Announced March 12th:

With this pane of 16 stamps, the Postal Service brings Tyrannosaurus rex to life — some 66 million years after its demise. One design illustrates a face-to-face encounter with a T. rex approaching through a forest clearing; another shows the same young adult T. rex with a young Triceratops — both dinosaurs shown in fossil form. The third and fourth stamps depict a newly hatched T. rex covered with downy feathers and a bare-skinned juvenile T. rex chasing a primitive mammal. The “Nation’s T. rex,” the young adult depicted on two of the stamps, was discovered on federal land in Montana and is one of the most studied and important specimens ever found. Its remains will soon be on display at the Smithsonian Institution’s National Museum of Natural History in Washington, D.C. Art director Greg Breeding designed the stamps with original artwork by Julius T. Csotonyi, a scientist and paleoartist.

These stamps will be issued August 29, 2019 in Washington DC. Further updates will appear below, in order announced.

The Scott catalogue numbers for this issue are 5410-5413.

Background:
Tyrannosaurus rex dominated the tail end of the dinosaur age. A recent surge in discoveries has revolutionized our understanding of the fierce carnivore.

Four dynamic designs on a pane of 16 stamps depict the awe-inspiring dinosaur in growth stages from infancy to adulthood.

One design illustrates a face-to-face encounter with a T. rex approaching through a forest clearing; another shows the same young adult T. rex with a young Triceratops — both dinosaurs shown in fossil form.

The third and fourth stamps depict a newly hatched T. rex covered with downy feathers and a bare-skinned juvenile T. rex chasing a primitive mammal.

“The Nation’s T. rex,” the young adult depicted on two of the stamps, was discovered on federal land in Montana and is one of the most studied and important specimens ever found. Its remains are now exhibited at the Smithsonian Institution’s National Museum of Natural History in Washington, DC. Art director Greg Breeding designed the stamps with original artwork by scientist and paleoartist Julius T. Csotonyi.

The Tyrannosaurus Rex stamps are being issued as Forever stamps. Forever stamps will always be equal in value to the current First-Class Mail
1-ounce price.

Customers may purchase stamps and other philatelic products through The Postal Store at usps.com/shop, by calling 800-STAMP24 (800-782-6724), by mail through USA Philatelic or at Post Office locations nationwide.
