To support his family, Earl works as a tree pusher for the penny-pinching Mr. B.P. Richfield [a three-horned Triceratops] at the ecologically irresponsible, Wesayso Development Corporation. The Sinclair's phone number is 555-3000; Earl's social security number is 000-00-0018.

Earl's family members included:

• Francis "Fran" [née Hinkleman], Earl's 38-year-old Allosaurus  Pisces wife and homemaker who shops at Kave Mart
• Robbie, their rebellious fourteen year old
• Charlene, their shop-crazy 12-year-old
• Baby Sinclair, their bratty infant [he called Earl "Not the Mama"]
• Ethyl Phillips, the nagging 72-year-old Grandma in a wheelchair who calls Earl "Fat Boy"
• Sparky, the family's pet cave girl

For entertainment, the Sinclairs watch TV shows like "Mr Ugh", (about a talking cavemen); "Ask Mr. Lizard" (an educational science show); Raptile." (talk show) and the Dinosaur Shopping Network (Fran's favorite). For a drink (beer) and a night out with the boys, Earl hangs out at the Meteor Tiki Lounge with his best friend Roy Hess [a T- Rex] who lives a carefree bachelor‘s life at a marina condo. Earl is also a member of the YMCA (Young Men's Carnivore Association. For news, Earl reads the Pangaea Tribune.

When the Sinclair family sought spiritual guidance they referred to sacred text called "The Book of Dinosaurs." For instance, when a male dinosaur turned the age of 15, he was required to climb to the top of a mountain and howl at the moon. For as their sacred book said "Only by howling do we defeat the dark spirit which turns dinosaur against dinosaur and brings an end to our days on Earth."

When a dinosaur reached the age of 72, the book advised that family members hurl their useless senior citizens into the tar pits. When mother-in-law Ethyl Phillips reached hurling age, her son-in-law Earl Sinclair gleefully donned a special blue silk tie made for the special event.

TRIVIA NOTE: All of the oversized animatronic dinosaur puppets (that combined computerized animation and live actors) were created by Jim Henson's Creature Shop. Many of the dinosaur's surnames on the show were based on the names of oil companies (Sinclair, Phillips, Hess, Richfield) or the categories of fuels they produced, like Ethyl. In the fall of 1991, the A&E cable channel produced a four-part series entitled DINOSAURS hosted by Walter Cronkite. It was advertised as "the biggest story ever told."
