Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotaliida Genera
The Rotaliida are an order of Foraminifera, characterized by multilocular tests (shells) composed of bilamellar perforate hyaline lamellar calcite that may be optically radial or granular. In form, rotaliid tests are typically enrolled, but may be reduced to biserial or uniserial, or may be encrusting with proliferated chambers. Chambers may be simple or subdivided by secondary partitions; the surface is smooth, papillate, costate, striate, or cancellate; the aperture is simple or with an internal toothplate, entosolenian tube, or hemicylindrical structure; it may have an internal canal or stolen systems. Rotaliids are primarily oceanic benthos, although some are common in shallower estuarine waters. They also include many important fossils, such as the nummulitids. Taxonomy The Rotaliida are now divided into the following superfamilies: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helen Niña Tappan Loeblich
Helen Niña Tappan Loeblich (October 12, 1917 – August 18, 2004) was an American micropaleontologist who was a professor of geology at the University of California, Los Angeles, a United States Geological Survey (USGS) biostratigrapher, and a scientific illustrator whose micropaleontology specialty was research on Cretaceous foraminifera. Early life Dr Helen Nina Tappan Leoblich was born on October 12, 1917, in Norman, Oklahoma. She came from a well-educated background. Her mother Mary Pearl Jenks Tappan was a math teacher at Cornell, and her father, Frank Girard Tappan, was a Dean of Electrical Engineering at the University of Oklahoma. Education Tappan Loeblich earned her BS in 1937 and her Master's in 1939, both in geology from the University of Oklahoma. Her master's thesis was on mid-Cretaceous foraminifera of Oklahoma and Texas. At the University of Oklahoma, she met her future husband and long time scientific collaborator, Alfred R. Loeblich Jr, in chemistr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
