If you've ever seen The Lion King 1 1/2 you'd know that he has to be a Meerkat because he lives with his Meerkat clan at the beginning. Also, the beginning of this movie begins in the Meerkats native range but after an incident he caused with hyenas, Timon travels to wherever the original movie took place (well actually to that jungle place). The movie also reveils that when all the animals bowed for Simba in the first movie, they were really fainting at Pumbaa's farts
You could say that pretty much the entire Jurassic Park movies were zoological movie malpractice because many of the animals didn't really live together (very few were actually from the Jurassic in the 1st movie) and they exagerated the sizes for some of the animals (i.e. the Velociraptors). Also, as far as I know of, Brachiosaurus couldn't stand on their hind legs.
The fact that they use modern food, medical practices, and techniques on the Extinct animals in Prehistoric Park could also be viewed as such. Not to mention the fact that they had a Woolly Mammoth as part of an African Bush Elephant herd.
