Scope
This is an evolving collection of significant people in dinosaur science, past and present. Amateurs have made some major contributions to our understanding of dinosaurs but we owe most to the highly qualified paleontologists who conduct field work, teach in universities, supervise and curate museum collections or work in private enterprise.

It is our goal that this directory include a short biography (particularly any dinosaurs named) and useful Internet links related to the person and their work.

A work-in-progress
As you can see we are currently expanding the people profiles. We shall also be progressively adding the dinosaurs each person has been involved in naming.

Professor in the Department of Geosciences at Indiana University-Purdue University, Fort Wayne, Texas.

David E. Fastovsky
Dr Fastovsky research foci include The evolution of Mesozoic terrestrial paleoenvironments, particularly those that contain dinosaurs and other terrestrial vertebrates. Many paleobiological questions are uniquely addressed through geological means, and so for than 20 years he have been studying the sedimentary geology of a variety of terrestrial settings – from the Triassic of Arizona, to the Cetaceous of Mongolia and Mexico, to the Cretaceous/Tertiary boundary in the upper Great Plains of the United States. Because dinosaurs are preserved in sedimentary rocks, he has also investigated the dinosaur extinction as well as the environments of their origin. Dr Fastovsky is Professor of Geosciences at the University of Rhode Island.

J. Alan Feduccia
Alan Feduccia is a paleornithologist, specializing in the origins and phylogeny of birds. He is the S. K. Henniger Professor at the University of North Carolina. Feduccia's authored works include The Age of Birds and The Origin and Evolution of Birds. Feduccia is best known for his view that birds have their origin not in the advanced theropods, the most widely-held view, but basally within the archosaurs. In recent years Feduccia has become well-known for his opposition to the currently popular dinosaurian origin of birds hypothesis, particularly the ground-up or cursorial origin of flight, and the hypothesis of a very late origin of birds directly from dromaeosaurid theropods. He is currently holds the position of Avian Evolution, Paleobiology and Systematics, Department of Biology, The University of North Carolina at Chapel Hill.

Catherine A. Forster
Her research involves the interpretation of Mesozoic-age fossils, particularly dinosaurs.

Peter M. Galton
Peter M. Galton (born 1942) is a British vertebrate paleontologist working in America, who has to date written or co-written about a hundred papers in scientific journals or chapters in paleontology textbooks, especially on ornithischian and prosauropod dinosaurs. With Robert Bakker in a joint article published in Nature in 1974, he argued that dinosaurs constitute a natural monophyletic group, in contrast to the prevailing view that considered them polyphyletic as consisting of two different not closely related orders, thus initiating a revolution in dinosaur studies and contributing to the revival of the popularity of dinosaurs in the field of paleontology. Peter is Professor Emeritus at University of Bridgeport.

Jacques A. Gauthier
Jacques Armand Gauthier is a vertebrate paleontologist, comparative morphologist, and systematist, and one of the founders of the use of cladistics in biology. Soon after completing his PHD he wrote an important paper on the origin of birds from theropods. This was the first detailed cladistic analysis of the theropod dinosaurs, and initiated a revolution in dinosaur phylogenetics, in which cladistics replaced the Linnaean system in the classification and phylogenetic understanding of the dinosaurs. His is currently Professor, Department of Geology and Geophysics, Yale University.

David D. Gillette
David Gillette is an American paleontologist best known for his discovery of the dinosaur Diplodocus hallorum. At the time of its discovery, Diplodocus was the longest dinosaur known. Gillette found eight huge bones of the Diplodocus in northwestern New Mexico in May 1985. He gave the new dinosaur the name Seismosaurus hallorum, or "earth shaker." The name was later changed, however, to Diplodocus hallorum. David is currently Research Professor, Vertebrate Paleontology , Northern Arizona University.

