A caenagnathid tibia (Theropoda: Oviraptorosauria) from the upper Campanian Kirtland Formation of New Mexico

Caenagnathid oviraptorosaurian dinosaurs, long considered enigmas, have now become relatively easy to recognize in the fossil record of Asia and North America. This has revealed their presence in several formations spanning the Late Cretaceous, providing new insights including showing that they were more widespread in the southern parts of North America than previously recognized. Here we add to this record by describing a nearly complete right tibia from the upper Campanian De-na-zin Member of the Kirtland Formation of New Mexico, which represents the first caenagnathid material from these beds. The bone is nearly identical in morphology and size to its counterpart in the Mongolian Elmisaurus rarus, reinforcing a suite of previously-identified features that allow for straightforward recognition of caenagnathid tibiae. The growing body of caenagnathid material continues to blur boundaries between features once considered distinct, raising doubts that some taxa established from sparse material, including Ojoraptorsaurus boerei, are actually valid

Countering terror: new directions post '911'

The essays in this book were originally presented as speeches to the SDSC conference "Post 11 September - New Directions, held on 11 September 2002. They assess where counter-terrorism efforts are, and should be, headed as a consequence of the attacks on the US homeland and the initiation of the "war on terror. Several interesting themes emerge, including the prospects for the American-led campaign against global terrorism, security threats in Southeast Asia, and the strategic implications for Australia. Contributors include the Secretary of the Commonwealth Attorney General's Department, Robert Cornall; Executive Director of the Australian Bureau of Criminal Intelligence, Dr Grant Wardlaw; four members of the SDSC, Professor Paul Dibb AM, Professor Desmond Ball, Dr Coral Bell and Dr Ron Huisken; as well as two leading authorities on Southeast Asia, Dr Greg Fealy and Dr John Funston. The book is edited by Clive Williams MG, and Dr Brendan Taylor

Effects of Dam Nutrition on Growth and Reproductive Performance of Heifer Calves

A 3-year experiment evaluated the effects of maternal nutrition on growth and reproductive performance of heifer calves. Supplementing cows with protein during late gestation resulted in heifers that were heavier at weaning and breeding, had higher pregnancy rates, and calved earlier. Allowing cows to graze meadows after calving improved calf weaning weight but not heifer reproductive performance. Heifers from cows that were fed hay after calving had reduced DMI and improved residual feed intake if their dams were supplemented with protein during gestation, but ADG and G:F were not affected by dam supplementation or spring feeding strategies
