MANSOURA, Egypt— A skeleton has been unearthed in Egypt’s Western Desert, where ancient sands have long helped preserve remains, but unlike most finds this one isn’t a mummy—it’s a dinosaur.

Researcher­s from Mansoura University in the country’s Nile Delta discovered the new species of long-necked herbivore, which is around the size of a city bus, and it could be just the tip of the sand dune for other desert dinosaur discoverie­s.

“As in any ecosystem, if we went to the jungle we’ll find a lion and a giraffe. So we found the giraffe, where’s the lion?” said Hesham Sallam, leader of the excavation team and head of the university’s Center for Vertebrate Paleontolo­gy.

Sallam, along with four Egyptian and five American researcher­s, authored an article in the journal Nature Ecology & Evolution published Jan. 29 announcing the discovery.

Experts say the find is a landmark one that could shed light on a particular­ly obscure period of history for the African continent, roughly the 30 million years before dinosaurs went extinct, between 70 million and 80 million years ago.

Named “Mansourasa­urus Shahinae” after the team’s university and for one of the paleontolo­gy department’s founders, the find is the only dinosaur from that period to have been discovered in Africa, and it may even be an undiscover­ed genus.

In the article the authors say the team’s findings “counter hypotheses that dinosaur faunas of the African mainland were completely isolated” during the late Mesozoic period. Those theories were that Africa’s dinosaurs during that time existed as if on an island and developed independen­tly from their northern cousins.

But Mansourasa­urus’ fossilized skeletal remains suggest an anatomy not very different from those discovered in Europe from the same period, an indication that a land connection between Africa and its northern neighbor may have existed.

The news was welcomed by other paleontolo­gists, who now see the desert to the west of the Nile as fertile ground for new informatio­n about the Earth’s former residents.
