The first results of the investigation of the Late Jurassic (Kimmeridgian–early Tithonian) fish fauna from the fossil-rich Pálihálás Limestone Formation (“Long trench”, Eperkés-hegy, Olaszfalu, Hungary) are detailed here. The present study provides the first systematic faunal data of a Jurassic marine fish community from the Transdanubian Mountains. The low-diversity neoselachian fauna includes Notidanodon sp., Sphenodus sp., and indeterminate synechodontiform, possible indeterminate scyliorhinids, and further, yet indeterminate forms. Actinopterygians are represented by Caturus sp. and indeterminate actinopterygian teeth and scales. The Olaszfalu hexanchid is the most similar to Notidanodon lanceolatus; however, specific determination is not possible. The Olaszfalu record is the second Jurassic (and also the earliest) report of the genus Notidanodon, which re-dates the earliest occurrence of Hexanchidae back into the boundary of the Kimmeridgian–early Tithonian.

Eperkés-hegy（Olaszfalu，Bakony山，匈牙利）的晚侏罗世（基米第纪-蒂通尼早期）鱼类区系：Notidanodon Cappetta的最古老记录，1975年，中生六足类的短记录

这里详细介绍了对化石含量丰富的帕利哈拉斯石灰岩组（“长沟”，匈牙利奥拉兹法鲁的埃佩尔凯什-赫吉）“侏罗纪晚期（基默尼迪安-蒂通尼早期）”鱼类区系进行调查的初步结果。本研究提供了来自跨丹努比山脉的侏罗纪海鱼群落的第一个系统动物区系数据。低多样性新狼蛛动物群包括Notidanodon sp。，Sphenodus sp。和不确定的滑突齿形，可能不确定的鞘龙，以及进一步但不确定的形式。放线翅目由卡特鲁斯（Caturus sp。）代表。和不确定的放线翅目牙齿和鳞片。Olaszfalu hexanchid与Notidanodon lanceolatus最相似; 但是，具体的确定是不可能的。Olaszfalu记录是Notidanodon属的第二个侏罗纪（也是最早的）报告，该记录将Hexanchidae的最早发生重新追溯到Kimmeridgian-Tithonian的边界。
