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 …

There is a growing consensus in early hominin studies that savannas did not play a
significant role in the emergence of human evolutionary processes. Early hominins have …

The long neck of the giraffe has been held as a classic example of adaptive evolution since
Darwin's time. Here we report on an unusual fossil giraffoid, Discokeryx xiezhi, from the early …

Despite much interest in the ecology and origins of the extensive grassland ecosystems of
the modern world, the biogeographic relationships of savannah palaeobiomes of Africa …

Oligocene to Pleistocene floras of Greece are reviewed based on published and
unpublished material. Oldest plant-bearing sediments of Rupelian–Chattian age are …

The analysis of dental microwear is commonly used by paleontologists and anthropologists
to clarify the diets of extinct species, including herbivorous and carnivorous mammals …

The extant diversity of the avian clade Palaeognathae is composed of the iconic flightless
ratites (ostriches, rheas, kiwi, emus, and cassowaries), and the volant tinamous of Central …

Microwear, the quantification of microscopic scratches and pits on the occlusal surfaces of
tooth enamel, is commonly used as a paleodietary proxy. For ungulates (hoofed mammals) …

Despite the increased use of light microscopy in microwear analysis, studies that recognize
observer error are scarce. Nonetheless, microwear analysis based on light microscopy may …

We have recently shown that rainfall, one of the main climatic determinants of terrestrial net
primary productivity (NPP), can be robustly estimated from mean molar tooth crown height …
