I think that might be Denver the last dinosaur.
From Wikipedia:
The show revolves around the adventures of Denver, the eponymous last dinosaur, who was released from his egg by a group of California teens: Jeremy, Mario, Shades, Wally, and Casey, along with tag-along older sister, Heather. The kids taught Denver the finer points of skateboarding and other pastimes while protecting him from rock concert promoter Morton Fizzback who wanted to use the dinosaur to make money.
