The fossil record provides the primary source of data for calibrating the origin of clades. Although minimum ages of clades are given by the oldest preserved fossil, these underestimate the true age, which must be bracketed by probabilistic methods based on multiple fossil occurrences. Although most of these methods assume uniform preservation rates, this assumption is unsupported over geological timescales. On geologically long timescales (more than 10 Myr), the origin and cessation of… Expand

TLDR
The utility of time information from fossils in phylogeny estimation and the search for ancestors in the fossil record is discussed, including node-calibrations where lineage divergence times are constrained using probability densities and tip-cal calibrations where fossil species at the tips of the tree are assigned dates from dated rock strata.

Using the Fossil Record to Evaluate Timetree Timescales
TLDR
Five primary methods have been developed to estimate maximum age brackets and their relative magnitudes are reviewed, which typically correlate with the age of the group, its geographic range, and species richness. Expand
Detecting diversification rates in relation to preservation and tectonic history from simulated fossil records
Abstract. For mammals today, mountains are diverse ecosystems globally, yet the strong relationship between species richness and topographic complexity is not a persistent feature of the fossilExpand
Assessing the impact of incomplete species sampling on estimates of speciation and extinction rates
TLDR
An FBD model is presented that estimates of tree-wide diversification rates from stratigraphic range data when the underlying phylogeny of the fossil taxa may be unknown, and is robust and more accurate than the alternative methods, particularly when fossil data are sparse. Expand
What do we know about the fossil record of pinnipeds? A historiographical investigation
TLDR
While the pinniped fossil record may have adequate temporal and taxonomic coverage, it has a strong geographical bias and its comparability is hindered by the incompleteness of type specimens, which should be taken into account when addressing patterns of their past diversity, evolutionary history and paleoecology. Expand
Estimating the age of poorly dated fossil specimens and deposits using a total-evidence approach and the fossilized birth-death process
TLDR
This study explores whether reliable age estimates for fossil specimens can be obtained from Bayesian total-evidence phylogenetic analyses under the fossilized birth-death model and shows that estimates of fossil ages obtained through such an analysis are accurate. Expand
Fossils improve phylogenetic analyses of morphological characters
TLDR
Simulation results show that fossil taxa improve phylogenetic analysis of morphological datasets, even when highly fragmentary, and tip-dated analyses under the fossilized birth–death process outperform undated methods of inference, demonstrating that the stratigraphic ages of fossils contain vital phylogenetic information. Expand
Ecological regime shift preserved in the Anthropocene stratigraphic record
TLDR
It is shown that the youngest (Anthropocene) fossil record on the northern Adriatic continental shelf provides decadal-scale resolution that accurately documents an abrupt ecological change affecting benthic communities during the twentieth century. Expand
The Effect of Fossil Sampling on the Estimation of Divergence Times With The Fossilised Birth Death Process.
TLDR
This work assesses the performance of the FBD-Skyline model when implementing multiple approaches to incorporating subsampled fossil occurrences and demonstrates that it is necessary to account for all available fossil occurrence data to achieve the most accurate estimates of clade age. Expand
The Anthropocene fossil record of terrestrial mammals
Abstract This paper reviews how human impacts produced a marked shift from natural processes in the potential input of terrestrial mammals to the fossil record, both in composition of the mammal taxaExpand
