Primeval Whirl was built by France's Reverchon company. They have built about two dozen coasters.
Reverchon started in 1927 when Gaston Reverchon created his own workshop near Paris. He intended to work on cars, but he soon found himself building dodgem cars for amusement parks. Gaston died in 1982 at the age of 81, but his company continues to build coasters, log flumes, and other entertaining rides.
