A freshwater ichthyofauna from the late Eocene Birket Qarun formation, Fayum, Egypt

摘要: ABSTRACT A collection of fossil fish teeth and other elements from Eocene deposits on the northshore Birket Qarun, Fayum Depression, Egypt, is reported. This adds significantly to our knowledge, as it consists material that was screened sediments, allowing small represent taxa not previously reported Fayum. Previous collections these sediments have concentrated larger remains generally elasmobranchs, which are marine species lower in section. Most this material, collected by screening at Qarun 2 (BQ-2) locality, represents fully freshwater fishes. It includes first record mormyrid Gymnarchus oldest for group, known only late Miocene or younger deposits. Similarly, Mochokidae (Siluriformes) Hydrocynus (Alestidae) site taxa. Other recovered os...