Walter Granger (PDF)
In 1890, a young Walter Granger began working as a taxidermist at the American Museum of Natural History in New York City. Working in the field with the museum's expeditions in the American West in 1894 and 1895, Granger became interested in hunting fossils. In 1896, he joined the museum's Department of Vertebrate Paleontology and on an expedition to Wyoming, he discovered Bone Cabin Quarry near Laramie. Over the next eight years, the site yielded the fossils of 64 dinosaurs, including specimens of Stegosaurus, Allosaurus and Apatosaurus. In five expeditions between 1922 and 1928 into the Gobi Desert of Mongolia in association with the legendary Roy Chapman Andrews led to Granger's most famous discoveries, including Velociraptor, Oviraptor and Protoceratops, dinosaur finds that the public tended to associate with the more famous Andrews.

William K. Gregory
William King Gregory (19 May 1876 - 29 December 1970) was an American zoologist, renowned as a primatologist, paleontologist, and functional and comparative morphologist. He was an expert on mammalian dentition, and a leading contributor to theories of evolution. In addition he was active in presenting his ideas to students and the general public through books and museum exhibits.

John Bell Hatcher
In 1880 Hatcher became an assistant to Othniel C. Marsh and he excelled in fossil fieldwork throughout the Western states. In 1889 near Lusk, Wyoming Hatcher excavated the first fossil remains of Torosaurus. In 1893 he began a seven-year stint at Princeton University as curator of vertebrate paleontology and assistant in geology. After expeditions to Patagonia and Australia, Hatcher was hired as curator of paleontology and osteology for the Carnegie Museum of Natural History. He was responsible for the scientific investigation and display of Diplodocus carnegii, a species named by Hatcher for his patron Andrew Carnegie (1835–1919), the Scottish-American industrialist. His monograph on the find was published in 1901 as Diplodocus Marsh: Its Osteology, Taxonomy, and Probable Habits, with a Restoration of the Skeleton.

Sydney H. Haughton
Sidney Henry Haughton, (7 May 1888 Bethnal Green, London - 24 May 1982), was an English-born South African paleontologist and geologist. The eldest of three children born to Henry Charles Haughton and Alice Aves, he is best-known for his description of the sauropodomorph dinosaur Melanorosaurus in 1924, and his work on the geology of the Witwatersrand.

Oliver Perry Hay
Oliver Perry Hay (22 May 1846 – 2 November 1930) was an American professor and paleontologist. In 1912, Hay was appointed as a research associate at the Carnegie Institute, and was given office space at the United States National Museum. There he did much work with the USNM's collections in vertebrate paleontology. He published extensively on fossil turtles and Pleistocene mammals. The catalogs that he constructed were a great aid in recording existing knowledge and became standard references. His papers from 1911 to 1930 are stored at the Smithsonian Institution.

He was also consulted as a scientific advisor on the Walking With Dinosaurs BBC series.

James A. Hopson
James Allen Hopson (1935-) is an American paleontologist and professor (now retired) at the University of Chicago. His work has focused on the evolution of the synapsids (a group of amniotes that includes the mammals), and has been focused on the transition from basal synapsids to mammals, from the late Paleozoic through the Mesozoic Eras. He received his doctorate at Chicago in 1965, and worked at Yale before returning to Chicago in 1967 as a faculty member in Anatomy, and has also been a research associate at the Field Museum of Natural History since 1971. He has also worked on the paleobiology of dinosaurs, and his work, along with that of Peter Dodson, has become a foundation piece for the modern understanding of duckbill crests, social behavior, and variation.

John "Jack" R. Horner
John "Jack" R. Horner (born June 15, 1946) is an American paleontologist who discovered and named Maiasaura, providing the first clear evidence that some dinosaurs cared for their young. Horner is best known for his work on the cutting edge of dinosaur growth research and also revitalized the contested theory that Tyrannosaurus rex was an obligate scavenger, rather than a predatory killer. He is one of the best-known paleontologists in the United States. In addition to his many paleontological discoveries, Horner served as the technical advisor for all of the Jurassic Park films, and even served as partial inspiration for one of the lead characters, Dr. Alan Grant. Currently he is working on the developmental biology of dinosaurs as Ameya Preseve Curator of Paleontology, Museum of the Rockies and Regents Professor, Montana State University.

