James Belushi apparently turned down the role of Earl Sinclair to pursue a movie career.
The Dinosaurs family name Sinclar is a reference to the Sinclair Oil Corporation, which has prominently featured a dinosaur as its logo and mascot for decades, under the now-rejected belief that petroleum deposits were formed during the age of the dinosaurs.
Other character and family names throughout the series often referred to rival petroleum companies and/or petroleum products.
When Fran and Earl spell out words in front of Baby during an argument, Baby looks at the camera, saying: “This could get ugly”.
He then proceeds to spell out the words, “They think I can’t spell” (with his alphabet blocks).
Because of the popularity of Baby the network allowed the creators to run the show pretty much as they saw fit.
Baby would repeatedly batter his father with a frypan, yelling out: “Not the mama!”
“As long as the Baby hit his father over the head with a pot, we could use that to hide anything.”
According to makers, Touchstone Television (owned by Disney) constantly pressured them into making budget cuts, which they couldn’t accommodate due to the high demands of combining live action with puppet animation.
Disney finally pulled the plug in the fourth season, citing that the show had become too expensive.
The final episode of Dinosaurs produced and aired on ABC, Changing Nature, was intended as the series finale and depicts the irresponsible actions of the dinosaurs toward their environment, and the ensuing Ice Age which leads to their demise.
Not surprisingly, Touchstone originally did not air the episode, but it was later broadcast in syndication.
