Over 60 million years ago, I am a Hyracotherium that existed in North America and Europe. Compared to the modern horse, I had an arched back and raised hindquarters. My legs ended with padded feet with four functional hooves. My brain was far less complex and smaller, compared to the modern horse who had a large flexible muzzle.
I use my omnivorous teeth with short bumpy molars to eat
My teeth gradually changed to herbivorous mammals. They became long, rough, cubical molars.
I am a Equus modern horse. I am a lot bigger than a Hyracotherium, their is different types of me like a heavy horse, a pony and a light horse.
