Acer Chaneyi
''Acer chaneyi'' is an extinct maple species in the family Sapindaceae described from a number of fossil leaves and samaras. The species is known from Oligocene to Miocene sediments exposed in Alaska, Idaho, Nevada, Oregon and Washington in the U.S. It is one of several extinct species belonging to the living section '' Rubra''. Taxonomy ''Acer chaneyi'' is known from leaf and samara specimens which were recovered from a number of different formations in Western North America. The oldest occurrence is from the possibly Early Oligocene Gumboot Mountain flora of Southern Washington state followed by the Late Oligocene Kukak Bay flora in Alaska. In the early Miocene ''A. chaneyi'' is known from the Alaskan Kanalku Bay flora, Oregon Collawash and Little Butte flora. The Middle Miocene locations include the Skolai Creek flora of Alaska, Grand Coulee and Latah floras of Washington, Mascall flora and Succor Creek floras in Oregon and the Latah and Clarkia flora in Idaho.

Moraceae
The Moraceae — often called the mulberry family or fig family — are a family of flowering plants comprising about 38 genera and over 1100 species. Most are widespread in tropical and subtropical regions, less so in temperate climates; however, their distribution is cosmopolitan overall. The only synapomorphy within the Moraceae is presence of laticifers and milky sap in all parenchymatous tissues, but generally useful field characters include two carpels sometimes with one reduced, compound inconspicuous flowers, and compound fruits. The family includes well-known plants such as the fig, banyan, breadfruit, jackfruit, mulberry, and Osage orange. The 'flowers' of Moraceae are often pseudanthia (reduced inflorescences). Historical taxonomy Formerly included within the now defunct order Urticales, recent molecular studies have resulted in the family's placement within the Rosales in a clade called the urticalean rosids that also includes Ulmaceae, Celtidaceae, Cannabaceae, ...

Diospyros
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". Muddled translations sometimes give rise to curious and inappropriate interpretations such as " God's pear" and " Jove's fire". The genus is a large one a ...

Myricaceae
The Myricaceae are a small family of dicotyledonous shrubs and small trees in the order Fagales. There are three genera in the family, although some botanists separate many species from ''Myrica'' into a fourth genus ''Morella''. About 55 species are usually accepted in ''Myrica'' (with ''Morella'' included), one in ''Canacomyrica'', and one in '' Comptonia''. Well-known members of this family include bayberry and sweetfern. * ''Canacomyrica'' Guillaumin 1940 * '' Comptonia'' L'Hér. ex Aiton 1789 * ''Myrica ''Myrica'' is a genus of about 35–50 species of small trees and shrubs in the family Myricaceae, order Fagales.

Celastraceae
The Celastraceae (staff-vine or bittersweet) are a family of 97 genera and 1,350 species of herbs, vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only ''Celastrus'' (the staff vines), ''Euonymus'' (the spindles) and ''Maytenus'' widespread in temperate climates, and ''Parnassia'' (bog-stars) found in alpine and arctic climates. Of the 97 currently recognized genera of the family Celastraceae, 19 are native to Madagascar and these include at least 57 currently recognized species. Six of these 19 genera ('' Brexiella'', '' Evonymopsis'', '' Hartogiopsis'', ''Polycardia'', ''Ptelidium'', and ''Salvadoropsis'') are endemic to Madagascar.

Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Earth, an ...
