Autor: H. Catherine W. Skinner, Gustave L. Davis, Andrew H. Haims, William H. Straight, Bruce L. McClennan, Darren H. Tanke

Publikováno v: Journal of Vertebrate Paleontology. 29:315-325

High-resolution computed tomography (CT) scans through two fossilized lesions in hadrosaur bone guided paleohistological and stable-isotopic sampling to examine the stages and structures of bone re...

Reflections of surface water, seasonality and climate in stable oxygen isotopes from tyrannosaurid tooth enamel

Autor: Reese E. Barrick, David A. Eberth, William H. Straight

Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 206:239-256

Patterns of isotopic variation in enamel of eight Albertosaurus teeth from the Campanian/Maastrichtian Horseshoe Canyon Formation, Alberta, were measured by serial sampling along the growth axis. Cycles in the isotopic values appear to correlate to p

Testing the Utility of Vertebrate Remains in Recognizing Patterns in Fluvial Deposits: An Example from the Lower Horseshoe Canyon Formation, Alberta

Autor: David A. Eberth, William H. Straight

Publikováno v: PALAIOS. 17:472-490

Depositional cycles in fluvial successions are described here as chronostratigraphic packages of strata founded on a laterally extensive, scour-based, amalgamated channel-sand body, overlain by mudrocks, isolated channel fills, avulsion and splay com

Stable oxygen isotopes from theropod dinosaur tooth enamel: interlaboratory comparison of results and analytical interference by reference standards

Autor: Julia E. Cox, William H. Straight, Jonathan D. Karr, Reese E. Barrick

Publikováno v: Rapid communications in mass spectrometry : RCM. 18(23)

Although previous work has demonstrated that biological phosphates (‘biophosphates’) record significant changes in d 18 O associated with variations in local climate and seasonality, the repeatability of these analyses between laboratories has no
