Brontosaurus is a large plant eating dinosaur related to Apatosaurus but even smaller. It started when a new dinosaur was discovered. He named it Brontosaurus. But then they noticed it was actually a synonom to Apatosaurus. But then in 2013, recent studies show Brontosaurus was actually a real dinosaur, and not a type of Apatosaurus. This spreaded in many articles such as Time For Kids, and Natonial Geographic.
