>History of the Dinosaur Collection
The offset pregnant dinosaur fossils added to the museum’s collections were the type specimen of the sauropod Dystrophaeus viaemalae, collected past times J. S. Newberry in addition to donated inwards 1859, in addition to Lower Jurassic dinosaur footprints from the Connecticut Valley, donated inwards 1861. These fossils were catalogued along with all other vertebrates inwards the Department of Osteology. It was non until 1887 that the Department of Vertebrate Fossils was established, in addition to given its ain catalogue system. The acronym for the “U. S. National Museum” (USNM) became purpose of our official designation for specimen catalogue numbers, in addition to remains therefore fifty-fifty though our cite has been changed to the National Museum of Natural History.
The honorary caput curator of this novel subdivision was the famous dinosaur paleontologist O. C. Marsh of Yale University, in addition to he was assisted past times Frederic Lucas, who was based inwards Washington, D.C. Marsh led active plain expeditions for both Yale University in addition to the U. S. Geological Survey. During Marsh’s lifetime, these fossils were reposited at Yale, but upon his expiry inwards 1899, all the vertebrate fossils he had collected for the authorities (over lxxx tons!) were transferred to the Smithsonian Institution. Marsh’s collections include or therefore of the nearly of import dinosaurs known to science, amid them our demo specimens of Allosaurus, Stegosaurus, Camptosaurus, Ceratosaurus, Triceratops, in addition to Edmontosaurus. The “Marsh Collection” all the same constitutes the largest unmarried dinosaur collection at the Smithsonian.
In 1898, J. W. Coleman was hired every bit the offset full-time preparator of vertebrate fossils. He was joined inwards 1900 past times Alban Stewart. They shortly left authorities service in addition to were replaced past times Charles W. Gilmore (1903), Norman H. Boss (1904) , in addition to James W. Gidley (1905). In 1908, Gilmore was promoted to Custodian of Fossil Reptiles, in addition to inwards 1924 he was 1 time again promoted to the rank of Curator. While at the Smithsonian, Gilmore became 1 of the nearly renowned vertebrate paleontologists of the twentieth century, in addition to with him Norman Boss mounted nearly of the museum’s famous dinosaur exhibits.
Gilmore led xvi dinosaur expeditions during his tenure every bit Curator, to a greater extent than frequently than non to Wyoming in addition to Utah, in addition to the collections he brought dorsum to the Smithsonian Institution included Diplodocus, Camarasaurus, in addition to Brachyceratops. He also studied the Marsh Collection extensively, producing of import studies of the dinosaurs Camptosaurus, Allosaurus, Ceratosaurus, Stegosaurus, in addition to Thescelosaurus. The offset complete, fully mounted dinosaurs to live exhibited past times Gilmore in addition to Boss were Edmontosaurus inwards 1903, followed past times Triceratops inwards 1905, both inwards the Arts in addition to Industries Building.
The Establishment of the Smithsonian Institution
In 1846 Congress established the Smithsonian Institution, an organization dedicated to the “...increase in addition to diffusion of knowledge.” At this fourth dimension Congress transferred the National Cabinet of Curiosities to the nascent institution. Part of the human activeness of Congress that created the Smithsonian also mandated that “...all of objects of natural history, plants, in addition to geological in addition to mineralogical specimens belonging or future to belong to the United States” would operate the holding of the Smithsonian Institution. This made it a Trust Entity, to human activeness on behalf of the U.S. every bit the national treasury for its official objects. The Institution’s offset building, normally known every bit “The Castle”, was completed inwards 1855, in addition to housed all Smithsonian operations in addition to collections.
In 1879 the Sundry Civil Act farther expanded the role of the Institution therefore that “...all collections of rocks, minerals, soils, fossils, in addition to objects of natural history, archaeology, in addition to ethnology, made past times the Coast in addition to Interior Survey, the Geological Survey, or past times whatsoever other parties for the authorities of the United States, when no longer needed for investigations inwards progress, shall live deposited inwards the National Museum.” The Arts in addition to Industries edifice has the especial designation every bit the master copy U.S. National Museum. This edifice opened inwards 1881 in addition to was the dwelling identify of the offset exhibition of the Section of Vertebrate Paleontology.
