1 Lecture 1. Introduction to Dinosaur Studies 4000 YEARS OF 1 Lecture 1. Introduction to Dinosaur Studies 4000 YEARS OF MADNESS DARK AGES: MYTHICAL AND OTHER EARLY VIEWS Dragon bones in China Dinosaur teeth and bones collected ~1500 BC in China Ground into medicine Chinese dragons typically wingless, some serpent-like Dragon bones in the West Western dragons tend to be winged, perhaps because pterosaur fossils more common on mainland Europe than dinosaurs. Are mythic Griffins based on Protoceratops Herodotus hunting for flying snakes in Egypt (~430 BC) Robert Plot - 1676: First illustration of a dinosaur bone. Thought it was the leg of giant human "Scrotum humanum"? AGE OF ENLIGHTENMENT Mary Anning (1799-1847) - Great Victorian fossil collector. Pterosaurs, ichthyosaurs, plesiosaurs William Buckland (1784-1856) - 1824, first paper describing dinosaurs as extinct giant reptile. Megalosaurus (carnosaur) Reconstructed as a giant Komodo dragon. Gideon Mantell - 1825, second paper describing a dinosaur, Iguanodon (duck-billed dinosaur). Richard Owen (1804-1892) - brilliant anatomist. Coined the term Dinosauria for these 'fearfully great lizards' in April, 1842. Defined as having teeth set in bony sockets, large sacra composed of five fused vertebrae, ribs with two heads, a complex shoulder girdle, long hollow limb bones and mammal-like feet. He thought all dinos were a group of advanced reptiles, and that all were quadrupeds. Because the first identified dinosaurs were large and because they were clearly reptiles, scientists misunderstood them for a long time. If first dinosaurs identified had been smaller bird-like forms the history of dinosaur science might have been much different. DINOMANIA I 1850s - Crystal Palace and Benjamin Waterhouse Hawkins: dinosaur paintings and life- size sculptures. Owen was in charge of project. He collaborated w/ sculptor Waterhouse Hawkins. Reconstructions portrayed dinos as awkward, lizard-like, quadrupedal, but no complete skeletons found to this point. 1850-1860: First complete dinosaur skeletons found and described: Owen in England (quadruped); Leidy in America (bipedal). DINOMANIA PART II Harry Govier Seely - 1887 - Bird vs. lizard-hipped dinosaurs Cope and Marsh Feud - 1860-1890 - Most of the famous dinosaurs from North America were collected in a frenzy of activity from 1870 to 1900, spurred by intense rivalry between two men: Edward Cope and Othniel Marsh. Their prime hunting ground: Colorado, Wyoming, Montana. Como Bluff. Bone Cabin Quarry one of richest sites, local trapper built a cabin made of dinosaur bones. Originally Cope and Marsh 2 were friends (Cope from wealthy quaker family, worked at Philadelphia Academy of Sciences; Marsh used his uncle Peabody's $ to fund Yale Peabody Museum, his own endowed teaching position and to fund expeditions). Feud began with competition for best sites and with Marsh's published expose of a misreconstructed Elasmosaurus by Cope (head at wrong end). Marsh also bribed Cope's collectors to send him new fossils from their pits. Both Cope and Marsh used collectors to get most fossils. Their competition greatly increased the popularity of dinosaurs in America; unfortunately in their haste their collectors sometimes destroyed and damaged specimens AND it resulted in termination of federal funding for their work AND for the US Geological survey. Also, Marsh dynomited some excavations in Wyoming that Cope claimed were his. On one occasion, Cope had a train load of Marsh's specimens diverted to Philadelphia. Many famous dinos discovered and named during this period, including Allosaurus, Ceratosaurus, Apatosaurus, Diplodocus, Stegosaurus and Triceratops. On Marsh's first expedition in 1870 Wm. F. Cody (Buffalo Bill) acted as a guide for the first leg of the trip. He remained a life long friend of Marsh. Both Cope and Marsh exhausted their personal fortunes as a result of the bone wars. Turn of the century Dinosaur Rush: Henry Fairfield Osborn - 1857-1935: American Museum. Barnum Brown - 1873-1963: A life-long employee of the American Museum in New York. Charles Sternberg - 1850-1943: fossil collector and amateur DINOMANIA III - World wide exploration through the 20th century Werner Janensch - Tanzania and Ernst Stomer - Egypt Roy Champan Andrews - Mongolia in the 1920s - dinosaur eggs Antarctic expeditions in the 1990s DINOMANIA IV - Dinosaur renaissance Dinosaurs in the seat of government Many new theories and new ideas about ecology, physiology, behavior and evolution Much new blood .

