Ferganoceratodus
''Ferganoceratodus'' is a genus of prehistoric lungfish known from the Jurassic and possibly Early Cretaceous of Asia. It is a basal member of the suborder Ceratodontoidei. Despite only being known from Mesozoic-aged rocks, phylogenetic analyses indicate that it diverged from the rest of the suborder around 300 million years ago, during the late Carboniferous. Species The following species are currently classified in the genus: * †''Ferganoceratodus annekempae'' Cavin, Deesri & Chanthasit, 2020 (named after Anne Kemp) Phu Kradung Formation, Thailand, Late Jurassic-?earliest Cretaceous * †''Ferganoceratodus jurassicus'' Nessov and Kaznyshkin, 1985 Balabansai Formation The Balabansai Formation (sometimes transcribed Balabansay, also known as Balabansai Svita) is a geological formation in Kazakhstan, Kyrgyzstan and Uzbekistan whose strata date back to the Bathonian and Callovian stages of the Middle Jurassic.

Anne Kemp
Anne Kemp is an Australian ichthyologist and paleoichthyologist who specializes in lungfishes (order Dipnoi). Her primary area of study is the Australian lungfish (''Neoceratodus forsteri''). She has served as a research fellow at Griffith University since 2010. Prior to this, she had also served as a research fellow at Queensland Museum between 1980 and 1991, and at the Centre of Microscopy at the University of Queensland between 1999 and 2008. Kemp's pioneering work was with Australian lungfish in the Brisbane River and at Enoggera Reservoir beginning in 1969; they are no longer thought to exist at the latter location. She has documented the decline of the species at many locations in Queensland at due to environmental degradation, finding significant lack of recruitment in the populations due to the construction of dams, and supports conservation efforts for the endangered species. Aside from her work with the Australian lungfish, Kemp also studies the evolutionary history of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
