Mint. MNH. No flaws. Original undisturbed gum. From a Smoke-free and Pet-free Environment.

On June 8, 1996, the U.S. Postal Service issued these Prehistoric Animals 32¢ gummed stamps in Toronto, Canada. Davis Meltzer of Huntingdon Valley, PA was the artist of these four different stamp designs, featuring four mysterious creatures from the past: the eohippus, wooly mammoth, mastodon, and the saber-toothed cat.

The eohippus roamed North America more than 50 million years ago. This small, horse-like creature was roughly the size of a whippet dog, with four toes on its front feet and three toes on the back. The eohippus is the earliest known ancestor of the family tree of horses that evolved into many creatures we know today, including zebras.

First discovered in drawings on the walls of prehistoric cave dwellings in France and later recovered from the age-old Siberian permafrost, the woolly mammoth is thought to be the ancestor of the Asian elephant. At first glance, the woolly mammoth resembles the present-day elephant, but on closer inspection its differences become apparent. Distinguished by its thick coat of black wool and long drooping "guard-hairs," the woolly mammoth carried large fat deposits on its shoulders and head that scientists believe provided reserve energy for the extreme conditions in which it lived and roamed.

The American mastodon was the last of a long line of diverse elephants that roamed the Earth during the last Ice Age. About the size of current-day Asian elephants, this enormous, gentle species

roamed the continent of North America from Alaska to Florida. Strict vegetarians, these great creatures fed on small shrubs and other bog vegetation. Like their counterpart the woolly mammoth, mastodons disappeared at the close of the last Ice Age, roughly 10,000 years ago.

The saber-toothed cat, boasting large, blade-like canine teeth as long as 6 inches, roamed throughout North and South America. These sleek yet ferocious saber-toothed cats are thought to have preyed on large-bodied mammals such as the offspring of woolly mammoths and mastodons. They, too, became extinct during the last Ice Age.