Nicholas Hotton III
Nicholas Hotton III (1920/21–29 November 1999) was an American paleontologist renowned as an expert on dinosaurs and reptiles. He received his Bachelor's Degree in geology and a Ph.D. in paleozoology at the University of Chicago. Dr. Hotton taught anatomy at the University of Kansas from 1951–1959, before joining the staff of the Smithsonian Institution in 1959, initially as an Associate Curator of Vertebrate Paleontology and later as the Curator of Vertebrate Paleontology for the National Museum of Natural History. In addition to administering collections at the National Museum, Dr. Hotton taught a course in vertebrate paleontology at George Washington University. Much of his work focused on dicynodonts, a group of mammal-like reptiles that lived in the Permian and Triassic Periods.

Friedrich von Huene
Friedrich von Huene (Friedrich Freiherr (Baron) Hoyningen) (March 22, 1875 – April 4, 1969) was a German paleontologist who named more dinosaurs in the early 20th century than anyone else in Europe. His discoveries include the skeletons of a herd of more than 35 Plateosaurus that were buried in a mudslide, the early proto-dinosaur Saltopus in 1910, Proceratosaurus in 1926, the giant Antarctosaurus in 1929, and numerous other dinosaurs and fossilized animals like pterosaurs. He also was the first to describe several higher taxa, including Prosauropoda and Sauropodomorpha. Liassaurus huenei, an early carnivorous theropod, was named for him in 1995 though the genus may be invalid.

John Whittaker Hulke
John Whitaker Hulke (6 November 1830 – 19 February 1895) was a British surgeon, geologist and fossil collector. He was the son of a physician in Deal, who became a Huxleyite despite being deeply religious. Hulke became Huxley's colleague at the Royal College of Surgeons. He was a long-time collector from the Wealden cliffs of the Isle of Wight, and his work on vertebrate paleontology included studies of Iguanodon and Hypsilophodon from the Wealden (Lower Cretaceous). He became President of the Geological Society (1882–4); and was awarded Wollaston Medal in 1888.

Adrian P. Hunt
Dr Hunt has published on the stratigraphy, sedimentology, vertebrate paleontology, taphonomy and ichnology of the Fruitland and Kirtland formations. With Spencer Lucas, he has named five of the stratigraphic subdivisions of these units and two of their hadrosaurian dinosaurs (Anasazisaurus and Naashoibitosaurus). Hunt has also published widely on the vertebrate paleontology, ichnology and stratigraphy of the late Paleozoic through late Mesozoic. He is currently a paleontologist and Executive Director of the New Mexico Museum of Natural History and Science, in Albuquerque, New Mexico.

Thomas H. Huxley
Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist, known as Darwin's Bulldog for his advocacy of Charles Darwin's theory of evolution. Huxley's famous 1860 debate with Samuel Wilberforce was a key moment in the wider acceptance of evolution, and in his own career. Huxley was slow to accept some of Darwin's ideas, such as gradualism, and was undecided about natural selection, but despite this he was wholehearted in his public support of Darwin. He was instrumental in developing scientific education in Britain, and fought against the more extreme versions of religious tradition. After comparing Archaeopteryx with Compsognathus, he concluded that birds evolved from small carnivorous dinosaurs, a view widely held today.

Otto Jaekel
Otto Max Johannes Jaekel (February 21, 1863 – March 6, 1929) was a German paleontologist and geologist. As a professor at the University of Greifswald he founded the German Paleontological Society and described a second species of Plateosaurus in 1914.

