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.

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.

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

- 1 July 2005
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
- B. Kraatz, J. Geisler

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
- J. Geisler, M. Uhen
- Biology, Environmental ScienceJournal of mammalian evolution
- 1 June 2005
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.
