TLDR
The early Miocene retained the overall humid conditions of the late Paleogene, while the late Miocene as a whole was a time of large changes, and there was continent-wide restructuring of the distribution of environments.Abstract:
Background: We developed a method to estimate precipitation using mammalian ecomorphology, specifically the relative height of the molars of herbivores (see companion paper, this issue) Question: If we apply the new method to paleoenvironments, do the results agree with previous results from fossil mammals and paleobotanical proxies? Data: Large herbivorous fossil mammals of Eurasia Data from NOW database covers 23–22 Ma and is Eurasia-wide Method: We apply the new precipitation estimation method (based on present-day mammalian ecomorphology) to fossil assemblages from different localities Conclusions: The early Miocene retained the overall humid conditions of the late Paleogene A shift to more arid conditions began during the middle Miocene The late Miocene as a whole was a time of large changes, and there was continent-wide restructuring of the distribution of environments Our new results agree with previous investigations and the mammal proxy data are in good agreement with palaeovegetation data Mammals and vegetation produce similar precipitation values and large-scale patternsread more

Ecometric estimation of present and past climate of North America using crown heights of rodents and lagomorphs
TL;DR: The authors used ecometric methods to examine the relationship between rodent and lagomorph crown height and diversity with current climate conditions, finding strong correlations of community structure parameters with climate, particularly mean annual temperature, maximum temperature of the warmest month, and minimum temperature of coldest month.

The living and the fossilized: how well do unevenly distributed points capture the faunal information in a grid?
TL;DR: Grid cells containing fossil localities give good estimates about the total fauna known from all grid cells, especially for relative measures such as community structure.

The Palaeontology of Browsing and Grazing
Juha Saarinen,Juha Saarinen +1 more
TL;DR: This chapter will provide an up-to-date assessment of the analytical methods of determining the diet of extinct large herbivorous mammal taxa, and provide insights into changes in the assemblages of browsing and grazing mammals and how these relate to changes to climate and the evolution of different plant forms.

Plant- and micromammal-based paleoprecipitation proxies: Comparing results of the Coexistence and Climate-Diversity Approach
Jan van Dam,Torsten Utescher +1 more
TL;DR: In this article, a series of 18 sites from the Neogene of Europe and Anatolia that contain both types of fossils, and compare paleoprecipitation predictions produced by the Coexistence Approach (plants) and the Climate-Diversity approach (micromammals).
Book ChapterDOI
Aridity, Cooling, Open Vegetation, and the Evolution of Plants and Animals During the Cenozoic
TL;DR: The development of grassland ecosystems across most continents was a multistage process involving the appearance of open-habitat grasses in the Paleogene, the mid-late Cenozoic spread of C3 grass-dominated habitats, and, finally, the Late Neogene expansion of C4 grasses at tropical and subtropical latitudes as discussed by the authors.

TL;DR: The data support the concept that changes in atmospheric CO2 concentrations, although linked to climate changes, were not the major driving force of Cenozoic cooling.

Climate And Evolution
TL;DR: In this article, the evolution of vertebrate life has been studied in the context of oceanic and coral reef regions in the South-east of the United States, and the effects of different modes of elevritioiis on evolution of terrestrial life have been discussed.

Fossil mammals resolve regional patterns of Eurasian climate change over 20 million years
Mikael Fortelius,Jussi T. Eronen,Jukka Jernvall,Liping Liu,Diana Pushkina,Juhani Rinne,Alexey S. Tesakov,Inesa Vislobokova,Zhaoqun Zhang,Liping Zhou +9 more
TL;DR: Fossil teeth of terrestrial plant-eating mammals offer a new, quasi-quantitative proxy for environmental aridity that resolves previously unseen regional features across the Eurasian continent from 24 to 2 million years ago.

A new global biome reconstruction and data-model comparison for the Middle Pliocene
Ulrich Salzmann,Alan M. Haywood,Daniel J. Lunt,Daniel J. Lunt,Paul J. Valdes,Daniel J. Hill,Daniel J. Hill +6 more
TL;DR: In this article, a robust, comprehensive global biome reconstruction for the Middle Pliocene (c. 3.6-2.6 Ma) is presented, which is based on an internally consistent palaeobotanical data set and a coupled climate-vegetation model.
