I'm looking for a children's movie that is a cartoon that has a father who is an inventor. His kids played with his car like time machine which brought them back to the dinosaur time, when they came back they accidentally brought back a small dinosaur that looked like a fuzzy elephant. He had with him eggs that he kept in his mouth and when they finally hatched they were baby versions of him. At the end of the movie they realized he couldn't stay with them because he belonged in his time with the other dinosaurs and the baby versions of him. Please help me any type of information would be awesome.
