Sinclair Dinosaur Gas Station

On U.S. 19 in Spring Hill, Florida, a giant concrete dinosaur looms over the roadside. The former Sinclair Service Station was built in 1964, when Sinclair’s dinosaur logo was already a familiar green mascot for American motorists. Here, the branding escaped the sign and became the building itself.

The creature is usually described as an Apatosaurus or Brontosaurus-like dinosaur, and it is hard to miss: 110 feet long, 30 feet wide, and 47 feet high, with a repair facility tucked inside its body. 

The station eventually became Harold’s Auto Center when local businessman Harold Hurst bought the dinosaur in 1977. The big beast survived long after many roadside novelties vanished, still standing as a wonderfully strange relic of gas-station architecture, brand mythology, and Florida’s talent for making the ordinary enormous. 

In 2020, the Sinclair Service Station was added to the National Register of Historic Places, which means this concrete dinosaur is not just a roadside gag. It is officially historic—a fossil of midcentury car culture hiding in plain sight.
