Brontosaurus Was A Dinosaur
For over 100 years, the Brontosaurus wasn’t really considered a dinosaur. In 1879, Paleontologist Othniel Charles Marsh classified it as Apatosaurus because it shared some similarities with another specimen he had found 2 years prior. But in 2015, a study discovered that the two fossils were inherently different. So much so, that they belonged to two different categories, so now we know that the Brontosaurus is actually a dinosaur after all.