    VoL. 6, 1920 PALAEONTOLOGY: OSBORN AND MOOK IS RECONSTRUCTION OF THE SKELETON OF THE SAUROPOD DINOSAUR CAMARASA URUS COPE (MOROSA URUS MARSH) By HENRY FAIRFIELD OSBORN AND CHARLES CRAIG MOOK AMERICAN MusEUM or NATURAL HISTORY, NEW YORK CITY Read before the Academy, November 11, 1919 The principles of modern research in vertebrate palaeontology are illustrated in the fifteen years' work resulting in the restoration of the massive sauropod dinosaur known as Camarasaurus, the "chambered saurian.." The animal was found near Canyon City, Colorado, in March, 1877. The first bones were described by Cope, August 23, 1877. The first at- tempted restoration was by Ryder, December 21, 1877. The bones analyzed by this research were found probably to belong to six individuals of Camarasaurus mingled with the remains of some carnivorous dinosaurs, all from the summit of the Morrison formation, now regarded as of Jurassic- Cretaceous age. In these two quarries Cope named nine new genera and fourteen new species of dinosaurs, none of which have found their way into. palaeontologic literature, excepting Camarasaurus. Out of these twenty-three names we unravel three genera, namely: One species of Camarasaurus, identical with Morosaurus Marsh. One species of Amphicaclias, close to Diplodocus Marsh. One species of Epanterias, close to Allosaurus Marsh. The working out of the Camarasaurus skeleton results in both the artica ulated restoration and the restoration of the musculature. The following are the principal characters: The neck is very flexible; anterior vertebrae of the back also freely movable; the division between the latter and the relatively rigid posterior dorsals is sharp.

  • Robert Plot (1641—1696)
    ( 218 ) SOME EARLY BRITISH ORNITHOLOGISTS AND THEIR WORKS. BY W. H. MULLENS, SI.A., LL.M., M.B.O.U. V.—ROBERT PLOT (1641—1696) AND SOME EARLY COUNTY NATURAL HISTORIES. IN the year 1661, Joshua Childrey (1623—1670), antiquary, schoolmaster, and divine, published in London a small duodecimo work entitled " Britannia Baconia: / or, the Natural / Rarities / of / England, Scotland, & Wales." This book, although of no particular value in itself, being merely a brief and somewhat imperfect compilation, was nevertheless destined to be of some considerable influence on the literature of natural history in this country. For, according to Wood's " Athense Oxonienses" (p. 339), it inspired Robert Plot (1641—1696), the first keeper of the Ashmolean Museum at Oxford, with the idea of writing the " Natural History of Oxfordshire," which appeared in 1677, and which was followed in 1686 by a " Natural History of Staffordshire," the work of the same author ; who is said to have also contemplated similar histories of Middlesex and Kent. These two works of Robert Plot's also proved in their turn to be the forerunners of a numerous series of county natural histories by different writers. The full title of the " Natural History of Oxfordshire" is as follows :— " The / Natural History / of / Oxford-shire, / being an Essay toward the Natural History / of / England. / By R.P., LL.D. / [quotation from Arat. in Phsenom.] / [engraving] Printed at the Theater in Oxford, and are to be had there: / And in London at Mr. S. Millers, at the Star near the / West-end of SOME EARLY BRITISH ORNITHOLOGISTS.

