John Bell Hatcher was an American paleontologist and fossil hunter known as the "king of collectors" and best known for discovering Torosaurus and Triceratops, two genera of dinosaurs described by Othniel Charles Marsh. He was part of a new, professional middle class in American science, having financed his education with his labor while also being more educated than older fossil collectors. As such, he faced unique challenges throughout his long and productive career.
Annie Montague Alexander was an explorer, naturalist, paleontological collector, and philanthropist.
John Campbell Merriam was an American paleontologist, educator, and conservationist. The first vertebrate paleontologist on the West Coast of the United States, he is best known for his taxonomy of vertebrate fossils at the La Brea Tar Pits in Los Angeles, particularly with the genus Smilodon, more commonly known as the sabertooth cat. He is also known for his work to extend the reach of the National Park Service.
Karl Hermann Konrad Burmeister was a German Argentine zoologist, entomologist, herpetologist, botanist, and coleopterologist. He served as a professor at the University of Halle, headed the museum there and published the Handbuch der Entomologie (1832–1855) before moving to Argentina where he worked until his death.
Charles Hazelius Sternberg was an American fossil collector and paleontologist. He was active in both fields from 1876 to 1928, and collected fossils for Edward Drinker Cope and Othniel C. Marsh, and for the British Museum, the San Diego Natural History Museum and other museums.
Ynés Enriquetta Julietta Mexía was a Mexican-American botanist notable for her extensive collection of novel specimens of flora and plants originating from sites in Colombia, Mexico, and Peru. She discovered a new genus of Asteraceae, known after her as Mexianthus, and accumulated over 150,000 specimens for botanical study over the course of a career spanning 16 years enduring challenges in the field that included poisonous berries, dangerous terrain, bogs and earthquakes for the sake of her research.
The Journey Museum and Learning Center is a museum in Rapid City, South Dakota, United States with 7 acres (28,000 m2) of gardens. It is set up as a journey through the history of the Black Hills, starting with the Native American creation stories, moving into the 2.5 billion years of history in the rock record with the geology exhibit, paleontology, archaeology, Native American inhabitants, and concluding with the pioneers that traveled west.
Scelidotherium is an extinct genus of ground sloth of the family Scelidotheriidae, endemic to South America during the Late Pleistocene epoch. It lived from 780,000 to 11,000 years ago, existing for approximately 0.67 million years.
Walter Willis Granger was an American vertebrate paleontologist who participated in important fossil explorations in the United States, Egypt, China and Mongolia.
Leonard John Brass was an Australian and American botanist, botanical collector and explorer.
Colin James Oliver Harrison was an English ornithologist.
Darren H. Tanke is a Canadian fossil preparation technician of the Dinosaur Research Program at the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta. Born in Calgary, Tanke became interested in natural history at an early age. In 1979, Tanke began working for Philip J. Currie in the paleontology department of the Provincial Museum of Alberta, originally as a volunteer. From 1979 until 2005 Tanke worked as a lab and field technician, a job he still holds today.
Andrewsornis is an extinct genus of giant flightless predatory birds of the family Phorusrhacidae or "terror birds" that lived in Oligocene Argentina. Fossils have been found in the Sarmiento Formation, and possibly the Agua de la Piedra Formation.
The Bernardino Rivadavia Natural Sciences Argentine Museum is a public museum located in the Caballito section of Buenos Aires, Argentina.
Elmer Samuel Riggs was an American paleontologist known for his work with the Field Museum of Natural History in Chicago, Illinois.
Robert Coin Thorne was an American paleontologist.
The Captain Marshall Field Expeditions were undertaken by the Field Museum of Natural History in Chicago, Illinois. The two Captain Marshall Field paleontological expeditions had the goal of finding South American Cenozoic mammals. The mammals of South America had evolved in near total isolation from the rest of the world from almost the beginning of the Cenozoic Era until only a few million years ago.
Bryan Patterson was an American paleontologist at the Field Museum of Natural History in Chicago.
Paleontology in South Dakota refers to paleontological research occurring within or conducted by people from the U.S. state of South Dakota. South Dakota is an excellent source of fossils as finds have been widespread throughout the state. During the early Paleozoic era South Dakota was submerged by a shallow sea that would come to be home to creatures like brachiopods, cephalopods, corals, and ostracoderms. Local sea levels rose and fall during the Carboniferous and the sea left completely during the Permian. During the Triassic, the state became a coastal plain, but by the Jurassic it was under a sea where ammonites lived. Cretaceous South Dakota was also covered by a sea that was home to mosasaurs. The sea remained in place after the start of the Cenozoic before giving way to a terrestrial mammal fauna including the camel Poebrotherium, three-toed horses, rhinoceroses, saber-toothed cat, and titanotheres. During the Ice Age glaciers entered the state, which was home to mammoths and mastodons. Local Native Americans interpreted fossils as the remains of the water monster Unktehi and used bits of Baculites shells in magic rituals to summon buffalo herds. Local fossils came to the attention of formally trained scientists with the Lewis and Clark expedition. The Cretaceous horned dinosaur Triceratops horridus is the South Dakota state fossil.
Santiago Roth was a Swiss Argentine paleontologist and academic known for his fossil collections and Patagonian expeditions.
