Letná Formation
The Letná Formation is a Late Ordovician (Sandbian, or in the regional stratigraphy Berounian) geologic formation of the Prague Basin, Bohemian Massif in the Czech Republic. The formation crops out in the Czech capital, more specifically at Letná Hill, after which the formation is named. The type locality is located at Malá Strana, Holešovice district.Kříž & Steinová, 2009 The more than thick formation comprises a rhythmic alternation of sandstones (greywackes and subgreywackes), quartzites, intercalated with siltstones and shales deposited in marine flysch-like environments. Because of the excellent preservation, including gut remains, of a wide assemblage of early Paleozoic taxa in which trilobites dominate, the formation, which is lean in fossils in many areas but exceptionally rich in what has been interpreted as storm beds, has been designated a '' Konservat-Lagerstätte''. Description The Letná Formation was first formally defined in 1966 by Havlíček an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Marine Gastropod Genera In The Fossil Record
This list of marine gastropod genera in the fossil record is an attempt to list all the genera of sea snails or marine gastropod mollusks which have been found in the fossil record. Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell (sea slugs) to leave any recognizable traces. It is also worth pointing out that this list of genera represents only a very tiny fraction of the number of genera that must actually have existed over the evolutionary time span: the fossil record is an extremely patchy and exceedingly incomplete pteryrecord of life on earth in earlier geological eras. Many genera on this list are still extant, are still living now. On the current version of this list, some extant genera are mistakenly marked as extinct, with a "†" next to the name, but this should slowly become more accurate over time as corrections are made. The list consists of formal genera names in the class Gastropoda; it excludes purely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Hall (paleontologist)
James Hall Jr. (September 12, 1811 – August 7, 1898) was an American geologist and paleontologist. He was a noted authority on stratigraphy and had an influential role in the development of paleontology in the United States. Early life James Hall was born in Hingham, Massachusetts, the oldest of four children. His parents, James Hall Sr. and Sousanna Dourdain Hall, had emigrated from England two years earlier. Hall developed an early interest in science and enrolled in Rensselaer Polytechnic Institute, a recently established college that emphasized student participation and focused on science. He was a student of Amos Eaton and Ebenezer Emmons, both notable geologists. Hall graduated with honors in 1832, received his master's degree in 1833, and remained at Rensselaer to teach chemistry and later geology. In 1836 a multi-year survey was established to collect information on the geology and natural history of New York. For purposes of the survey, the state was divided into f ...

Carboniferous Gastropods
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' (" coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lin ...
