Podiceps Csarnotanus
''Podiceps csarnotanus'' is an extinct species of Upper Pliocene grebe from Hungary. History The species was described by Eugene Kessler in 2009 as part of a series of papers that described fossil material that have been retrieved form the Carpathian Basin. The species name "csarnotanus" is named after the site it was discovered Csarnóta. Description The holotype (MÁFI V. 09. 61. 1) is the distal fragment of the right ulna, which the size of it falls in between the horned grebe (''P. auritus'') and the red-necked grebe (''P. grisegena''). In comparison to the recent species of ''Podiceps'' and the ''Aechmophorus'', the condylus ventralis is elongated and prominent. The condylus dorsalis is rounded, while in modern ''Podiceps'' and ''Aechmophorus'' it just emerges. The cranial surface of the diaphysis is slightly convex, not flat unlike in modern ''Podiceps''. Paleobiology ''P. csarnotanus'' comes from the Carpathian Basin which is located in South Hungary. The locality of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
