Nyasasaurus parringtoni

Fossilised bones unearthed by a British palaeontologist in colonial Tanzania in the 1930s may be those of the oldest dinosaur ever found.  A denizen of the Middle Triassic around 243 million years ago, the creature predates all previous dinosaur finds by 10 to 15 million years. The specimen also points to the possible birthplace of these enigmatic species in Pangaea.
