Maurice Mehl
Maurice Goldsmith Mehl (1887 - 1966) was an American paleontologist and professor in the Department of Geology at the University of Missouri. Life and career Mehl was born on December 25, 1887, to Frank and Rebecca Goldsmith Mehl. After graduation from Burlingame High School, he attended the University of Chicago, where he completed a B.S. in 1911 and a Ph.D. in 1914. While at Chicago, he met Lucy Jane Hull and they were married in 1912. At Chicago, Mehl studied vertebrate paleontology under the instruction of prominent paleontologist Samuel Wendell Williston. He taught at Chicago for awhile as well as at University of Wisconsin, University of Oklahoma, and Denison University before joining the University of Missouri in 1919. In addition to teaching and researching at Missouri until his retirement in 1958, where he became known simply as "Doc" Mehl, he also worked as a consultant to the Missouri Geological Survey and Water Resources. While at Missouri, he had a long and produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Branson
Edward B. Branson was an American geologist and paleontologist. He was a professor of geology at the University of Missouri. Overview of career Branson earned his doctorate at the University of Chicago and joined the Geology department at the University of Missouri in 1911. During his doctoral studies, he had spent time searching for fossils near Lander, Wyoming and so he determined to set up a camp for the hands-on study of geology and paleontology nearby. Also in 1911, he came to Lander with a group of students and established the Missouri Field Geology Camp, which is now known as the Branson Field Laboratory, near Sinks Canyon State Park. The Branson Field Laboratory appears to be the oldest continually operated field geology camp in the United States. Eventually Branson formed a scientific partnership with Maurice "Doc" Mehl, another Chicago graduate who joined the Missouri faculty in 1919. Branson retired in 1948, which is when the camp was renamed in his honor. Contribu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Chordata
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also Bilateral symmetry, bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit Metameric, metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cep ...

Conodont
Conodonts (Greek ''kōnos'', "cone", + ''odont'', "tooth") are an extinct group of agnathan (jawless) vertebrates resembling eels, classified in the class Conodonta. For many years, they were known only from their tooth-like oral elements, which are usually found in isolation and are now called conodont elements. Knowledge about soft tissues remains limited. They existed in the world's oceans for over 300 million years, from the Cambrian to the beginning of the Jurassic. Conodont elements are widely used as index fossils, fossils used to define and identify geological periods. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity. Discovery and understanding of conodonts The teeth-like fossils of the conodont were first discovered by Heinz Christian Pander and the results published in Saint Petersburg, Russia, in 1856. The name ''pander'' is commonly used in scientific names of conodonts. It was only in the early 1980s that the first fossil evidence of ...

Dinantian
Dinantian is the name of a series (stratigraphy), series or Epoch (reference date), epoch from the Lower Carboniferous system (stratigraphy), system in Europe. It can stand for a series of rocks in Europe or the time span in which they were deposited. The Dinantian is equal to the lower part of the Mississippian age, Mississippian series in the international geologic timescale of the International Commission on Stratigraphy, ICS. The Dinantian is named for the Belgian city of Dinant where strata of this age occur. The name is still used among European geologists. Earlier terms for the Dinantian were Bernician Series, Bernician from the Anglo-Scottish borderland, and Avonian (divided into upper (Kidwellian) and lower (Clevedonian) substages) from Kidwelly on the Welsh and Clevedon on the English sides of the Bristol Channel.

Taxa Named By Maurice Mehl
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
