Global vegetation dynamics and latitudinal temperature gradients during the mid to Late Miocene (15.97-5.33 Ma)
A 617 site palaeobotanical dataset for the mid to Late Miocene is presented. This dataset is internally consistent and provides a comprehensive overview of vegetational change from 15.97 to 5.33 Ma. The palaeobotanical dataset has been translated into the BIOME4 classification scheme to enable direc...

A 617 site palaeobotanical dataset for the mid to Late Miocene is presented. This dataset is internally consistent and provides a comprehensive overview of vegetational change from 15.97 to 5.33 Ma. The palaeobotanical dataset has been translated into the BIOME4 classification scheme to enable direct comparison with climate model outputs. The vegetation change throughout the Langhian, Seravallian, Tortonian and Messinian is discussed. The data shows that the Langhian, which includes the end of the Mid – Miocene Climatic Optimum, represents a world significantly warmer than today. The high northern latitudes were characterised by cool – temperate forests, the mid – latitudes by warm – temperate mixed forests, the tropics by tropical evergreen broadleaf forests and Antarctica by tundra shrub vegetation. Cool – temperate mixed forest existed during the Seravallian in the high northern latitudes, a reduction in warm – temperate mixed forests in the mid latitudes and a loss of tundra on Antarctica was noted.
