Massospondylus

One of my favorite dinosaurs is the Massopondylus. It was a plant eater, and stones have been found inside some skeletons, as they swallowed stones to help digest some of the tougher plants that they ate. They stood about 13 feet tall and walked on two feet, but when they were born they first walked on all fours. Like human babies, in a way, they started crawling and then learned to walk upright. They had hands with five fingers. They were around as early as 190 million years ago and were around for a good 40 million years or so. 40 million years and they never caused any trouble.... I thought they were rather cute actually.
