Scientists in Zimbabwe have found the stays of Africa’s oldest dinosaur, which roamed the earth round 230 million years in the past.

The dinosaur, named Mbiresaurus raathi, was solely about one meter (3.2 ft) tall, with an extended tail, and weighed as much as 30 kilograms (66 kilos), based on the worldwide crew of paleontologists that made the invention.

“It ran round on two legs and had a reasonably small head,” Christopher Griffin, the scientist who unearthed the primary bone, instructed AFP on Thursday.

In all probability an omnivore that ate vegetation, small animals and bugs, the dinosaur belongs to the sauropodomorph species, the identical linage that will later embody big long-necked dinosaurs, mentioned Griffin, a 31-year-old researcher at Yale College.

The skeleton was discovered throughout two expeditions in 2017 and 2019 by a crew of researchers from Zimbabwe, Zambia, and the USA.

“I dug out your complete femur and I knew in that second, that it was a dinosaur and I used to be holding Africa’s oldest identified dinosaur fossil,” mentioned Griffin, who on the time was a Ph.D. candidate at Virginia Tech College.

His crew’s findings have been first revealed in journal Nature on Wednesday.

Dinosaurs’ stays from the identical period had beforehand been discovered solely in South America and India.

The paleontologists chosen the Zimbabwe website for digging after calculating that when all continents have been related in a single land mass referred to as Pangea, it laid roughly on the identical latitude of earlier findings in modern-day South America.

“Mbiresaurus raathi is remarkably much like some dinosaurs of the identical age present in Brazil and Argentina, reinforcing that South America and Africa have been a part of steady landmass through the Late Triassic,” mentioned Max Langer of the College of Sao Paulo in Brazil.

The dinosaur is called after the Mbire district, northeast of Zimbabwe, the place the skeleton was discovered, and paleontologist Michael Raath, who first reported fossils on this area.

“What this (discovery) does is it broadens the vary that we knew the very first dinosaurs lived in,” Griffin mentioned.

Different specimens have been found within the space, and all are reposited within the Pure Historical past Museum of Zimbabwe, within the second largest metropolis, Bulawayo.

“The invention of the Mbiresaurus is an thrilling and particular discover for Zimbabwe and your complete palaeontological discipline,” mentioned museum curator Michel Zondo.

“The truth that the Mbiresaurus skeleton is nearly full, makes it an ideal reference materials for additional finds.”
