Answer:The Mbiresaurus rather lived more than 230 million years ago, researchers said. The Mbiresaurus rather was about 6 feet long, had a long tail, and weighed anywhere from 20 to 65 pounds. The Mbiresaurus rather is considered a sauropodomorph, a long-necked dinosaur.
Step-by-step explanation:The newly-described fossil found decades ago in Tanzania extends the dawn of the dinosaurs more than 10 million years further back in time. Named Nyasasaurus Barrington, the roughly 243-million-year-old fossils represent either the oldest known dinosaur or the closest known relative to the earliest dinosaurs.
