To discover interordinal relationships of living and fossil placental mammals and the time of
origin of placentals relative to the Cretaceous-Paleogene (K-Pg) boundary, we scored 4541 …

The precise pattern and timing of speciation events that gave rise to all living placental
mammals remain controversial. We provide a comprehensive phylogenetic analysis of …

The timing of the diversification of placental mammals relative to the Cretaceous–Paleogene
(KPg) boundary mass extinction remains highly controversial. In particular, there have been …

Molecular phylogenetic studies have resolved placental mammals into four major groups,
but have not established the full hierarchy of interordinal relationships, including the position …

Competing hypotheses for the timing of the placental mammal radiation focus on whether
extant placental orders originated and diversified before or after the Cretaceous-Tertiary …

O'Leary et al.(O'Leary et al. 2013 Science 339, 662–667.(doi: 10.1126/science. 1229237))
performed a fossil-only dating analysis of mammals, concluding that the ancestor of …

Previous molecular analyses of mammalian evolutionary relationships involving a wide
range of placental mammalian taxa have been restricted in size from one to two dozen gene …

Estimates of the time of origin for placental mammals from DNA studies span nearly the
duration of the Cretaceous period (145 to 65 million years ago), with a maximum of 129 …

From shrews to blue whales, placental mammals are among the most diverse and
successful vertebrates on the Earth. Arising sometime near the Late Cretaceous, this broad …

The precise hierarchy of ancient divergence events that led to the present assemblage of
modern placental mammals has been an area of controversy among morphologists …
