R. Cannell ABSTRACT abdomen as well as spiny and surprisingly robust legs. Illustrations An engineering examination of allometric and analogical data on the of M. monyi and a female Meganeurula selysii (Shear and flight of giant Permian insects (Protodonata, Meganeura or griffinflies) Kukalova-Peck, 1990) also indicate creatures with strong mouth indicates that previous estimates of the body mass of these insects parts, well-developed pincers and strong long thick legs. In both are too low and that the largest of these insects (wingspan of 70 cm or drawings, the abdomen is similar in diameter to the thorax, unlike more) would have had a mass of 100–150 g, several times greater the structure of most modern dragonflies, which have much more – – than previously thought. Here, the power needed to generate lift and slender abdomens. This large size and consequently high mass fly at the speeds typical of modern large dragonflies is examined has attracted attention for over a hundred years as there are no extant together with the metabolic rate and subsequent heat generated by insects of this size and their physiology in terms of power generation the thoracic muscles. This evaluation agrees with previous work and thermoregulation is not understood. This Commentary suggesting that the larger specimens would rapidly overheat in the examines the questions of mass, power generation to fly and high ambient temperatures assumed in the Permian. -

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’’. -

The Largest Tropical Peat Mires in Earth History
Geological Society of America Special Paper 370 2003 Desmoinesian coal beds of the Eastern Interior and surrounding basins: The largest tropical peat mires in Earth history Stephen F. Greb William M. Andrews Cortland F. Eble Kentucky Geological Survey, University of Kentucky, Lexington, Kentucky 40506, USA William DiMichele Smithsonian Institution, National Museum of Natural History, Washington, D.C., USA C. Blaine Cecil U.S. Geological Survey, Reston, Virginia, USA James C. Hower Center for Applied Energy Research, University of Kentucky, Lexington, Kentucky, USA ABSTRACT The Colchester, Springfield, and Herrin Coals of the Eastern Interior Basin are some of the most extensive coal beds in North America, if not the world. The Colchester covers an area of more than 100,000 km^, the Springfield covers 73,500-81,000 km^, and the Herrin spans 73,900 km^. Each has correlatives in the Western Interior Basin, such that their entire regional extent varies from 116,000 km^to 200,000 km^. Correlatives in the Appalachian Basin may indicate an even more widespread area of Desmoinesian peatland development, although possibly sUghtly younger in age. The Colchester Coal is thin, but the Springfield and Herrin Coals reach thicknesses in excess of 3 m. High ash yields, dominance of vitrinite macerals, and abundant lycopsids suggest that these Desmoinesian coals were deposited in topogenous (groundwater fed) to solige- nous (mixed-water source) mires. The only modern mire complexes that are as wide- spread are northern-latitude raised-bog mires, but Desmoinesian -
Why Much of What We Teach About Evolution Is Wrong/By Jonathan Wells
ON SCIENCE OR MYTH? Whymuch of what we teach about evolution is wrong Icons ofEvolution About the Author Jonathan Wells is no stranger to controversy. After spending two years in the U.S. Ar my from 1964 to 1966, he entered the University of California at Berkeley to become a science teacher. When the Army called him back from reser ve status in 1968, he chose to go to prison rather than continue to serve during the Vietnam War. He subsequently earned a Ph.D. in religious studies at Yale University, where he wrote a book about the nineteenth century Darwinian controversies. In 1989 he returned to Berkeley to earn a second Ph.D., this time in molecular and cell biology. He is now a senior fellow at Discovery Institute's Center for the Renewal of Science and Culture (www.discovery.org/ crsc) in Seattle, where he lives with his wife, two children, and mother. He still hopes to become a science teacher. Icons ofEvolution Science or Myth? Why Much oJWhat We TeachAbout Evolution Is Wrong JONATHAN WELLS ILLUSTRATED BY JODY F.

Frank Morton Carpenter (1902-1994): Academic Biography and List of Publications
FRANK MORTON CARPENTER (1902-1994): ACADEMIC BIOGRAPHY AND LIST OF PUBLICATIONS BY DAVID G. FURTH 18 Hamilton Rd., Arlington, MA 02174 The present paper is meant to accompany the preceding one by Elizabeth Brosius, Assistant Editor at the University of Kansas, Paleontological Institute, who was extremely instrumental in aid- ing Prof. Frank Carpenter to finish his Treatise on Invertebrate Paleontology volumes on fossil insects. The Brosius paper is a brief profile taken from her personal interaction with Prof. Carpen- ter as well as numerous interviews about him with his friends, stu- dents, and colleagues. The present paper is intended to be more of an account of Prof. Carpenter's academic background and accom- plishments with the addition of some personal and academic accounts of the author's interaction with Frank Carpenter. Frank Morton Carpenter was born in Boston on 6 September 1902. When he was three years old his family (father Edwin A. and mother Maude Wall) moved from Boston to Revere and at age six his family moved to Melrose where he began to attend Lincoln School the following year. His father worked for the American Express Company but had a strong interest in natural history and taught his elder son (Edwin, four years older than Frank) about the constellations. Edwin later graduated from Harvard, studied astronomy, and became Director of the Astronomical Laboratory at the University of Arizona in Tucson. When Frank Carpenter was a sixth grader at Lincoln School his father encouraged his interest in butterflies and moths. In ninth grade Frank Carpenter began taking out books about insects from the Melrose Public Library. -
