It has long been accepted that the adaptive radiation of modern placental mammals, like that of modern birds, did not begin until after the Cretaceous/Tertiary (K/T) boundary 65 million years (Ma) ago, following the extinction of the dinosaurs. The first undoubted fossil relatives of modern primates appear in the record 55 Ma ago. However, in agreement with evidence from molecular phylogenies calibrated with dates from denser parts of the fossil record, a statistical analysis of the primate… Expand
Origins and Evolution of Early Primates
TLDR
Considering the molecular biological analyses and the recent discoveries of fossil evidence, the late Cretaceous circum-Tethys region could have been the stage for the initial evolution of primates. Expand
Primate phylogenetic relationships and divergence dates inferred from complete mitochondrial genomes.
TLDR
The divergence date estimates of the Strepsirrhine/Haplorhine split support an origin of crown primates in the Late Cretaceous, at around 74Ma, which supports a short-fuse model of primate origins, whereby relatively little time passed between the origin of the order and the diversification of its major clades.

Timing primate evolution: Lessons from the discordance between molecular and paleontological estimates
TLDR
It is argued that discordance is a predictable phenomenon that provides valuable information about the tempo and mode of primate molecular and morphological evolution and how a better understanding of these factors can help to improve the understanding ofPrimate evolution. Expand
Dating primate divergences through an integrated analysis of palaeontological and molecular data.
TLDR
An integrated analysis of palaeontological and molecular data to give estimates of primate divergence times that utilize both sources of information and find that these age estimates are older than previously reported dates for all but one of these nodes. Expand
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 giveExpand
Contextualising primate origins – an ecomorphological framework
TLDR
Current perspectives on the origin and early evolution of primates are reviewed, paying particular attention to their phylogenetic and environmental contextualisation, before attempting an up‐to‐date ecomorphological synthesis of primate origins. Expand
Estimating primate divergence times by using conditioned birth-and-death processes.
TLDR
The pattern of diversification through the Cenozoic can be combined with a model for speciation to give a distribution for the age of the primates and it is concluded that it is not possible, with this model, to rule out a Cretaceous origin for the primates. Expand
Estimating the primate divergence time using conditioned birth-and-death processes
The fossil record provides a lower bound on the primate divergence time of 54.8 million years ago, but does not provide an explicit estimate for the divergence time itself. We show how the pattern ofExpand
Macroevolutionary effects on primate trophic evolution and their implications for reconstructing primate origins.
TLDR
The present study tests two alternative hypotheses that are compatible with an insectivorous ancestor: that trophic evolution was biased, such that herbivory evolved repeatedly with few shifts back to insectivory, and that insectivoured lineages have diversified at a lower rate than herbivorous lineages owing to differential trophics effects on speciation and extinction probabilities. Expand
Using Phylogenomic Data to Explore the Effects of Relaxed Clocks and Calibration Strategies on Divergence Time Estimation: Primates as a Test Case
TLDR
It is shown that for eight core nodes in the phylogeny, uncertainty in time estimates is close to the theoretical limit imposed by fossil uncertainties, and these estimates are unlikely to be improved by collecting additional molecular sequence data. Expand

Deep time and the search for anthropoid origins.
TLDR
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. Expand
New Light on the Dates of Primate Origins and Divergence
TLDR
The known fossil record for undoubted primates of modern aspect dates back to the beginning of the Eocene epoch, about 55 million years ago, and it is widely accepted among primate paleontologists that primates originated during the preceding Paleocene epoch. Expand

TLDR
Paleofaunal data confirm that there were fewer mammalian species during the latest Cretaceous than during any interval of the Cenozoic, and that a massive diversification took place during the early Paleocene, immediately after a mass extinction. Expand
Ancient single origin for Malagasy primates.
TLDR
It is concluded that primate origins were marked by rapid speciation and diversification sometime before the late Paleocene, and called for a revision of primate classifications in which the dwarf and mouse lemurs are placed within the Afro-Asian lorisiforms. Expand

TLDR
If the molecular results are correct, then the first half of the fossil record of modern birds and mammals is missing, and the most likely explanation is that they simply did not exist, and that the molecular clock runs fast during major radiations. Expand
Definitive fossil evidence for the extant avian radiation in the Cretaceous
TLDR
A rare, partial skeleton from the Maastrichtian of Antarctica is identified as the first Cretaceous fossil definitively placed within the extant bird radiation, and phylogenetic analyses supported by independent histological data indicate that a new species, Vegavis iaai, is a part of Anseriformes (waterfowl) and is most closely related to Anatidae, which includes true ducks.

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 65Expand
Quantitative Analysis of the Timing of the Origin and Diversification of Extant Placental Orders
TLDR
Although the fossil record is incomplete, it appears adequate to reject the hypothesis that orders of placentals began to diversify before the K/T boundary; thus, early Tertiary ordinal diversification is real. Expand
An Early Miocene anthropoid skull from the Chilean Andes
TLDR
The discovery of a complete platyrrhine skull from the Andes of central Chile is reported, by far the best preserved Tertiary primate cranium from South America, indicating an Early Miocene age and a likely African origin for New World monkeys. Expand
Using the fossil record to estimate the age of the last common ancestor of extant primates
TLDR
A new statistical method is presented, based on an estimate of species preservation derived from a model of the diversification pattern, that suggests a Cretaceous last common ancestor of primates, approximately 81.5 Myr ago, close to the initial divergence time inferred from molecular data. Expand
