Morphological Evidence for the Phylogeny of Cetacea
Many of the clades within Odontoceti in the most parsimonious trees of this study are at odds with recent phylogenetic analyses, indicating that additional analyses, which include molecular and anatomical data as well as extant and extinct taxa, are needed.
Phylogenetic relationships of Icaronycteris, Archaeonycteris, Hassianycteris, and Palaeochiropteryx to extant bat lineages, with comments on the evolution of echolocation and foraging strategies in…
A supermatrix analysis of genomic, morphological, and paleontological data from crown Cetacea
The parsimony analysis of the supermatrix and the analysis of morphology constrained to fit the ML/Bayesian molecular tree yielded broadly congruent phylogenetic hypotheses, implying that many character states shared by river dolphins evolved in their oceanic ancestors, contradicting the hypothesis that these characters are convergent adaptations to fluvial habitats.
A phylogenetic blueprint for a modern whale.
The petrosal and inner ear of Herpetocetus sp. (Mammalia: Cetacea) and their implications for the phylogeny and hearing of archaic mysticetes
This paper describes the petrosal (periotic) and the inner ear of Herpetocetus sp., an archaic mysticete whale (Mysticeti, Mammalia) from the Yorktown Formation (Pliocene) of North Carolina, USA.…
Relationships of Endemic African Mammals and Their Fossil Relatives Based on Morphological and Molecular Evidence
Analyses of anatomical and DNA sequence data run on a parallel supercomputer that include fossil taxa support the inclusion of tenrecs and golden moles in the Afrotheria, an endemic African clade of placental mammals, and support the position of AfroTheria as well-nested, not basal, within Placentalia.
A New Protocetid Whale (Cetacea: Archaeoceti) from the Late Middle Eocene of South Carolina
A new genus and species of protocetid cetacean is described from a partial skull, the posterior portion of both dentaries, 13 vertebrae, and elements of 15 ribs found in the Cross Member of the late middle Eocene Tupelo Bay Formation in Berkeley County, South Carolina.
New Morphological Evidence for the Phylogeny of Artiodactyla, Cetacea, and Mesonychidae

Abstract Parsimony-based analyses of a data set including 68 taxa coded for 186 morphological characters corroborate monophyly of Artiodactyla (even-toed ungulates), Suiformes (hippos, pigs,…
Eocene–Oligocene transition in Central Asia and its effects on mammalian evolution
The Eocene-Oligocene boundary (EOB) marks a period of dramatic global climatic change correlated with pronounced mammalian faunal change. The timing of these events is well constrained in North…
Phylogenetic Relationships of Extinct Cetartiodactyls: Results of Simultaneous Analyses of Molecular, Morphological, and Stratigraphic Data
Both analyses supported the exclusion of Mesonychia from Cetartiodactyla and a close phylogenetic relationship between Hippopotamidae and Cetacea, and added stratigraphic information to the intrinsic dataset, which found fewer most parsimonious trees.
