San Francisco Bay Area supergroup The Dinosaurs formed in 1982. The band originally consisted of Peter Albin of Big Brother and the Holding Company, John Cipollina of Quicksilver Messenger Service, Spencer Dryden of Jefferson Airplane, Robert Hunter of The Grateful Dead, and Barry Melton of Country Joe and The Fish.
A number of other prominent San Francisco musicians guested with the group, including Papa John Creach of Jefferson Airplane and Hot Tuna, Jack Casady of Jefferson Airplane, Nicky Hopkins, Dave Getz (Big Brother and the Holding Company), and Country Joe McDonald.
Robert Hunter left the group in 1985 and was replaced by Merl Saunders (ex-the Saunders-Garcia Band).
In 1988, the band released its only studio album, Dinosaurs, and broke up in 1989. John Cipollina died just two weeks after the band’s final concert. A retrospective album, Friends of Extinction, was released on the Evangeline label in 2005.
The band Dinosaur Jr were forced to add the “Jr.” by The Dinosaurs in 1987.
