- In Madagascar's sedimentary record, the authors' team unearthed what at first seemed to be the remains of dinosaurs but turned out to be those of an ancient, previously unknown reptile species.
- Its teeth and part of its skull resemble those of prosauropod dinosaurs—precursors of the giant, long-necked sauropods—and suggest that some fea-tures thought to be characteristic of dinosaurs might have debuted earlier than previously thought.
- The team also found fossils of evolutionary cousins of mammals that may have arisen millions of years earlier than assumed.
