Around the Paleogene-Neogene boundary (some 25 Mya), barn owls were the dominant group of owls in southern Europe and adjacent Asia at least; the distribution of fossil and present-day owl lineages indicates that their decline is contemporary with the evolution of the different major lineages of true owls, which for the most part seems to have ...
The Neogene (/ ˈ n iː. ə dʒ iː n / NEE-ə-jeen, [6] [7]) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.04 million years ago to the beginning of the present Quaternary Period 2.58 million years ago.
The Paleogene Period (IPA: / ˈ p eɪ l i. ə dʒ iː n,-l i. oʊ-, ˈ p æ l i-/ PAY-lee-ə-jeen, -lee-oh-, PAL-ee-; also spelled Palaeogene or Palæogene) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period 66 Ma (million years ago) to the beginning of the Neogene Period 23.04 Ma.
Tyto robusta was a prehistoric barn-owl.It lived at what is now Monte Gargano in Italy, and was an island throughout much of the Neogene when sea levels were higher. The owl's remains date back to the Miocene-Pliocene boundary 5.5 to 5 million years ago.
Ogygoptynx is an extinct genus of owl from the Paleocene. [1] Dated to the Late Paleocene, this is the earliest known owl fossil, with a single species assigned to the taxon: Ogygoptynx wetmorei . [ 2 ]
A finer subdivision was established by Pierre Mein in 1975, who divided the Neogene in 17 zones, known as the MN zonation, indicated by the letters MN (Mammal Neogene) and a number. Similarly, a more detailed subdivision for the Paleogene period was established. There are 30 such Mammal Paleogene zones (MP1 to MP30, numbered from old to young). [2]
The supposed "giant barn owl" Basityto from the Early Eocene of Grafenmühle (Germany) was actually a crowned crane (Balearica); [16] the presumed "Easter Island barn owl", based on subfossil bones found on Rapa Nui, has turned out to be a procellarid; [17] and the specimen originally described as the fossilized Pliocene Lechusa stirtoni was ...
The Mammal Neogene zones or MN zones are system of biostratigraphic zones in the stratigraphic record used to correlate mammal-bearing fossil localities of the Neogene period of Europe. It consists of seventeen consecutive zones (numbered MN 1 through MN 18; MN 7 and 8 have been joined into MN 7/8 zone) defined through reference faunas, well ...
