The "dawn horse" is known by its scientific name, Hyracotherium, which was formerly known as Eohippus. It is not a modern breed in the contemporary sense, but rather the most ancient ancestor of today's horse.
Understanding Hyracotherium (Eohippus)
Hyracotherium, commonly referred to by its older name Eohippus (meaning "dawn horse"), lived during the Eocene era, approximately 55 to 58 million years ago. This small, ancient mammal is considered the earliest known ancestor in the evolutionary lineage of modern horses.
Its significance lies in its foundational role in equine evolution, representing the starting point from which the diverse characteristics of modern horses developed over millions of years.
