What features of Hyracotherium show that it is related to horses?
They both have similar skull features such as, shape, space between front and back teeth.
Who discovered the Hyracotherium?
In 1876, Othniel C. Marsh found the full skeleton in America, which he named Eohippus (“dawn horse”). When it became clear that the two finds were closely related, the first published name (Hyracotherium) became official and Eohippus came to be a synonym.
Where was the Hyracotherium found?
Small size and multi-toed feet kept Hyracotherium from sinking into the swamp. The remains of this original little horse have been found in such places as the Wasatch Range in Utah, the Wind River Basin in Wyoming, and in Europe.
Where was the first Hyracotherium fossil found?
The first fossil identified as being of this genus, holotype specimen BMNH M16336, was found in the cliffs of Studd Hill near Herne Bay, Kent, and described by the paleontologist Richard Owen in a paper read to the Geological Society of London on 18 December 1839 as a “small mutilated cranium about the size of that of …

What environment did the Mesohippus live in?
Fossils of Mesohippus are found at many Oligocene localities in Colorado and the Great Plains of the US, including Nebraska and the Dakotas, and Canada. This genus lived about 37-32 million years ago. Mesohippus are browsing in their forest habitat in this 1913 painting by Bruce Horsfall.

How big is the Hyracotherium?
Compared to living horses, Hyracotherium was a lot smaller: it usually measured half a metre or less (1.5 ft.) in length—about the size of a fox terrier. Also, it had a more-complete series of teeth than modern horses, which were used for feeding on soft, leafy vegetation.
What size is the Hyracotherium?
Hyracotherium was a form close to the common ancestry of all the odd-toed hoofed mammals, the perissodactyls. It stood 30–60 cm (1–2 feet) high at the shoulder, depending on the species. The skull varied in length; some species had a relatively short face, but in others the face was long and more horselike.
What are differences between Mesohippus and modern horse?
Mesohippus was slightly larger than Epihippus, about 610 mm (24 in) at the shoulder. Its back was less arched, and its face, snout, and neck were somewhat longer. It had significantly larger cerebral hemispheres, and had a small, shallow depression on its skull called a fossa, which in modern horses is quite detailed.
Where are the fossils of Hyracotherium found?
Fossils of Hyracotherium are found at many Eocene localities in the western US and Europe. Species in this genus lived from around 55 million years ago to around 45 million years ago. When those fossils were discovered, Hyracotherium was thought to be a monkey.
How big was the Hyracotherium compared to a horse?
It is only known as one of the ancestral relatives of the modern horse and not the first ancestral relative. Looking at Hyracotherium pictures, you can clearly see an animal which was extremely small as compared to modern horses or even modern humans. They were about 2 feet high, was about 2 feet long and weighed all of 50 pounds.
Is the Hyracotherium the same genus as Eohippus?
Paleontologists later determined that eohippus was really the same genus as Hyracotherium and based on scientific procedure, the older name Hyracotherium (1840) takes precedence over, and includes, eohippus (1876). Hyracotherium had 4 toes on the front foot, and 3 toes on the hind foot. Hyracotherium reconstruction by Charles Knight.
Why was the Hyracotherium had a striped coat?
The great science artist Charles Knight of the American Museum of Natural History reconstructed Hyracotherium with a striped coat because it was a browsing horse. Browsing animals we know today often have striped coats to camouflage them in the play of light and dark on the forest floor.
