The Sinclair dinosaur toy is a piece of American pop culture history. Sinclair Oil Corporation adopted the Apatosaurus (commonly called Brontosaurus) as its mascot in 1930, and “Dino” the green dinosaur has been a beloved advertising icon ever since. Vintage Sinclair dinosaur toys — especially the inflatable green Brontosaurus figures given away at gas stations during the 1960s — are now highly sought-after collector items worth serious money.

History of the Sinclair Dinosaur

Sinclair Oil chose the Apatosaurus (then called Brontosaurus) as their mascot to symbolize the ancient origins of petroleum — crude oil forms from organic matter millions of years old, just like the age of dinosaurs. The green dinosaur logo became one of the most recognizable brand mascots in American history.

The Sinclair dinosaur reached peak fame at the 1964 New York World’s Fair, where Sinclair sponsored “Dinoland” — a massive exhibit featuring life-size animatronic dinosaurs. Millions of visitors received free inflatable Sinclair dinosaur toys, creating a generation of collectors. Those World’s Fair inflatables are now the most coveted Sinclair dinosaur collectibles.

Frequently Asked Questions

What is the Sinclair dinosaur toy?

The Sinclair dinosaur toy refers to promotional dinosaur figures — most famously the green inflatable Brontosaurus — given away by Sinclair Oil Corporation at gas stations and the 1964 World’s Fair. These are now collectible items valued for their Americana significance and nostalgic appeal.

How much are Sinclair dinosaur toys worth?

Values vary widely: common small plastic Sinclair dinosaur figures sell for $5–$15 each. Complete figure sets fetch $30–$75. The iconic 1964 World’s Fair inflatable Brontosaurus ranges from $30 (used) to $200+ (mint with packaging). Rare promotional items like ceramic banks can exceed $100.

What kind of dinosaur is the Sinclair mascot?

The Sinclair mascot is an Apatosaurus, historically called Brontosaurus. It’s a large, long-necked herbivorous dinosaur from the Jurassic period. Sinclair chose this species in 1930 to represent the ancient origins of petroleum. The green color is a branding choice, not based on the actual animal’s appearance.

Why did Sinclair Oil use a dinosaur?

Sinclair adopted the dinosaur mascot to promote the idea that their motor oil came from prehistoric sources — linking crude oil’s ancient origins to the age of dinosaurs. While this is a simplification (petroleum mostly comes from ancient marine organisms, not dinosaurs), it created one of the most memorable brand mascots in American advertising history.

Are Sinclair dinosaur toys still being made?

No — original Sinclair dinosaur promotional toys haven’t been produced since the 1980s. Any Sinclair dinosaur toys available today are vintage collector items. However, modern Apatosaurus and Brontosaurus figures from brands like Safari Ltd and Schleich capture the same look at affordable prices.
