By 1992, DIC co-founder Jean Chalopin had left the company, and was looking for a hit series he could call his own. Lee Gunther had left Marvel Productions, ending a run that began with that company's predecessor, DePatie-Freleng. The two of them had a hand in developing an amusing, but short-lived syndicated series, The Adventures of T-Rex, which lasted just 1 season, airing on Sundays in New York and other cities.
T-Rex was the team name of 5 blues singing dinosaurs, whose sister was part of their stage act, but had no clue about their moonlighting as crimefighters. Bearing in mind that this was right before the first "Jurassic Park" movie, you could say this show was ahead of its time. Others can say that Gunther and friends might've had inspiration from "The Blues Brothers", among other things.
Gunther-Wahl Productions, Lee Gunther's new outfit, produced a number of short-lived series during the early 90's, so give them credit for perseverence. Here's the intro, courtesy of CartoonsIntros:
I made the notation at the start because the person who composed the page on Wikipedia for this series assumed, wrongly, that Chalopin was still with DIC at this point. To my knowledge, he wasn't.
