That's right, kids, the world's most captivating crea- tures, those marvelous megafauna from the Mesozoic, the greatest attractions in all of natural history, are returning to the spotlight.

Kurzanov A NEW CARNOSAUR FROM THE LATE CRETACEOUS OF NOGON-TSAV, MONGOLIA* The Upper Cretaceous locality of Nogon-Tsav, located in the Zaltaika Gobi, 20 km NW of Mt. Ongon-Ulan-Ula, was discovered by geologists of the MNR. Then, in a series of years (1969–1971, 1973) the joint Soviet-Mongolian Geological Expedition investigated the site. According to the oral report of B. Yu. Reshetova, the deposits in this region are composed basically of sandstone and clay, clearly subdivided into two deposits. The lower great thickness contains many complete skulls, separate bones of tarbosaurs, ornithomimids, and claws of therizinosaurs. The upper red-colored beds are characterized only by scattered fragments of skulls. The fragments described below are of a new carnivorous dinosaur, Alioramus remotus (coll. South Goby region), from the family Tyrannosauridae, which occurs in the lower gray beds. Genus Alioramus Kurzanov, gen. nov. G e n u s n a m e from alius (Lat.) – other, ramus (Lat.) – branch; masc.

Rivadavia 1917 - Cdad. de Buenos Aires, Argentina (Received 28 November 2008; revised 09 July 2009; accepted 14 July 2009) ABSTRACT The oldest unequivocal records of Dinosauria were unearthed from Late Triassic rocks (approximately 230 Ma) accumulated over extensional rift basins in southwestern Pangea. The better known of these are Herrerasaurus ischigualastensis, Pisanosaurus mertii, Eoraptor lunensis,andPanphagia protos from the Ischigualasto Formation, Argentina, and Staurikosaurus pricei and Saturnalia tupiniquim from the Santa Maria Formation, Brazil. No uncontroversial dinosaur body fossils are known from older strata, but the Middle Triassic origin of the lineage may be inferred from both the footprint record and its sister-group relation to Ladinian basal dinosauromorphs. These include the typical Marasuchus lilloensis, more basal forms such as Lagerpeton and Dromomeron, as well as silesaurids: a possibly monophyletic group composed of Mid-Late Triassic forms that may represent immediate sister taxa to dinosaurs. The first phylogenetic definition to fit the current understanding of Dinosauria as a node-based taxon solely composed of mutually exclusive Saurischia and Ornithischia was given as ‘‘all descendants of the most recent common ancestor of birds and Triceratops’’.

  • 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.
