Paleontological evidence to date the tree of life
MJ Benton, PCJ Donoghue - Molecular biology and evolution, 2007 - academic.oup.com
The role of fossils in dating the tree of life has been misunderstood. Fossils can provide
good “minimum” age estimates for branches in the tree, but “maximum” constraints on those …

A divergence dating analysis of turtles using fossil calibrations: an example of best practices
Turtles have served as a model system for molecular divergence dating studies using fossil
calibrations. However, because some parts of the fossil record of turtles are very well known …

A new chronology for middle Eocene–early Miocene South American land mammal ages
Abstract Cenozoic South American Land Mammal Ages (SALMAs) have historically been

Towards a robust and consistent middle Eocene astronomical timescale
Until now, the middle Eocene has remained a poorly constrained interval of efforts to
produce an astrochronological timescale for the entire Cenozoic. This has given rise to a so …

Diachronous episodes of Cenozoic erosion in southwestern North America and their relationship to surface uplift, paleoclimate, paleodrainage, and paleoaltimetry
SM Cather, CE Chapin, SA Kelley - Geosphere, 2012 - pubs.geoscienceworld.org
The history of erosion of southwestern North America and its relationship to surface uplift is a
long-standing topic of debate. We use geologic and thermochronometric data to reconstruct …
