Eocene actinopterygian fishes from Pakistan, with the description of a new genus and species of channid (Channiformes)

A collection of fossil material from Eocene deposits of Pakistan includes remains belonging to various taxa of actinopterygian fishes. The material comes from predominantly freshwater deposits, as well as a few marine deposits, in the Kuldana Formation in the Kala Chitta Hills, and from the Chorgali Formation near Gali Jaghir, in Attock District of Punjab Province. The Kuldana and Chorgali formations are early to middle Eocene in age. Isolated bones and teeth are identified as belonging to Eotrigonodontidae, Pycnodontiformes, Amiidae, Osteoglossidae, Siluriformes (cf. Bagridae), and Perciformes, as well as unidentified Teleostei. Some of the fossils are skulls of a channiform fish, which is here described as a new genus and species, Anchichanna kuldanensis. The faunal affinities of the Indo-Pakistan area during the Eocene are not clear, with previous studies suggesting it is faunally more similar to other parts of modern Asia, others as it representing a region of endemism, or even as being similar to northern Africa. The fish material reported here indicates a relationship between the Pakistan fauna in the Eocene with that of northern Africa.

Eocene mammal faunas from northern Indo-Pakistan

We present a summary of the Eocene mammal faunas of Indo-Pakistan based on study of the known faunas and new collections. New taxa described here are the carpolestid Parvocristes oligocollis, the plesiadapid Jattadectes mamikheli (both new families for the subcontinent), the hyaenodontid Paratritemnodon jandewalensis, the arctocyonid Karakia longidens, the raoellid Khirtharia aurea, and the helaletid Jhagirilophus chorgalensis. Based on the faunal evidence and considering the geological setting, we also evaluate the uniformity of the Eocene faunas from northern Indo-Pakistan. Tentatively, we propose that three chronologically distinct faunas occur in Northern Indo-Pakistan. These are, from oldest to youngest, (1) the Banda Daud Shah Fauna, (2) the Ganda Kas Fauna, and (3) the Kalakot Fauna. Although there are broad similarities between these faunas and Eocene faunas of the Northern Hemisphere, the Indian subcontinent retained a highly distinctive fauna in that period.
