Most of the characters' names are of petroleum corporations (Sinclair, Hess, BP, Phillips).

The news anchor seen in several episodes is named "Howard Handupme." This is a reference to the fact that he is a hand puppet.

Earl often sighs as he walks across a room. This allowed the person inside the costume a chance to see where he was going. He could onlt see through the open mouth.

Seven episodes that did not air in prime time aired when the show went into syndication.

Jim Henson originally got the idea of a live action show featuring animatronic dinosaurs after he was impressed by the technology his Creature Shop was developing for the first Teenage Mutant Ninja Turtles film. When the show went into production, the same technology was used to create the Dinosaurs. Many of the Ninja Turtle suit actors worked as various Dinosaur suit actors for the series.

A feature film spin-off was planned during the fourth season. But the show's falling ratings resulted in the cancellation of the show and the planned film.

Jim Belushi turned down the role of Earl Sinclair, wanting to pursue a film career,

Earl's middle name is Sneed. Robbie's middle name is Mark.

Another reason for the dinosaur family name to be Sinclair is that when the Sinclair oil company was still in existence, its gas stations had as their logo the image of a green four-legged dinosaur (the brontosaurus or apatosaurus.)

In many episodes, the rock band "Lizzard Skizzard" is on TV. The name is an obvious reference to Lynyrd Skynyrd, but they have more in common with 1980s-90s "hair bands."

The Simpsons: Black Widower (1992) features a parody of this show, and implies that it's a rip-off of The Simpsons (1989). Jim Henson conceived of the idea before the "The Simpsons" aired. His idea was deemed too weird until the popularity of that series.

Earl is 43. Fran is 38. Robbie is 14. Charlene went from 12 (mentioned from season 1 and 2) to 15 (mentioned in season 4). Baby went from 1 to 2, but because of his terrible attitude, the family convinced him he had turned 3. Mr. Richfield is 42.

Grandma Ethyl's maiden name is Hinkleman.

When the Disney Channel aired reruns in the late 1990s and early 2000s, three episodes were not shown: Dinosaurs: What 'Sexual Harris' Meant (1991), Dinosaurs: Baby Talk (1992), and Dinosaurs: Dirty Dancin' (1993).

The initial design for Grandma Ethyl Phillips was a pterosaur. A winged creature, she was always to be shown hanging upside down, usually in a closet. The design was extremely difficult to manipulate, so it was changed to the design seen in the series.

The full-size dinosaur costumes came in two parts, a full body suit and a separate animatronic head. The head contained radio-controlled motors that moved the jaw, lips, eyes, and eyebrows. For closeup speaking and lip-sync, the heads were separated and operated by a team of puppeteers.

There were plans at one point early on to use the animatronic suits made for the Teenage Mutant Ninja Turtles and Bart Simpson to appear in the show, most likely as a show seen on the TV within the show, but due to copyright were not able to be implemented.

Robbie and Charlene go to Bob Labrea High School, where the team mascot is The Rampaging Trilobites.

Very little merchandise was created for the show. A handful of small plastic figurines were produced and given away with McDonald's Happy Meals. A Baby Sinclair plush doll was also produced.

Jim Henson's Creature Shop designed the Dinosaur's animatronics with the requirements of a long-running series in mind. They were engineered to be far more robust and easy to maintain than would be necessary for a film.

A video game for the Super Nintendo was in negotiations in 1993. Several games based on TV shows were developed during the time, but received poor reviews as they had nothing to do with the shows and were only using the name during this fad. By the time it came to negotiating a deal for Dinosaurs, the fad had worn off and negotiations were dropped along with a board game too.

It is speculated that Earl Sinclair may had been modeled after actor Ernest Borgnine.

In "Dinosaurs: Earl's Big Jackpot (1994)," it was revealed that Mr. Richfield's first name is Bradley.

None of the Sinclair family has the same coloured eyes.

A board game based on the TV show called "Dinosaurs. Gotta Love Me!" by Milton Bradley was published in 1991.

As of 2016, this remains one of four former TGIF sitcoms to have the entire series released on DVD. The others are Full House (1987), Boy Meets World (1993), and Sabrina, the Teenage Witch (1996).

During production of the 10th show of Season 4, Kevin Clash, in character as Baby Sinclair got cranky during film causing cast and crew to crack up laughing.

In the Sinclair family's living room, a painting of a crying infant dinosaur hanging on the wall is meant to parody "The Crying Boy", the allegedly-haunted painting by Italian artist Bruno Amadio (1911-1981).

The Baby character was called "the baby" or Junior during the first two seasons. In Dinosaurs: And the Winner Is... (1992), Baby Sinclair is taken to the Cave of the Elders, where he is given his official name Ooh Ooh Ah Ah I'm Dying You Idiot Sinclair. The name was later exchanged for his new official name: Baby Sinclair.
