TL;DR: It is shown that although open-habitat grasses existed in southern South America since the middle Eocene, they were minor floral components in overall forested habitats between 40 and 18 Myr ago, and distinctly different, continent-specific environmental conditions (arid grasslands versus ash-laden forests) triggered convergent cheek-tooth evolution in Cenozoic herbivores.
Abstract: The evolution of high-crowned cheek teeth (hypsodonty) in herbivorous mammals during the late Cenozoic is classically regarded as an adaptive response to the near-global spread of grass-dominated habitats. Precocious hypsodonty in middle Eocene (B38 million years (Myr) ago) faunas from Patagonia, South America, is therefore thought to signal Earth’s first grasslands, 20 million years earlier than elsewhere. Here, using a high-resolution, 43–18 million-year record of plant silica (phytoliths) from Patagonia, we show that although open-habitat grasses existed in southern South America since the middle Eocene (B40 Myr ago), they were minor floral components in overall forested habitats between 40 and 18 Myr ago. Thus, distinctly different, continent-specific environmental conditions (arid grasslands versus ash-laden forests) triggered convergent cheek–tooth evolution in Cenozoic herbivores. Hypsodonty evolution is an important example where the present is an insufficient key to the past, and contextual information from fossils is vital for understanding processes of adaptation.

TL;DR: In this article, Ni/CeO 2 /α-Al 2 O 3 was used to obtain hydrogen by steam reforming of glycerol, and the most stable system resulted in Ni and CeO 2, which can be explained by the Ce effect in inhibition of secondary dehydration reactions forming unsaturated hydrocarbons that are coke precursors.
