Originally Brontosaurus excelsus, this “Deceptive Lizard” was discovered & described in 1879 in Colorado by Othniel Charles Marsh. It was named such because Marsh thought its lower tail bones to be very similar to a mosasaur, and was thus nearly decieved. Apatosaurus lived during the Late Jurassic Period about 154 to 1... |
