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 Lizard Track & Invertebrate track
Geological Time: Eocene
Fossil Site: Green River Formation, Sevier County, Utah
Size:
Fossil ID: VFS018
Price: $75
Remarks: Eocene lizard tracks are very rare. The invertebrate trail may be a worm. Most probably, the area was a near-shore shelf along Uinta Lake that existed during the Eocene.
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 elephant by the Oligocene, only to become extinct by the end of the Oligocene with the proliferation of grasslands.
