Stable carbon isotope analysis in tooth enamel is a well-established approach to infer C3 and C4 dietary composition in fossil mammals. The bulk of past work has been conducted on large herbivorous mammals. One important finding is that their dietary

Autor: Octávio Mateus, Kurt M. Ferguson, A. Olimpio Goncalves, Louis L. Jacobs, Michael J. Polcyn, C Strganac, T. da Silva Tavares, Maria Luísa Morais

Publikováno v: Netherlands Journal of Geosciences - Geologie en Mijnbouw. 94:137-143

Stable oxygen isotope values of inoceramid marine bivalve shells recovered from Bentiaba, Angola, are utilised as a proxy for paleotemperatures during the Late Cretaceous development of the African margin of the South Atlantic Ocean. The δ18O values

Stable Isotopes from Marine Shells, Ancient Environments, and Human Subsistence on Middle Holocene Santa Rosa Island, California, USA

Autor: Torben C. Rick, John A. Robbins, Kurt M. Ferguson

Autor: L.H. Taylor, Kurt M. Ferguson, Michael J. Polcyn, Louis L. Jacobs

Publikováno v: Netherlands Journal of Geosciences. 84:269-281

The north-central Texas Cretaceous section and its contained fossils, as compared to sections at ‘Ein Yabrud in the eastern Mediterranean region, demonstrate that dolichosaurs and primitive mosasaurs inhabited marine environments at least from the
