Eohippus sp.
Age: Eocene
Fossil Site: Green River Formation, Uintah County, Utah
Size: 45 mm on 120 mm x 110 mm matrix
Fossil ID: VFS015
Price: $125 - sold
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"). |

Brontotherid and bird Trackway
Taxonomy: Class Mammalia, Order Perissodactyla, Brontotheriidae
indet.
Age: Eocene
Size: 60 mm on 180 mm x 185 mm matrix
Fossil Site: Green River Formation, Uintah County, Utah
Fossil ID: VFS016
Price: Sold
Remarks: This is an unusually small Brontotherid track and
therefore a baby.This is 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. |

Fossil Lizard Tracks
Geological Time: Eocene
Fossil Site: Green River Formation, Sevier County, Utah
Size: 190 x 120 mm matrix
Fossil ID: VFS017
Price: $95
Remarks: Eocene lizard tracks are very rare. Most probably,
the area was a near-shore shelf along Uinta Lake that existed
during the Eocene. |

Fossil Site: Green River Formation, Sevier County, Utah
Size:
Fossil ID: VFS018

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: VFS019
Price: $125
Remarks: The second track at the lower left is split through
the center and is missing much detail. The other at top right
is 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