Sohan L. Jain
Sohan Lal Jain is an Indian paleontologist, who worked for many years at the Indian Statistical Institute, Kolkata. The large herbivorous sauropod dinosaur genus Jainosaurus, was named in his honor after it was identified as a distinct genus. It was earlier thought to be a species of Antarctosaurus. He also made studies of sauropod braincases and some fossil turtles.

Werner Janensch
Ernst Martin Werner Janensch (11 November 1878 - 20 October 1969) was a German paleontologist and geologist. Janensch's most famous contributions stemmed from the expedition he led with Edwin Hennig to the Tendaguru Beds in what is now Tanzania. They recovered at enormous quantity of fossils of late Jurassic period dinosaurs, Including several complete Brachiosaurus skeletons known, then the largest animal ever. Janensch discovered and named several new dinosaur taxa including Dicraeosaurus (1914) and Elaphrosaurus (1920). Janensch's Brachiosaurus finds may belong to a distinct, related genus, Giraffatitan, But this is controversial.

James A. Jensen
James A. Jensen (August 02, 1918 - December 14, 1998), a high-school dropout, became an internationally famous paleontologist. His extensive collecting program at Brigham Young University in the Utah-Colorado region which spanned 23 years was comparable in terms of the number of specimens collected to that of Barnum Brown during the early twentieth century. He was given the name "Dinosaur Jim" during the media coverage of his activities. Perhaps his most significant contribution to paleontology was to replace the 19th Century web of external metal struts, straps and posts that had been used to mount dinosaurs with a system of supports which were placed inside of bones, which produced free-standing skeletons with little or no obvious supports. He assisted Romer and Lewis in mounting the Kronosaurus queenslandicus (1956).

Christopher Johnson

Arthur Lakes
Arthur Lakes (1844–1917) was a notable geologist, artist, writer, teacher and minister. He was a part-time professor at what later became the Colorado School of Mines. Having sent a fossilized vertebra specimen (from the Morrison Formation of Dakota, U.S.) to Othniel Charles Marsh, in 1877, he was then employed by Marsh to seek other discoveries, in the so-called Bone Wars. He went on to unearth fossilized remains of Stegosaurus, Apatosaurus and Allosaurus. Although he was employed by Marsh he also co-operated with Cope. Lakes made the original discovery of the fossils in the formation in Dinosaur Ridge near Morrison, Colorado. The library at the Colorado School of Mines is named for him.

Lawrence M. Lambe
Lawrence Morris Lambe (1849-1934) was a Canadian geologist and palaeontologist from the Geological Survey of Canada (GSC). His published work, describing the diverse and plentiful dinosaur discoveries from the fossil beds in Alberta, did much to bring dinosaurs into the public eye and helped usher in the Golden Age of Dinosaurs in the province. During this period, between the 1880s and World War I, dinosaur hunters from all over the world converged on Alberta. Lambeosaurus, a well-known hadrosaur, was named after him as a tribute, in 1923.

Wann Langston, Jr.
Wann Langston is a professor emeritus in the Jackson School of Geosciences at the University of Texas at Austin. His interest in dinosaurs was kindled early by visits to museums and by the books of Roy Chapman Andrews. In 1954, he succeeded The Grand Old Man of Canadian Dinosaurology, Charles M. Sternberg, as curator at Ottawa's Canadian Museum of Nature. In Canada, Langston's interests focused on the dinosaurs of Alberta and Saskatchewan, and Permian vertebrates of Prince Edward Island. Among his discoveries was a Pachyrhinosaurus bone bed in southern Alberta, which yielded several technical studies over ensuing years. Retired since 1986, he remains active in research at the Texas Memorial Museum's Vertebrate Paleontology Laboratory in Austin. Animals named by Langston include Acrocanthosaurus (1950), the hadrosaurid dinosaur Lophorhothon (1960), and the microsaur Carrolla (1986); the theropod species Saurornitholestes langstoni was named for him.

Albert F. de Lapparent
Albert-Félix de Lapparent (1905 – 1975) was a French palaeontologist. He was also a Jesuit priest. He undertook a number of fossil-hunting explorations in the Sahara desert.

