Correlation between isotope records in marine and continental carbon reservoirs near the Palaeocene/Eocene boundary
CHANGES in the isotope content of the large marine carbon reservoir can force shifts in that of the smaller carbon pools in the atmosphere and on land. The carbon isotope compositions of marineExpand
Rapid Asia-Europe-North America geographic dispersal of earliest Eocene primate Teilhardina during the Paleocene-Eocene Thermal Maximum.
Analysis of morphological characteristics of all four species supports an Asian origin and a westward Asia- to-Europe-to-North America dispersal for Teilhardina and high-resolution isotope stratigraphy indicates that this dispersal happened in an interval of approximately 25,000 yr. Expand
Cranial Anatomy and Evolution of Early Tertiary Plesiadapidae (Mammalia, Primates)
The Bighorn Basin of Wyoming is important paleontologically for two reasons: it is the only place in the world where the early Cenozoic diversification of mammalian life is recorded through such a long sequence of continental sediments representing virtually continuous deposition, and many areas of the Bighorns are richly fossiliferous, making it possible to trace evolutionary changes through time in much more detail than is possible elsewhere.

Complete Primate Skeleton from the Middle Eocene of Messel in Germany: Morphology and Paleobiology
The absence of a toilet claw and a toothcomb demonstrates that Darwinius masillae is not simply a fossil lemur, but part of a larger group of primates, Adapoidea, representative of the early haplorhine diversification. Expand
Allometric scaling in the dentition of primates and prediction of body weight from tooth size in fossils.
Regressions based on tooth size in generalized primates yield reasonable estimates of body weight, but much remains to be learned about tooth size and body size scaling in more restricted systematic groups and dietary guilds. Expand
Origin of Whales from Early Artiodactyls: Hands and Feet of Eocene Protocetidae from Pakistan
Partial skeletons of two new fossil whales, Artiocetus clavis and Rodhocetus balochistanensis, are among the oldest known protocetid archaeocetes, and are important in augmenting the diversity of early Protocetidae and clarifying that Cetacea evolved from early Artiodactyla rather than Mesonychia. Expand
Rates of Evolution: Effects of Time and Temporal Scaling
Rates of morphological evolution documented in laboratory selection experiments, historical colonization events, and the fossil record are inversely related to the interval of time over which they are measured, and these rates must be scaled against interval length before they can be compared.
