I travelled to various museums in India to study the fossils of extinct mammals that lived in India between 3.5 and 0.5 million years ago. I measured the teeth of these species and used the measurements to estimate how large they were when they lived. I found that as the climate cooled and the ecosystems become dominated by grasslands, smaller herbivorous mammals went extinct while more large species migrated into the Subcontinent, a finding consistent to what we expect when the climate cools and becomes more arid. I was also fortunate enough to identify a type of horse that was previously unknown from South Asia and was only thought to have lived in Africa.
