New Jersey Earth Symbols

New Jersey, North Dakota, and Pennsylvania were long the only states without an official mineral, rock, stone, or gem. However, New Jersey joined the party in 2023 when franklinite was declared the official state mineral.

Though rare worldwide, franklinite is often found in the northwest portion of New Jersey. Indeed, franklinite was the foundation of a booming mining industry in the 19th and 20th centuries. Of course, it isn’t hard to guess how it ended: the ore was eventually depleted. However, franklinite is still sought by collectors.

Franklinite was named after its local discovery at the Franklin Mine and Sterling Hill Mines in Franklin, New Jersey. Today, Franklin is known as the “Fluorescent Mineral Capital of the World.” In fact, it is located over a rich ore body containing more than 150 minerals, some of which are found nowhere else.

Brownstone is considered New Jersey’s unofficial stone.

The real show stopper is New Jersey’s state dinosaur, Hadrosaurus foulkii.

The story begins about the middle of the 19th century, when workers found some gigantic bones in a marl pit in Haddonfield, New Jersey. Some 20 years later, in the summer of 1858, William Parker Foulke was vacationing in Haddonfield when he heard stories about the giant bones.

Curious, Foulke hired a crew to excavate the pit. What they discovered was a shock: the first nearly-complete skeleton of a dinosaur!

Today, local sports teams call themselves the Haddonfield Bulldogs, not the Haddonfield Hadrosaurs. But Hadrosaurus foulkii is widely known as America’s first dinosaur.

Soil ˆ

Downer is the Garden State’s unofficial state soil.

Formed in loamy fluviomarine deposits in the Northern Atlantic Coastal Plain, Downer soils are popularly are used for growing field crops, vegetables, flowers, and some tree fruits.
