I was already impressed with the Prosauropod tooth, but Paul wanted to show me why he' d really bought me to this barren hillside. A leg and rib bone from an entirely different dinosaur. This particular dinosaur is what we think is a new species of large planteating dinosaur, and one that' s actually a close relative of the Sauropod dinosaurs. This animal is quite important because it comes from near the time when the Sauropods started to get very large and actually went down onto all fours. So this animal is walking around on its hind limbs, like most Prosauropods. But it has a number of features that are a bit more like Sauropods. It seems to be, if you like, caught in the act just before it goes down on all fours and becomes a true Sauropod, this seems to be something in the transition between those two grades of dinosaur. This discovery looks like the missing link between the Prosauropods and the fourlegged giants that came later, and Paul seems very sure about what has been found. |
