Somosaguas Paleontological Site
The Somosaguas fossil site is located in the Community of Madrid, in the Somosaguas campus, within the municipality of Pozuelo de Alarcón (Spain). The fossils found belong to the fauna of the Aragonian Stage (stratigraphy), continental stage (middle Miocene), about 14 million years ago. The sediments where the remains are found were deposited in an alluvial fan Depositional environment, sedimentary environment. The Paleontological site, site itself is formed by two zones with fossil presence, separated by : Somosaguas Norte, which occupies an upper Stratigraphy, stratigraphic position, and Somosaguas Sur. The site was discovered in 1989 by a geology student near the Faculty of Political Sciences of the Complutense University, when he observed bone fragments in the ground. The student reported the discovery to Professor Nieves López Martínez, who verified that the remains were fossils, and in turn reported it to the Department of Paleobiology of the Museo Nacional de Ciencias Na ...

Langhian
The Langhian is, in the ICS geologic timescale, an age or stage in the middle Miocene Epoch/Series. It spans the time between 15.97 ± 0.05 Ma and 13.65 ± 0.05 Ma (million years ago) during the Middle Miocene.GeoWhen (2007) The Langhian was a continuing warming period defined by Lorenzo Pareto in 1865, it was originally established in the Langhe area north of Ceva in northern Italy, hence the name. The Langhian is preceded by the Burdigalian and followed by the Serravallian Stage. Stratigraphic definition The base of the Langhian is defined by the first appearance of foraminifer species ''Praeorbulina glomerosa'' and is also coeval with the top of magnetic chronozone C5Cn.1n. A GSSP for the Langhian Stage was not yet established in 2009. The top of the Langhian Stage (the base of the Serravallian Stage) is at the first occurrence of fossils of the nanoplankton species ''Sphenolithus heteromorphus'' and is located in magnetic chronozone C5ABr. The Langhian is coeval with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