Prior to 1870, many of the early on vertebrate fossils collected past times the Smithsonian in addition to other authorities agencies were sent to Dr. Joseph Leidy inwards Philadelphia. Leidy is considered to live the “father” of American vertebrate paleontology for the United States, in addition to described many of the offset dinosaur fossils found inwards the United States. His nearly famous uncovering was that of the hadrosaurid Hadrosaurus, at Haddonfield, New Jersey. As the offset dinosaur skeleton found inwards the U. S., it formed the reason for a full-scale model past times sculptor Waterhouse Hawkins. One such model stood inwards the Smithsonian’s offset paleontological exhibit, with a model of the dry reason sloth Megalonyx.
The New U.S. National Museum
In 1910, the electrical flow U. S. National Museum (USNM) opened on the N side of the National Mall. The dinosaur collections were moved across the mall to this novel museum, where they accept been housed e'er since. The mounts of Edmontosaurus in addition to Triceratops were also relocated to operate purpose of the novel Hall of Extinct Monsters. There they were joined past times novel mounts of Ceratosaurus (1910), Camptosaurus (1911), 2 individuals of Stegosaurus (1913 in addition to 1918), Thescelosaurus (1914), Brachyceratops (1920), in addition to Diplodocus (1931). The Diplodocus skeleton was lxx feet long, in addition to visitors were allowed to walk underneath the skeleton, making it the nearly pop demo for over 20 years.
With Gilmore’s retirement inwards 1945, the seat of Curator of Lower Vertebrates was filled for the offset fourth dimension past times a Ph.D. inwards vertebrate paleontology, Charles Gazin (whose specialty was Cenozoic vertebrates, non dinosaurs). If fact, betwixt 1941 in addition to 2003 the USNM (now the National Museum of Natural History) hired half-dozen curators inwards vertebrate paleontology, none of whom specialized inwards dinosaurs.
One of these curators, Nicholas Hotton III, undertook the offset major renovation of the dinosaur hall inwards the early on 1960s. This hall utilized all the existing mounts in addition to added 1 more, the specimen of Gorgosaurus (completed inwards 1960) currently exhibited on the N wall. Although nearly of the dinosaur skeletons were unchanged, the hall itself was substantially redesigned in addition to reorganized. This hall opened to Earth inwards 1963, in addition to patch the visiting world was no longer allowed to walk nether the Diplodocus, in that location was straight off a sauropod femur that they were allowed to touch.
The hall shut 1 time again inwards 1979 every bit planning began for a novel hall that would highlight the museum’s collections every bit purpose of “Fossils: The History of Life”. Again, all of the existing dinosaur mounts were kept, but rearranged to suit the novel pattern of the exhibit. One novel mount, Allosaurus, was constructed in addition to integrated into a key demo of Late Jurassic dinosaurs. This novel hall was opened inwards December,1981, in addition to remains the centerpiece of the Smithsonian’s paleontology exhibit.
Modern Times at the National Museum of Natural History
Since then, 2 of our demo specimens accept been removed for conservation. After nearly a century of exhibition, many of the dinosaur bones had begun to fissure due to the noise from millions of visitors in addition to the cracking changes inwards ambient humidity. Without replacement, the specimens may accept undergone a “second extinction.” In 2000, the Triceratops mountain was the offset to live conserved, in addition to the master copy bones were repaired in addition to placed inwards the collections. The mounted skeleton was replaced past times plaster casts, straight off inwards a to a greater extent than scientifically accurate pose. In 2003 our Stegosaurus was also conserved in addition to replaced with a mountain that was designed to live responsive to the Allosaurus straight behind it. In 2004 nosotros start out the same procedure on our Camptosaurus, which volition supply to display inwards 2005.
In add-on to demo additions in addition to changes, dinosaur query inwards dinosaur paleontology has undergone a revitalization inwards the final xxx years. In 1979 the Smithsonian Institution hired Michael K. Brett-Surman every bit a Collections Specialist, in addition to inwards 1988 he became the offset Smithsonian employee to obtain a Ph.D. inwards dinosaur paleontology. In 1992 the offset of a serial of novel dinosaur expeditions was begun, to the Big Horn Basin inwards Wyoming. These novel collections include dinosaur footprints (Jurassic), bones (Jurassic in addition to Cretaceous), in addition to eggshells (Jurassic).
In 2003 the Smithsonian Institution hired Dr. Matthew T. Carrano every bit its offset dinosaur specialist since Gilmore’s time, in addition to its offset official Curator of Dinosaurs. He late led expeditions to the Big Horn Basin of Wyoming to collect Late Jurassic in addition to Early Cretaceous dinosaurs, every bit good every bit to the Cretaceous deposits of Madagascar.
