Marsh1,2 and Timothy B. Rowe1 1Jackson School of Geosciences, the University of Texas at Austin, 2305 Speedway Stop C1160, Austin, Texas 78712, USA <[email protected]><[email protected]> 2Division of Resource Management, Petrified Forest National Park, 1 Park Road #2217, Petrified Forest, Arizona 86028, USA Abstract.—Dilophosaurus wetherilli was the largest animal known to have lived on land in North America during the Early Jurassic. Despite its charismatic presence in pop culture and dinosaurian phylogenetic analyses, major aspects of the skeletal anatomy, taxonomy, ontogeny, and evolutionary relationships of this dinosaur remain unknown. Skeletons of this species were collected from the middle and lower part of the Kayenta Formation in the Navajo Nation in northern Arizona. Redescription of the holotype, referred, and previously undescribed specimens of Dilophosaurus wetherilli supports the existence of a single species of crested, large-bodied theropod in the Kayenta Formation. The parasagittal nasolacrimal crests are uniquely constructed by a small ridge on the nasal process of the premaxilla, dorsoventrally expanded nasal, and tall lacrimal that includes a posterior process behind the eye. -

The Origin and Early Evolution of Dinosaurs

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’’. -

Gideon Mantell, a 19th century British palaeontologist, made a less flattering remark when he wrote in his journal, “… sallied out in quest of Mary An- ning, the geological lioness … we found her in a little dirt shop with hundreds of specimens piled around her in the greatest disorder. She, the presiding Deity, a prim, pedantic vinegar looking female; shred, and rather satirical in her conversation” (Curwin, 1940).

ZOOLOGY Exploring the Biodiversity of Colorado and Theworld
CHAPTER 4 — ZOOLOGY Exploring the Biodiversity of Colorado and the World CHAPTER 4 ZOOLOGY Exploring the Biodiversity of Colorado and the World Jeffrey T. Stephenson, Before the Museum Paula E. Cushing, The first collections of specimens that make up what is now the Denver John R. Demboski, and Museum of Nature & Science were actually established well before the Frank-T. Krell founding of the institution in 1900, the selection of a board of trustees, or the construction of a building to house and exhibit the specimens. Edwin Carter (1830–1900) (Fig. 4.1) collected Colorado birds and mammals from the 1860s through the 1890s. Born in New York in 1830, Carter arrived in Colorado in 1859 hoping to make it rich in the goldfields, but he soon became interested in the region’s natural history. He learned hide tanning and, as his prospects for hitting the mother lode faded, he earned his living selling buckskin clothing that he handcrafted. Carter supplemented these earnings by mar- keting foodstuffs and other provisions to the growing population of successful and (mostly) unsuccessful prospectors flooding the region. His interest in nature turned to concern as he observed dwindling numbers of mammals and birds, owing largely to habitat destruction and overhunting. Period photographs of the area’s mining district show a landscape largely denuded of vegetation. By the 1870s, Carter noted that many animal species were becoming scarce. The state’s forests were being devastated, ranches and farms were replacing open prairie, and some species, including the last native bison in Colorado, were on the verge of extirpation or extinction. -

The portrait includes the fossil cliffs of Lyme Bay in the background. Mary is pointing at an ammonite, with her companion Tray dutifully curled beside the ammonite protecting the find. The portrait eventually became the property of Joseph, Mary‟s brother, and in 1935, was presented to the Geology Department, British Museum, by Mary‟s great-great niece Annette Anning (1876-1938). The portrait is now in the Earth Sciences Library, British Museum of Natural History. A similar portrait in pastels by B.J.M. Donne, hangs in the entry hall of the Geological Society of London. -

Wedel1*, Michael P. Taylor2* 1 College of Osteopathic Medicine of the Pacific and College of Podiatric Medicine, Western University of Health Sciences, Pomona, California, United States of America, 2 Department of Earth Sciences, University of Bristol, United Kingdom Abstract Skeletal pneumaticity is found in the presacral vertebrae of most sauropod dinosaurs, but pneumaticity is much less common in the vertebrae of the tail. We describe previously unrecognized pneumatic fossae in the mid-caudal vertebrae of specimens of Giraffatitan and Apatosaurus. In both taxa, the most distal pneumatic vertebrae are separated from other pneumatic vertebrae by sequences of three to seven apneumatic vertebrae. Caudal pneumaticity is not prominent in most individuals of either of these taxa, and its unpredictable development means that it may be more widespread than previously recognised within Sauropoda and elsewhere in Saurischia.
