The Origins of C4 Grasslands: Integrating Evolutionary and Ecosystem Science
Grassland Emergence The evolution of the C4 photosynthetic pathway from the ancestral C3 pathway in grasses led to the establishment of grasslands in warm climates during the Late Miocene (8 to 3Expand

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 open-habitatExpand
Dinosaur Coprolites and the Early Evolution of Grasses and Grazers
Silicified plant tissues (phytoliths) preserved in Late Cretaceous coprolites from India show that at least five taxa from extant grass (Poaceae) subclades were present on the Indian subcontinentExpand
A New Chronology for Middle Eocene-Early Miocene South American Land Mammal Ages
Cenozoic South American Land Mam- mal Ages (SALMAs) have historically been correlated to the geologic time scale using 40 Ar/ 39 Ar dating and magnetostratigraphy. At Gran Barranca (68.7°W,Expand
Using phytolith assemblages to reconstruct the origin and spread of grass-dominated habitats in the great plains of North America during the late Eocene to early Miocene
Abstract 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 grasslands inExpand
Late Cretaceous origin of the rice tribe provides evidence for early diversification in Poaceae.
Rice and its relatives are a focal point in agricultural and evolutionary science, but a paucity of fossils has obscured their deep-time history. Previously described cuticles with silica bodiesExpand
The spread of grass-dominated habitats in Turkey and surrounding areas during the Cenozoic: Phytolith evidence
Abstract The arrival of hipparionine horses in the eastern Mediterranean region around 11 Ma was traditionally thought to mark the simultaneous westward expansion of savanna vegetation acrossExpand
Evolution of Grasses and Grassland Ecosystems
The evolution and subsequent ecological expansion of grasses (Poaceae) since the Late Cretaceous have resulted in the establishment of one of Earth's dominant biomes, the temperate and tropicalExpand
The origin and spread of grass-dominated ecosystems in the late Tertiary of North America: preliminary results concerning the evolution of hypsodonty
Abstract Sediment samples were collected in northwestern Nebraska from the following lithologic units: (1) the upper Oligocene Monroe Creek Formation, the lower Miocene Harrison Formation and ‘upperExpand
Molecular dating, evolutionary rates, and the age of the grasses.
Many questions in evolutionary biology require an estimate of divergence times but, for groups with a sparse fossil record, such estimates rely heavily on molecular dating methods. The accuracy ofExpand
