A Labrador retriever-sized animal that lived 243 million years ago and sported a five foot-long tail may be the oldest dinosaur ever found.

The dinosaur, described in the latest Royal Society Biology Letters, was unearthed near present-day Lake Nyasa in Tanzania. It is named Nyasasaurus parringtoni, which combines the name Nyasa with the term for lizard. The name also honors Rex Parrington, a University of Cambridge paleontologist who first discovered the fossils.

Nyasasaurus walked the Earth about 10 million years before the current oldest dinosaur record holders — such as swift-footed Eoraptor and Herrerasaurus — suggesting that dinosaurs emerged in the Middle Triassic rather than in the latter years of that period.
