Dietary Change and Evolution of Horses in North America

A survey of horse-teeth wear during the past 55 million years implies that evolutionary pressures were generally low, suggesting intervals of stronger selection for the evolution of dentitions, including the early Miocene shortly before the first appearance of Equinae, the horse subfamily in which high-crowned dentitions evolved.

Species Taxonomy, Phylogeny, and Biogeography of the Brontotheriidae (Mammalia: Perissodactyla)

A radical revision in the higher classification of brontotheres is presented and one new species, Wickia brevirhinus, is named and six other potential species are recognized but remain unnamed due to very poor fossil material.

EFFECT OF ONTOGENETIC-AGE DISTRIBUTION IN FOSSIL AND MODERN SAMPLES ON THE INTERPRETATION OF UNGULATE PALEODIETS USING THE MESOWEAR METHOD

This work presents a new probabilistic framework for estimating the age of the Carboniferous strata of the Tournaisian to Westphalian age, which has implications for understanding the distribution of infectious disease and infectious disease in the fossilised period.

Error rates and observer bias in dental microwear analysis using light microscopy

Rather than using pre-published microwear databases of extant species as a basis for interpreting paleodiet, researchers may be better served by building shared microwear image libraries, with which observers could generate their own data for the basis of making paleod Dietary inferences.

The Brachial Plexus of the Sumatran Rhino (Dicerorhinus sumatrensis) and Application of Brachial Plexus Anatomy Toward Mammal Phylogeny

Despite a high rate of polymorphism, the peripheral nervous system seems to carry a phylogenetic signal consistent with other morphological data, and it is suggested the brachial plexus will contribute valuable data for phylogenetic testing.

Coevolution of Tooth Crown Height and Diet in Oreodonts (Merycoidodontidae, Artiodactyla) Examined with Phylogenetically Independent Contrasts

Results do not clearly indicate that the overall trend of increasing dietary abrasion imposed sufficient selection to drive crown height evolution in oreodonts, and direct fossil evidence of dietary ab rasion as a causal factor in the evolution of crown height, at least in this clade is elusive.

Sexual Dimorphism and Mortality Bias in a Small Miocene North American Rhino, Menoceras arikarense: Insights into the Coevolution of Sexual Dimorphism and Sociality in Rhinos

Demographic patterns in the Menoceras assemblage indicate that males suffered from a localized risk of elevated mortality at an age equivalent to the years of early adulthood, and indicates that young males were susceptible to the aggressive behaviors of dominant individuals in areas conducive to fossilization.

Comparative dental microwear of ruminant and perissodactyl molars: Implications for paleodietary analysis of rare and extinct ungulate clades

Although it is not clear what heritable variables may phylogenetically bias dentalmicrowear, extant ruminants may not be appropriate models for themicrowear of other large herbivores.
