洲繁衍生息。与最近的Butidae和Eleotridae类似，这些鱼适应广泛的盐度，在淡水、微咸水和边缘海洋生境中繁衍生息。Butidae化石在中新世早期从欧洲、地中海和帕拉提斯地区消失，可能是因为与在这段时间辐射的其他戈壁滩相比，它们缺乏竞争力。此外，这项研究还证明了耳石对于鹦鹉类系统学的重要价值。
The classification of gobioid fishes is still under discussion. Several lineages, including the Eleotridae and Butidae, remain difficult to characterize because synapomorphies are rare (Eleotridae) or have not yet been determined (Butidae). Moreover, the fossil record of these groups is scarce. Exceptionally well-preserved fish fossils with otoliths in situ from uppermost Oligocene sediments (≈23–24 Mio. y. ago) in Southern France provide the most in-depth description of a fossil gobioid to date. The species was initially described as Cottus aries Agassiz, then transferred to †Lepidocottus Sauvage, and subsequently assigned to Gobius. Based on a comparative analysis of meristic, osteological and otolith data, this species most likely is a member of the family Butidae. This discovery is important because it represents the first record of a fossil butid fish based on articulated skeletons from Europe. The Butidae and Eleotridae are currently distributed in W-Africa, Madagascar, Asia and Australia, but they do not appear in Europe and also not in the Mediterranean Sea. The new results indicate that several species of the Butidae thrived in Europe during the Oligocene and Early Miocene. Similar to the recent Butidae and Eleotridae, these fishes were adapted to a wide range of salinities and thrived in freshwater, brackish and marginal marine habitats. The fossil Butidae disappeared from Europe and the Mediterranean and Paratethys areas during the Early Miocene, due probably to their lack of competitiveness compared to other Gobioidei that radiated during this period of time. In addition, this study documents the great value of otoliths for gobioid systematics.
