Divergence times estimated from molecular data often considerably predate the earliest known fossil representatives of the groups studied. For the order Primates, molecular data calibrated with various external fossil dates uniformly suggest a mid-Cretaceous divergence from other placental mammals, some 90 million years (Myr) ago, whereas the oldest known fossil primates are from the basal Eocene epoch (54–55 Myr ago). The common ancestor of primates should be earlier than the oldest known… 
Deep time and the search for anthropoid origins.
Overall, molecular phylogenies for mammals agree with some statistical analyses of the primate fossil record in indicating an early origin for primates around 85 Ma ago, and the divergence of haplorhines and strepsirrhines at ca.
Primate Origins: Implications of a Cretaceous Ancestry
A statistical analysis of the primate record allowing for major gaps now indicates a Cretaceous origin of euprimates 80–90 Ma ago, and the known early Tertiary primates are re-interpreted as northern continental offshoots of a ‘second wave’ of primate evolution.
Primate Divergences through an Integrated Analysis of Palaeontological and Molecular Data
—Estimation of divergence times is usually done using either the fossil record or sequence data from modern species. We provide an integrated analysis of palaeontological and molecular data to give
Temporal ranges and ancestry in the hominin fossil record: The case of Australopithecus sediba
In attempting to resolve the phylogenetic relationships of fossil taxa, researchers can use evidence from two sources – morphology and known temporal ranges. For most taxa, the available evidence is

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.
Constraints on clade ages from fossil outgroups
If all Mesozoic eutherians are regarded as outgroups of Placentalia, then the last common ancestor of modern placental mammals and their Cenozoic allies lived between 65 and 88–98 million years ago, depending on the assumed cladogram and the number of outgroups included in the analysis.
Macroevolutionary Dynamics and Historical Biogeography of Primate Diversification Inferred from a Species Supermatrix
A robust molecular phylogeny for 70 primate genera and 367 primate species is generated based on a concatenation of 69 nuclear gene segments and ten mitochondrial gene sequences, most of which were extracted from GenBank to find support for the hypothesis that the most recent common ancestor of living Primates resided in Asia.

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.
Bayesian Phylogenetic Estimation of Clade Ages Supports Trans-Atlantic Dispersal of Cichlid Fishes.
This work develops a flexible new approach to Bayesian age estimation that combines advantages of node dating and the FBD model, and defines calibration densities on the basis of first fossil occurrences and sampling rate estimates that can be specified separately for all clades.


Molecular dating and biogeography of the early placental mammal radiation.
An integrated genomic, paleontological, and biogeographic hypothesis is proposed to account for these earliest splits on the placental mammal family tree and address current discrepancies between fossil and molecular evidence.
Continental breakup and the ordinal diversification of birds and mammals
THE classical hypothesis for the diversification of birds and mammals proposes that most of the orders diverged rapidly in adaptive radiations after the Cretaceous/Tertiary (K/T) extinction event 65
Absolute measures of the completeness of the fossil record
Quantitative, widely applicable absolute measures of completeness at two taxonomic levels for a broader sample of higher taxa of marine animals than has previously been available are presented and it is found that completeness is rather high for many animal groups.
Evolutionary and preservational constraints on origins of biologic groups: divergence times of eutherian mammals.
Some molecular clock estimates of divergence times of taxonomic groups undergoing evolutionary radiation are much older than the groups' first observed fossil record. Mathematical models of branching
Endemic African mammals shake the phylogenetic tree
DNA sequences from three mitochondrial genes and two nuclear genes are analysed to examine relationships of insectivores to other mammals and suggest that there was an extensive African radiation from a single common ancestor that gave rise to ecologically divergent adaptive types.
Molecular phylogenetics and the origins of placental mammals
The potential weaknesses of limited character and taxon sampling are addressed in a comprehensive molecular phylogenetic analysis of 64 species sampled across all extant orders of placental mammals, providing new insight into the pattern of the early placental mammal radiation.
Stochastic Models of Phylogeny and the Evolution of Diversity
This work has extended the use of equilibrium models to examine patterns of phyletic diversification in the fossil record and generated evolutionary trees by stochastic simulation and classified their lineages into clades.
Primate origins: plugging the gaps
Although the origin of the simian primates is obscure, new fossil evidence could push it further back by at least 10 million years, reflecting the low sampling level of the primate fossil record, which can potentially also lead to underestimation of times of origin within thePrimate tree.
The marsupial mitochondrial genome and the evolution of placental mammals.
The entire nucleotide sequence of the mitochondrial genome of the American opossum, Didelphis virginiana, was determined and it can be shown that rodents represent an earlier branch among placental mammals than primates and artiodactyls and that artiodACTyls share a common ancestor with carnivores.
The adequacy of the fossil record
The fossil record of cheilostome bryozoa in the Neogene and Quaternay of tropical America - adequacy for phylogenetic and evolutionary studies and the quality of the fossil record are studied.
