A RESTful API for Access to Phylogenetic Tools via the CIPRES Science Gateway
TLDR
The CIP RES RESTful application programmer interface (CRA), a web service that provides programmatic access to all resources and services currently offered by the CIPRES Science Gateway, is described.

The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
TLDR
A phylogenetic tree shows that crown clade Placentalia and placental orders originated after the K-Pg boundary, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats).

Relationships of Cetacea (Artiodactyla) Among Mammals: Increased Taxon Sampling Alters Interpretations of Key Fossils and Character Evolution
TLDR
The phylogenetic position of †Indohyus suggests that the cetacean stem lineage included herbivorous and carnivorous aquatic species, and the taxonomy of living and extinct artiodactylans is revised and proposes explicit node and stem-based definitions for the ingroup.

A DYROSAURID CROCODYLIFORM BRAINCASE FROM MALI
TLDR
A well-preserved crocodyliform specimen from the Maastrichtian or Paleocene of Mali preserves the braincase and posterior dermatocranium that is referred to Dyrosauridae and tentatively referred to Rhabdognathus on the basis of supratemporal fenestra shape.

Impact of increased character sampling on the phylogeny of Cetartiodactyla (Mammalia): combined analysis including fossils
The phylogenetic position of Cetacea (whales, dolphins and porpoises) is an important exemplar problem for combined data parsimony analyses because the clade is ancient and includes many well‐known…

MorphoBank: phylophenomics in the “cloud”
TLDR
MorphoBank is described, a web application and database leveraging software as a service methodology compatible with “cloud” computing technology for the construction of matrices of phenomic data that has enabled an order of magnitude increase in phylophenomic data collection.

An Anatomical and Phylogenetic Study of the Osteology of the Petrosal of Extant and Extinct Artiodactylans (Mammalia) and Relatives
TLDR
It is shown that in many ways the osteology of the hippopotamid ear resembles that of certain stem cetaceamorphans more than it resembles the ear regions of suines (pigs and peccaries), and shortest trees indicate that these similarities are convergent.

The position of Cetacea within mammalia: phylogenetic analysis of morphological data from extinct and extant taxa.
Knowledge of the phylogenetic position of the order Cetacea (whales, dolphins, and porpoises) within Mammalia is of central importance to evolutionary biologists studying the transformations of…

The inner ear of Diacodexis, the oldest artiodactyl mammal
TLDR
The shape of the cochlea suggests that Diacodexis was a high‐frequency hearing specialist, with a high low‐ frequencies hearing limit, and the results are congruent with the postcranial functional analysis for this extinct taxon.

Dyrosaurid (Crocodyliformes: Mesoeucrocodylia) Fossils from the Upper Cretaceous and Paleogene of Mali: Implications for Phylogeny and Survivorship across the K/T Boundary
TLDR
The occurrence of both basal (e.g., Chenanisuchus lateroculi) and highly nested members of Dyrosauridae on both sides of the K/T boundary indicates that dyrosaurid diversification was well underway by the latest Cretaceous, and that most, if not all dyrosauri species survived the extinction event.
