Sampling and Faunal Turnover in Early Eocene Mammals

Badgley, C. and Gingerich, P. D., 1988. Sampling and faunal turnover in Early Eocene mammals. Palaeogeogr., Palaeoclimatol., Palaeoecol., 63: 141-157. Faunal turnovers in the fossil record are episodes of synchronous appearance and disappearance of species from a community, often resulting in net change in species richness. We studied the biostratigraphic record of faunal turnover involving ear...

3 Testing Models of Faunal Turnover with Neogene Mammals from Pakistan

mammalian faunas. This model is a modified form of Vrba’s turnover-pulse hypothesis, which posits that changes in the physical environment drive speciation, extinction, and local faunal turnover (Vrba 1995a). Model 2 emphasizes the dominance of species with large population sizes and large geographic ranges through intervals of environmental change. This model arises from the literature about m...

New fossil evidence on the sister-group of mammals and early mesozoic faunal distributions.

Newly discovered remains of highly advanced mammal-like reptiles (Cynodontia: Tritheledontidae) from the Early Jurassic of Nova Scotia, Canada, have revealed that aspects of the characteristic mammalian occlusal pattern are primitive. Mammals and tritheledontids share an homologous pattern of occlusion that is not seen in other cynodonts. The new tritheledontids represent the first definite rec...

Stable Isotopes in Early Eocene Mammals as Indicators of Forest Canopy Structure and Resource Partitioning

—The three dimensional structure of vegetation is an important component of ecosystems, yet it is difficult to reconstruct from the fossil record. Forests or woodlands prevailed at mid-latitudes in North America during the early Eocene but tree spacing and canopy structure are uncertain. Here we use stable carbon isotope values (!13C ) in early Eocene mammalian faunas to infer canopy structure....

Quantification and Sampling of Faunal Remains in Owl Pellets

Paleozoologists and taphonomists have long recognized various properties of quantification and sampling with respect to collections they study. Those same properties attend samples of modern owl pellets. The particular skeletal elements identified and the way in which prey remains are grouped for tallying both influence measures of relative prey abundance in a collection of 56 barn-owl (Tyto al...
