Cat-sized horses
More than 50 million years ago, the Earth was a hotter place than it is today and horses the size of pet cats roamed the forests of North America, US scientists said on Thursday.
These earliest known horses, known as Sifrhippus, actually grew smaller over tens of thousands of years in order to adapt to the higher temperatures of a period when methane emissions spiked, possibly due to major volcanic eruptions.
The research could have implications for how the planet's modern animals may adapt to a warming planet due to climate change and higher carbon emissions, scientists said.
Researchers made the discovery after analyzing horse tooth fossils uncovered in the western US state of Wyoming that showed the older ones were larger, and that the species had shrunk over time.
