Brontotherid Tracks
Taxonomy: Class Mammalia, Order Perissodactyla, Brontotheriidae
indet.
Age: Eocene
Size: 185 mm x 155 mm matrix
Fossil Site: Green River Formation, Uintah County, Utah
Fossil ID: VFS020
Price: $195
Remarks: This specimen has a rear track superimposed on the
front track. This an excellent ichnofossil from the Green
River Formation of Sevier County, Utah that belonged to a
large mammal know as a brontothere. While they looked somewhat
like a rhinoceros, they were more closely related to horses.
Brontotheres were browsers in warm temperate to subtropical
environments and ranged from forest to open woodland. They
evolved rapidly from their Eocene members to ones rivaling
the size of the elephant by the Oligocene, only to become
extinct by the end of the Oligocene with the proliferation
of grasslands. This fine track provides a brief glimpse of
a moment frozen for all time for some 50 million years when
this massive animal walked across a muddy surface. |

Brontotherid Tracks
Taxonomy: Class Mammalia, Order Perissodactyla, Brontotheriidae
indet.
Age: Eocene
Size: 125mm,130mm mm on 325 mm x 290 mm matrix
Fossil Site: Green River Formation, Uintah County, Utah
Fossil ID: VFS021
Price: $295
Remarks: This is an excellent negative/positive ichnofossil
track from the Green River Formation of Sevier County, Utah
that belonged to a large mammal know as a brontothere. The
print is that of the front foot and is one of the best specimens
I've seen. While they looked somewhat like a rhinoceros,
they were more closely related to horses. Brontotheres were
browsers in warm temperate to subtropical environments and
ranged from forest to open woodland. They evolved rapidly
from their Eocene members to ones rivaling the size of the
elephant by the Oligocene, only to become extinct by the
end of the Oligocene with the proliferation of grasslands.

Eohippus sp.
Age: Eocene
Fossil Site: Green River Formation, Uintah County, Utah
Size: 45 mm on 110 mm x 90 mm matrix
Fossil ID: VFS022
Price: $45
Remarks: This plate contains the extremely rare track of
Eohippus (meaning "dawn horse"), the earliest known
horse. Also called Hyracotherium, this grazing herbivore
was the size of a small dog. It had 4 hoofed toes on the
front feet and 3 hoofed toes on the hind foot. However, the
fourth toe on the front foot was higher on the foot and is
not likely to leave an impression. Eohippus lived during
the early Eocene Epoch, about 50 million years ago and ranged
across Asia, Europe, and North America. Fossils were first
discovered by the famous British paleontologist Richard Owen
in 1841 who named it Hyracotherium (meaning "mole beast"). |
