Paleosols (fossil soils) are preserved throughout the geologic record in depositional settings
ranging from alluvial systems to between basalt flows. Until recently, paleosols were studied …

Although silicon occurs in all plants, it is an element that is largely overlooked by many plant
ecologists and most plant-related research on silicon comes from agronomy, archaeology …

This new edition of the definitive work on doing paleoethnobotany brings the book up to date
by incorporating new methods and examples of research, while preserving the overall …

Many plants take up soluble monosilicic acid from the soil. Some of these plants
subsequently deposit it as cell inclusions of characteristic structure. This article describes the …

This paper outlines a general approach for analyzing siliceous microfossils from plants
(phytoliths) in geologic sediments and uses this method to reconstruct the evolution of …

This paper presents a brief synopsis of work on relationships between mammalian tooth
form and function, and considers the role of dental wear in studies of mammal teeth …

Because of a dearth of Cenozoic grass fossils, the timing of the taxonomic diversification of
modern subclades within the grass family (Poaceae) and the rise to ecological dominance of …

By the end of the Eocene (37 Ma), species of the genus Hesperocyon began to appear. A
single species, H. gregarius, has been found in the badlands of the western Great Plains …

Mechanisms for concentrating carbon around the Rubisco enzyme, which drives the carbon-
reducing steps in photosynthesis, are widespread in plants; in vascular plants they are …

Phytoliths, microscopic plant silica bodies, are often preserved in modern and fossil soils
and sediment, as well as in archaeological contexts. They record unique characteristics of …