Peter Larson was one of the first to work with T. rex bone pathologies, has worked to uncover sexual dimorphism in the chevron length of T. rex and is considered an overall expert on T. rex fossils.

Joseph Leidy
Leidy named the holotype specimen of Hadrosaurus foulkii, which was recovered from the marl pits of Haddonfield, New Jersey. It was notable for being the first nearly-complete fossilized skeleton of a dinosaur ever recovered. The noted American fossil collector and paleontologist E. D. Cope was a student of Leidy's, but the enmity and ruthless competition that developed between him and rival paleontologist O. C. Marsh eventually drove Leidy out of western American vertebrate paleontology, a field Leidy had helped found. Leidy was an early American supporter of Darwin's theory of evolution, and lobbied successfully for Darwin's election to membership in the Academy of Natural Sciences of Philadelphia.

Guiseppe Leonardi
Italian vertebrate ichnology made a major contribution to vertebrate ichnology through his 1987 publication of the Glossary and Manual of Tetrapod Footprint Palaeoichnology.

Don Lessem

Gideon A. Mantell
Gideon Algernon Mantell MRCS FRS (1790 – 1852) was an English obstetrician, geologist and palaeontologist. His attempts to reconstruct the structure and life of Iguanodon began the scientific study of dinosaurs: in 1822 he was responsible for the discovery (and the eventual identification) of the first fossil teeth, and later much of the skeleton, of Iguanodon. Mantell's work on the Cretaceous of southern England was also important.

Othniel Charles Marsh
Othniel Charles Marsh was born on October 29, 1831 in Lockport, New York. He studied at Yale College, Sheffield Scientific School and in Germany. On returning to the United States he was appointed a professor at Yale University and established the Peabody Museum of Natural History. During the Late 19th Century he became embroiled in the famous "Bone Wars" with Edward Drinker Cope. Ferocious rivals, these two men fought over the discovery and describing of new dinosaur species. Between them Marsh and Cope named over 120 dinosaur species.

Robert M. Sullivan
Robert M. Sullivan was born in New York City and raised in Connecticut. Visits to the Yale Peabody Museum as a child inspired him to become a vertebrate paleontologist. He received his B.A. in geology from the University of New Mexico (1973), completed a year of post-baccalaureate study at the University of Nebraska-Lincoln (1974), received a M.S. in vertebrate paleontology from San Diego State University (1978) and a Ph.D. in geology from Michigan State University (1980). Dr. Sullivan's research interests are in the specialized field of paleoherpetology (the study of fossil amphibians and reptiles). He has focused primarily on the study of the phylogenetic systematics of fossil lizards and dinosaurs, Late Creataceous biochronology, as well as the controversial topic of dinosaur extinction. Since 1979 he has been actively pursuing fieldwork in New Mexico, concentrating his collecting efforts in the San Juan Basin, targeting the Fruitland, Kirtland, Ojo Alamo and Nacimiento formations for non-mammalian fossil vertebrates. Some of his more noteworthy discoveries include a new specimen of the rare lambeosaurine dinosaur Parasaurolophus tubicen (the second and most complete specimen known of the genus) and a new ankylosaurid dinosaur Nodocephalosaurus kirtlandensis, which he named in 1999. In 2003, he and colleague Dr. Spencer G. Lucas, defined the “Kirtlandian” a new land-vertebrate age for the Late Cretaceous of western North America. In recent years he has become the leading authority on pachycephalosaurid dinosaurs and has published a number of papers on these enigmatic ornithischians. Named/co-named dinosaur taxa: Aguaceratops (2006), Alaskacephale (2006), Camposaurus (1997), Caseosaurus (1997), Colepiocephale (2003), Dracorex (2006), Eucoelophysis (1999), Hanssuesia (2003), Nodocephalosaurus (1999), and Ojoceratops (2010).
