The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals
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).
Higher Level Classification of Phyllostomid Bats with a Summary of DNA Synapomorphies
It is proposed that a classification based on the strengths of the most complete morphological and genetic data sets will provide the most robust classification for multiple uses by science and society.
Morphological Diagnoses of Higher-Level Phyllostomid Taxa (Chiroptera: Phyllostomidae)
The goal of this paper is to provide morphological diagnoses of higher-level taxa (subtribes, tribes, and subfamilies) of phyllostomid relationships, areas of the greatest controversy.

The biological processes that generate phylogenetic conflict are ubiquitous, and overcoming incongruence requires better models and more data than have been collected even in well‐studied organisms such as phyllostomid bats.

The Age of Discovery for bats is ongoing, and new taxonomic and systematic discoveries, especially those involving cryptic species and unrecognized diversity, are rapidly increasing with the advent of modern genetics.

This analysis supports two main clades of molossids, both of which mingle Old World and New World taxa and recommends that the subgenera of Molossops sensu lato and Austronomus be recognized at the generic level.
Next-generation phenomics for the Tree of Life
The goal is to assemble large phenomic datasets built using new methods and to provide the public and scientific community with tools for phenomic data assembly that will enable rapid and automated study of phenotypes across the Tree of Life.
Response to Comment on “The Placental Mammal Ancestor and the Post–K-Pg Radiation of Placentals”
Contrary to Springer et al., post–K-Pg placental diversification does not require “virus-like” substitution rates and even constraining clade ages to their model, the explosive model best explains placental evolution.
Crowds Replicate Performance of Scientific Experts Scoring Phylogenetic Matrices of Phenotypes
A procedure that predicts the difficulty of each character and that can be used to assign harder characters to experts and easier characters to a nonexpert crowd for scoring is introduced and it is shown that crowds can produce matrices with over 90% of cells scored correctly while reducing the number of cells to be scored by experts by 50%.

This work has developed an approach to detect and localize object parts in standardized images of bat skulls by learning a tree parts model on the transferred annotations, and applying this model to detects and label teeth in the unlabeled images.
