In the Bandar-e-Kangan region, Persian Gulf, Iran, fossilised bones of large vertebrates were found in the marine deposits of the Pabdeh Formation (Palaeogeneous rocks). A short expedition provided the certainty that there were probably archaeocete remains embedded in the Eocene beds of the Kangan anticline. However, the discovered surface finds were strongly weathered, so that a distinct determination was not possible. A targeted prospection and excavation is now planned in order to find and recover unweathered skeletal remains. The site is located in the corridor between the excellently documented basal archaeocetes from the shallow marine sediments of Indopakistan (Ypresian-Bartonian) and the western Tethys province of Wadi Al-Hitan in Egypt (Bartonian-Priabonian) with predominantly derived, fully marine representatives of the Basilosauridae.Findings from Iran could be of great importance for the interpretation of the phylogeny and development of the paraphyletic archaeocetes and could extend our knowledge regarding the evolution of cetaceans. Ultimately, further discussion depends on the success of our excavation activities, also on the nature and preservation of findings. Geodata from sites of discovery should help to reconstruct age and environment of discovered fossils.

在伊朗波斯湾的Bandar-e-Kangan地区，在Pabdeh组（古生岩）的海洋沉积物中发现了大型脊椎动物的化石。经过一次短暂的考察，确定康安背斜的始新世地层中可能埋藏着古鲸遗骸。然而，发现的地表发现物被强烈风化，因此不可能进行明确的测定。目前正在计划进行有针对性的勘探和挖掘，以寻找和恢复未风化的遗骸。该遗址位于印多巴基斯坦浅层海洋沉积物中记录良好的基底古细菌之间的走廊上（伊普雷西安-巴顿）和埃及西特提斯省的瓦迪希坦（Bartonian-Priabonian）主要是衍生的，来自伊朗的发现对于解释并系古生物的发生和发展可能非常重要，并且可以扩展我们对鲸类进化的了解。最终，进一步的讨论取决于我们的挖掘活动的成功，也取决于发现的性质和保存。来自发现地点的地理数据应该有助于重建发现化石的时代和环境。
