Glyphis (shark)
''Glyphis'' is a genus in the family (biology), family Carcharhinidae, commonly known as the river sharks. They live in rivers or coastal regions in and around south-east Asia, Africa and parts of Australia. Taxonomy This genus contains only three extant species. Further species could easily remain undiscovered due to their secretive habits. This genus was thought to contain five different species, but recent studies on molecular data revealed that the species ''Ganges shark, Glyphis gangeticus'' has an irregular distribution in the Indo-West Pacific region. The genus Glyphis is closest to the genus Lamiopsis. Species The recognized species in this genus are: * ''Glyphis fowlerae'' Compagno, White & Cavanagh, 2010 (Borneo river shark) synonym of ''G. gangeticus'' * ''Glyphis gangeticus'' (Johannes Peter Müller, J. P. Müller & Friedrich Gustav Jakob Henle, Henle, 1839) (Ganges shark) * ''Glyphis garricki'' Leonard Joseph Victor Compagno, L. J. V. Compagno, William Toby White, W ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
