So today’s dinosaur is Eoraptor lunensis, literally “dawn plunderer from the Valley of the Moon”. It’s currently considered a basal sauropodomorph (that is, a distant ancestor to the sauropods, or long-necked dinosaurs), though in the past it was considered a theropod. According to one thing I was reading, the reason for the change in classification is from subtle characteristics of the dinosaur’s skeleton. (The two images that follow are of the skeleton, with known material in white, unknown in gray; and an image showing its scale with a human.)
