I hate to rain on your parade, kindred180, but ranger's can't have dinosaurs as animal companions (unless you can convince your GM otherwise).
From the PRD: "The second option is to form a close bond with an animal companion. A ranger who selects an animal companion can choose from the following list: badger, bird, camel, cat (small), dire rat, dog, horse, pony, snake (viper or constrictor), or wolf."
Sorry. :(
EDIT: Oh, and Acrobatics is already a class skill for animal companions...
Actually, dinosaurs and birds are both filed under the Archosauria clade. so you could consider this loop hole in the rule that "rangers can't have dinosaurs for animal companions." beside it doesn't say they can't have a "distant relative" to birds or a very, very, ancient bird companion.