FIFTY1NINTH ANNUAL REPORT OF THE TRUSTEES FOR THE YEAR 1927 - THE AMERICAN MUSEUM OF NATURAL HISTORY IHE CITY OF NEW YORK Issued May 1, 1928 BUILDING THE AMERICAN MUSEUM 1869-1927 PRESIDENT HENRY FAIRFIELD OSBORN And David said to Solomon his son, "Be strong and of good courage, and do it; fear not, nor be dismayed: for the Lord God, even my God, uill be with thee; he will not fail thee, nor forsake thee, until thou hast finished all the work for the service of the house of the Lord."-Chronicles I, XXVIII. In 1869, Albert S. Bickmore, a young naturalist of the State of Maine, projected this great Museum. First advised by Sir Richard Owen, Director of the British Museum, the plans for the building grew by the year 1875 into the titanic dimensions plotted by Frederick Law Olmsted, designer of Central Park. The approaching sixtieth anniversary of our foundation, on April 6, 1929, will witness the construction of fourteen out of the twenty-one building sections planned by Professor Albert S. Bickmore and Mr. Frederick L-aw Olmsted. With strength and courage, the seventieth anniversary, April 6, 1939, will witness the completion of the Museum building according to the plan set forth in this Report.

  • Natural History of Staffordshire Printed in Oxford in 1686, the Subject of This Article
    THE NATURAL HISTORY OF STAFFORD-SHIRE. By Robert Plot, LLD. Keeper of the Ashmolean Musæum and Professor of Chymistry in the University of Oxford. Ye shall Describe the Land, and bring the Description hither to Me. Joshua 8. v. 6. Oxford printed at the Theatre, Anno M. DC. LXXXVI. (1686) by Yasha Beresiner Introduction This volume, now in the Masonic Library of the Regular Grand Lodge of Italy, contains the earliest recorded account of accepted masonry and is considered the most implicit report on the fraternity available for the period at the end of the 17th century. It is printed in paragraphs 85 to 88 inclusive, on pages 316 to 318 of the tome. This text is referred to as the Plot Abstract. Its importance lies a) with regard to its content i.e. the summary of the legendary history, the description of contemporary freemasonry, and the criticisms of the fraternity and b) as to the sources from which Plot may have derived his information, most importantly, what he refers to as the ‘large parchment volum they have amongst them . .’ The purpose of this article is not to analyse the text and its content but rather to identify and clarify the reasons behind the importance of this Volume in the context of Masonic bibliography and history. Robert Plot Robert Plot (1640-96) was born in Kent and received a BA degree from Oxford University in 1661, an MA in 1664 and a Law degrees in 1671. In 1677 he was elected a Fellow of the Royal Society and became Secretary in 1682.

  • MEMORIAL to BARNUM BROWN (1873-1963) G. EDWARD LEWIS U. S. Geological Survey, Denver, Colorado Barnum Brown, the Last and Most S
    MEMORIAL TO BARNUM BROWN (1873-1963) G. EDWARD LEWIS U. S. Geological Survey, Denver, Colorado Barnum Brown, the last and most successful of the great fossil hunters who led expeditions to the far corners of the earth during the Golden Age of vertebrate paleontological exploration, died on 5 February, 1963. Nothing short of a book would be adequate to do justice to this remarkable man's full life, his explora- tions, and other scientific achievements: he was associated with the American Museum of Natural History in New York from 1897 to 1963; although he did not explore the South Sea Islands, Madagas- car, or the Antipodes, he ranged far and wide over the major continents of the world and covered vast areas literally step by step. Barnum's parents were of old American stock: William Brown was a Virginian, born in 1833, who travelled westward to Wisconsin, where he married Clara Silver near Monticello, where she was born in 1840. They loaded their possessions into an ox-drawn covered wagon in 1859 and headed westward with their first child, Clara Melissa. They averaged 10 miles a day on the way to Kansas Territory where, near Lickskillet in Osage County, a second daughter, Alice Elizabeth, was born on 4 January 1860. Nearby in the same county was a place underlain by coal where they built a one-room cabin on Carbon Hill, to the west of which Carbondale sprang up some years later. The cabin doors were closed by flaps of canvas; the windows were covered with greased paper; there were cots, packing boxes, and barrel chairs for furniture.
