The dinosaur was about as big as a Tyrannosaurus rex and had a unique nasal horn and symmetrical teeth that it used to eat its prey.

Scientists have discovered a new Cretaceous-era dinosaur species by examining photos of a fossil lost during an allied air raid in World World II Munich.

The dinosaur’s fossilized remains were found in 1914 from the Bahariya Formation from a locality in the northern part of the Bahariya Oasis in Egypt. They were first described in 1931 by the German paleontologist Ernst Stromer von Reichenbach, who mistakenly dubbed the species the Carcharodontosaurus saharicus.

Less than a decade later, World War II swallowed Germany. The fossils were housed in the Old Academy building of the Bavarian State Collection for Paleontology and Geology when the campus was hit by air raids on July 21, 1944, completely destroying the wing containing fossils from Egypt, researchers said.
