美国联邦地质调查局(The United States Geological Survey --USGS) 成立于1879年3月3日，它是隶属于美国政府的科学研究机构。130多年以来，USGS雇佣了多名研究植物化石的专家，如：Lester Frank Ward (1841--1913) [Assistant: David White]

William M, Fontaine（1835--1913），John S. Newberry（1822--1892），David White（1862--1935），Frank Hall Knowlton（1860--1926），Roland W. Brown(1893--1961)，Charles B. Read （1907--1979） (Assistant: Jack Murata)，James  M. Schopf(1911--1978)，Sergius H. Mamay(1920--2008) (Assistant: Arthur Dwight Watt,1921--??)，JackA. Wolfe(1936--2005)等[注：有些工作时间很短]。根据有关法律和规定，这些雇员也在美国国家博物馆(USNM)或后来的美国国家自然历史博物馆(NMNH)开展植物化石的采集、馆藏和研究工作。

     通过“Umbrella of American palaeobotany（美国古植物学之伞）”的系统性研究，我们期望为中国和其他地区的古植物学发展提供借鉴。

    1951年，美国古植物学家Sergius H. Mamay (1920--2008)开始供职于美国联邦地质调查局。与此同时，他也在美国国家博物馆(USNM)或后来的美国国家自然历史博物馆(NMNH)工作，直到1982年退休。

（1）Sergius H. Mamay的教育背景

   1947—1950年，Sergius H. Mamay在华盛顿大学植物系（Washington University，St. Louis）跟随著名古植物学Henry N Andrews （1910--2002）攻读硕士和博士学位，主要从事煤核植物(coal balls)的研究。

（2）Sergius H. Mamay的科学成就

   关于Sergius H. Mamay的学术成就，他的同事们如此评价：

“Serge Mamay was also one of the world’s foremost experts on late Paleozoic plant fossils,particularly those of Permian age. He brought together and identified a large collection of plant fossils now deposited in the Smithsonian Institution which specialists from around the world visit to compare and investigate. Among his numerous publications, the well-known 1964 monograph with Charles B. Read—“Upper Paleozoic Floral Zones and Floral Provinces of the United States” — is among the most of the cited papers published on American Paleozoic plants. Similarly,Serge’s “Paleozoic Origin of the Cycads,” published in 1976, is a landmark paper with broad, lasting significance. Serge also published a large body of work describing new taxa and floras of the late Paleozoic age from the western United States, erecting no less than 19 new genera of fossil plants, most for unusual plant remains from the Permian of north central Texas. The latest of his works, scheduled for publication later this year, includes the first descriptions of the genus Comia in North America and a new genus, Auritifolia. Serge was a quiet but intense man who was devoted to his research and blessed with aphotographic memory of the scientific literature.”
