Timothy Abbott Conrad [1] (June 21, 1803 in Trenton, New Jersey – August 9, 1877 in Trenton) [2] was an American geologist and malacologist.
He was from early life an investigator of American paleontology and natural history, devoting himself to the study of the shells of the Tertiary and Cretaceous formations, and to existing species of mollusks. In 1831 he began the issue of a work on “American Marine Conchology,” and the year following published the first number of his “Fossil Shells of the Tertiary Formation,” which was never completed. A “Monography of the Family Unionidae” was issued between 1835 and 1847. The lithographed plates in his publications were in part his own work. He contributed many articles to the American Journal of Science and the Journal of the Philadelphia Academy of Science. [3]
As one of the New York state geologists he prepared the geological report for 1837. He was paleontologist of the New York Geological Survey from 1838 until 1841, and wrote the annual reports in that department. He also made the reports of paleontological discoveries in the Pacific Railroad Survey and the Mexican Boundary Survey. [3]
He defended the theory of periodical refrigeration, and suggested that the Mississippi depression was the consequence of the upheaval of the Appalachians and the later elevation of the area of the Rocky Mountains. A list of his scientific papers is given in the catalogue of the Royal Society of England. [3] The American Philosophical Society elected Conrad to Membership in 1865 for his contributions to science. [4]
Josiah Dwight Whitney was an American geologist, professor of geology at Harvard University, and chief of the California Geological Survey (1860–1874). Through his travels and studies in the principal mining regions of the United States, Whitney became the foremost authority of his day on the economic geology of the U.S. Mount Whitney, the highest point in the contiguous 48 United States, and the Whitney Glacier, the first confirmed glacier in the United States, on Mount Shasta, were both named after him by members of the Survey.
John Strong Newberry was an American physician, geologist and paleontologist. He participated as a naturalist and surgeon on three expeditions to explore and survey the western United States. During the Civil War he served in the US Sanitary Commission and was appointed secretary of the western department of the commission. After the war he became professor of geology and paleontology at Columbia University School of Mines.
James Hall Jr. 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.
Samuel Stehman Haldeman was an American naturalist and philologist. During a long and varied career he studied, published, and lectured on geology, conchology, entomology and philology. He once confided, "I never pursue one branch of science more than ten years, but lay it aside and go into new fields."
William Henry Holmes, known as W. H. Holmes, was an American explorer, anthropologist, archaeologist, artist, scientific illustrator, cartographer, mountain climber, geologist and museum curator and director.
Henry Darwin RogersFRS FRSE LLD was an American geologist. His book, The Geology of Pennsylvania: A Government Survey (1858), was regarded as one of the most important publications on American geology issued up to that point.
Rollin Daniel Salisbury was an American geologist and educator.
Clarence Edward Dutton was an American geologist and US Army officer. Dutton was born in Wallingford, Connecticut on May 15, 1841. He graduated from Yale College in 1860 and took postgraduate courses there until 1862, when he enlisted in the 21st Connecticut Volunteer Infantry; he fought at Fredericksburg, Suffolk, Nashville and Petersburg. He was elected as a member to the American Philosophical Society in 1871.
William More Gabb was an American paleontologist.
The Paleontological Research Institution, or PRI, is a paleontological organization in Ithaca, New York, with a mission including both research and education. PRI is affiliated with Cornell University, houses one of the largest fossil collections in North America, and publishes, among other things, the oldest journal of paleontology in the western hemisphere, Bulletins of American Paleontology.
Charles Conrad Abbott was an American archaeologist and naturalist.
The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, it extends throughout much of the Appalachian Basin.
Robert Thomas Hill was a significant figure in the development of American geology during the late 19th and early 20th centuries. As a pioneer Texas geologist, Hill discovered and named the Comanche series of the Lower Cretaceous, and was a lifelong student of the structure and stratigraphy of the Cretaceous deposits of Central Texas and neighboring regions.
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists.
James Culbertson McConnell, usually abbreviated as J. C. McConnell was one of the world's most acclaimed scientific illustrators.
William Williams Mather was an American geologist.
Julia Anna Gardner, was an American geologist who worked for the United States Geological Survey for 32 years, was known worldwide for her work in stratigraphy and mollusc paleontology.
Alexander Winchell was a United States geologist who contributed to this field mainly as an educator and a popular lecturer and author. His views on evolution aroused controversy among his contemporaries; today the racism of these views is more cause for comment.
The Bridger Formation is a geologic formation in southwestern Wyoming. It preserves fossils dating back to the Ypresian Epoch of the Paleogene Period. The formation was named by American geologist Ferdinand Vandeveer Hayden for Fort Bridger, which had itself been named for mountain man Jim Bridger. The Bridger Wilderness covers much of the Bridger Formation's area.
Eoconus sauridens is an extinct species of sea snail, a marine gastropod mollusk, in the family Conidae.
