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.

Scientists used lost fossil photos to identify Tameryraptor markgrafi, a new dinosaur species from Egypt. The fossil was destroyed in WWII.

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.

What's slightly unusual is that the discovery was made after the uncovering of some long-lost photographs of its fossils. Find out more here.

Paleontologists at the University of Wisconsin-Madison determined a fossil found in 2013 is a new species of dinosaur, the earliest-known dino in the norhtern hemisphere.
