It's been 20 years since Baby Sinclair first uttered the words "Not the mama!"

Yep, it's OK to feel old now.

On April 26, 1991, the world was introduced to the Sinclair family on ABC's 'Dinosaurs.' The sitcom lasted for four seasons and 65 episodes (58 episodes aired during the first run; the remaining aired in syndication) before ultimately ending with the extinction of dinosaurs. (Inevitable, we suppose.)

While 'Dinosaurs' was a sitcom, the show broke the mold by not having a studio audience or a laugh track. Brought to life by a cast of experienced Henson puppeteers and seasoned voice actors, 'Dinosaurs' is heralded as one of the most ambitious sitcoms ever.

The 'Dinosaurs' cast featured many notable sitcom players and voice actors.

Baby Sinclair became a voice of a generation (for a time), spawning merchandise from dolls to T-shirts. The character was voiced and partially moved by Kevin Clash, the voice of Elmo (and Splinter for the first two 'Teenage Mutant Ninja Turtles' films). Clash is also the Muppet captain and co-executive producer of 'Sesame Street.'


Stuart Pankin provided the voice of Earl Sinclair, the patriarch of the family. Pankin went on to provide voice work on 'Animaniacs,' 'Batman Beyond' and 'Duckman.' The actor also booked guest appearances on several of TV's most popular shows, including 'Mad About You,' 'Boston Legal' and 'Curb Your Enthusiasm.' Bill Barretta did the bodywork for Earl. He later went on to create Pepe the King Prawn, Johnny Fiama and Bobo the Bear on 'Muppets Tonight.'

Jessica Walter voiced Fran Sinclair, the mom of the family. The veteran actress later returned to the spotlight as Lucille Bluth on 'Arrested Development,' and can currently be seen on TV Land's 'Retired at 35' and heard as the voice of Malory on 'Archer.' Fran's body was done by Tony Sabin Prince, who also worked on the Henson Company's 'The Country Bears.'


Sally Struthers of 'All in the Family' provided the voice of Charlene, the teenage daughter. After 'Dinosaurs,' the actress voiced a character on 'TaleSpin' and appeared on 'Still Standing' and 'Gilmore Girls.' Charlene's body was done by Michelan Sisti, the same actor who performed Michelangelo in 'Teenage Mutant Ninja Turtles' and 'Teenage Mutant Ninja Turtles 2: The Secret of the Ooze.'

Jason Willinger voiced teenage son Robbie, and post-'Dinosaurs' lent his vocal talents to 'A Goofy Movie.' Leif Tilden did Robbie's body, and went on to play gorillas in 'George of the Jungle,' 'Ace Ventura: When Nature Calls' and 'Buddy.' 'Law & Order: SVU' star Christopher Meloni voiced Robbie's recurring friend, Spike.

Florence Stanley voiced Grandma Ethyl Phillips, mother of Fran. Stanley was an accomplished stage and screen actress when she joined the sitcom, having appeared on Broadway as Yente in 'Fiddler on the Roof' and costarring in 'Barney Miller.' Stanley also provided the voice of Thelma Griffin in 'Family Guy.' She died in 2003 at the age of 79.
