A fossil leaf fragment collected from the Ogallala Formation of northwestern Kansas exhibits features found in taxa of the modern grass subfamily Chloridoideae. These include bullet-shaped, bicellular microhairs, dumbbell-shaped silica bodies, cross-shaped suberin cells, papillae, stomata with low dome- to triangular-shaped subsidiary cells, and Kranz leaf anatomy. The leaf fragment extends the fossil record of plants that show both anatomical and external micromorphological features indicating… Expand
Tomlisonia thomassonii, gen. et sp. nov., a permineralized grass from the upper miocene Ricardo Formation, California
TLDR
The occurrence of this fossil grass in the Ricardo Formation suggests, at least by the Miocene, the establishment of a Mediterranean chaparral type grassland in the Mojave desert region and climatic condition conducive to the growth and expansion of several grass species. Expand
Examination of structure and molecular phylogenetic relationships of some graminicolous symbionts in genera Epichloe and Parepichloe
TLDR
Phylogenetic studies employing the ITS1 region of the rDNA suggest that Epichloe, as defined to include both endophytic and epibiotic species, is polyphyletic. Expand
Tomlinsonia stichkania Sp. Nov., a Permineralized Grass from the Pliocene to (?)Pleistocene China Ranch Beds in Sperry Wash, California
TLDR
Based upon its leaf anatomy and its low δ13C/12C ratios, this species is proposed as a C3 grass, which is only the second or third grass species described from specimens with this type of preservation. Expand
The Miocene macroflora of the northern Ogallala Group, northern Nebraska and southern South Dakota
The results of the first comprehensive paleobotanical survey of the northern portion of the late Miocene Ogallala Group are discussed. Several species of fossilized fruiting structures from vascularExpand
A BARAMINOLOGICAL ANALYSIS OF SUBTRIBE FLAVERIINAE ( ASTERACEAE : HELENIEAE ) AND THE ORIGIN OF BIOLOGICAL COMPLEXITY
WHAT THIS ARTICLE IS ABOUT The subtribe Flaveriinae (Asteraceae: Helenieae) includes a number of plant species sometimes called yellowtops, glowworts, and false broomweed. Different species of thisExpand
Photosynthetic pathway of grass fossils from the upper Miocene Dove Spring Formation, Mojave Desert, California.
Abstract The spread of grasslands in the Miocene and of C4 grasses in the late Miocene-Pliocene represents a major development in terrestrial plant evolution that affected the climate system andExpand

Fossil horses, carbon isotopes and global change.
TLDR
Isotopic analysis of fossil horse teeth indicates a predominantly C(3) diet consisting of mixed browse/grass or predominantly C (3) grasses until the latest Miocene, which seems related to declining equid diversity. Expand
The Neogene transition from C3 to C4 grasslands in North America: assemblage analysis of fossil phytoliths
Abstract The rapid ecological expansion of grasses with C4 photosynthesis at the end of the Neogene (8-2 Ma) is well documented in the fossil record of stable carbon isotopes. As one of the mostExpand
The expansion of C4 grasses and global change in the late Miocene: Stable isotope evidence from the Americas
j3C values in paleosols and fossil teeth have been used to document the expansion of C, plants in South Asia, Africa, and North America during the late Miocene. However, the exact timing and rate ofExpand

A C4 plant from the Pliocene
TLDR
Fossil evidence is reported indicating that C4 plants occurred at least during the late Tertiary period, suggesting that ancestral non-Kranz C3 grasses originated during the Cretaceous period. Expand
Grass Evolution, the Kranz Syndrome, 13C/12C Ratios, and Continental Drift
TLDR
Now that geology has accepted Wegenerian drifting continents and the break-up of an ancient single world-continent (Pangaea) by rifting under the concept of plate tectonics, evolution of the Gramineae can be discussed in terms of that concept. Expand
Occurrence of C3 and C4 photosynthetic pathways in North American Grasses.
