O is for Orohippus

A new letter for the Extinct #AnimalAlphabets challenge. This week's animal was Orohippus which is Greek for 'mountain horse'. They lived about 50 million years ago, probably looked like a horse or a donkey, had slim legs, and the bone structure looks like if they were good jumpers, and they had 4 toes on their front legs and 3 on the hind ones.
