A statement issued by the medical examiner's office says that Jones complained Wednesday morning that he wasn't feeling well and was having trouble breathing. He was taken to the hospital, where he was pronounced dead. No suspicious circumstances surrounded his death, and his family has been notified. He is survived by his wife, Jessica, and four daughters.
The news was originally reported by TMZ.
Jones was most famous for his role in the pop group The Monkees, which was put together in 1965 for the TV show of the same name. With such hits as "Daydream Believer," "Last Train to Clarksville," "I'm a Believer," and "Pleasant Valley Sunday," and the "Monkees" theme song, the group sold more than 50 million records.
In 2008, Yahoo Music named Jones the top teen idol of all time.
He also acted on stage and screen, with his most famous TV appearance as himself on "The Brady Bunch," in an episode where Marcia Brady was the president of his fan club and tried to get the singer to appear at her school dance. He also played Fagin in "Oliver!" on Broadway.
