SNSB and LMU Paleontologists identify a new species of predatory dinosaur from the Cretaceous period in North Africa, around 95 million years old. What makes this discovery so special is that the original fossil from Egypt was completely destroyed 80 years ago, during World War II.<\/em> For their work, the researchers analyzed previously unknown archival photographs of the dinosaur skeleton from the period before 1944. The findings are published in the scientific journal PLOS ONE<\/em>.<\/em><\/em><\/p>\n\n\n\n

The fossil’s eventful history stretches far back into the past: the original skeleton of the large predatory dinosaur was described by the Munich paleontologist Ernst Stromer von Reichenbach (1871-1952). It was excavated in 1914 during an expedition in the Bahariya Oasis in Egypt and was sent to Stromer in Munich shortly after. There it was stored together with other Egyptian dinosaur fossils in the Bavarian State Collection for Paleontology and Geology, which at that time was located in the Old Academy in the center of Munich. Stromer assigned the fossil to the genus Carcharodontosaurus<\/em>, shark-toothed lizard. At around ten meters long, it was one of the largest known land-based carnivores in the history of the earth \u2013 comparable in size to the slightly younger Tyrannosaurus rex<\/em> from North America.<\/p>\n\n\n\n

On July 21, 1944, the Old Academy building was hit by an allied air raid on Munich and completely burnt out. A large part of the collection at the time, including all Egyptian dinosaur fossils, fell victim to the bombing. After that, it was quiet around the giant Egyptian predator for a long time and the finds were forgotten. The only remnants of the Cretaceous dinosaurs of Egypt are Stromer’s notes, illustrations of the bones and a few photos of the original skeletons.<\/p>\n\n\n\n

During new research, the paleontologist Maximilian Kellermann, a master’s student at the LMU M\u00fcnchen, came across new, previously unknown photos of the predatory dinosaur. The pictures show the original skeleton from Egypt \u2013 parts of the skull, spine and hind limbs \u2013 before its destruction in the exhibition at the Alte Akademie. Kellermann evaluated the new images together with dinosaur specialist Prof. Oliver Rauhut from the Bavarian State Collection for Paleontology and Geology (SNSB-BSPG) and Dr. Elena Cuesta from LMU.<\/p>\n\n\n\n

\u201cWhat we saw in the historical images surprised us all. The Egyptian dinosaur fossil depicted there differs significantly from more recent Carcharodontosaurus<\/em> finds in Morocco. Stromer’s original classification was thus incorrect. We identified a completely different, previously unknown predatory dinosaur species here and named it Tameryraptor markgrafi<\/em>,\u201d says Maximilian Kellermann, first author of the study.<\/p>\n\n\n\n

Tameryraptor<\/em> was about ten meters long, had symmetrical teeth and a prominent nasal horn. The name refers to the ancient name for Egypt, \u201cTamery\u201d, the promised land, and honors Stromer’s fossil collector Richard Markgraf, who excavated this dinosaur remains. The researchers found that the dinosaur was closely related to the North African and South American Carcharodontosaurs, as well as to a group of predatory dinosaurs from Asia, the Metriacanthosaurs.<\/p>\n\n\n\n

\u201cPresumably, the dinosaur fauna of North Africa was much more diverse than we previously thought. This work shows that it can be worthwhile for paleontologists to dig not only in the ground, but also in old archives,\u201d says Oliver Rauhut. \u201dHowever, a more comprehensive assessment of the Cretaceous predatory dinosaur fauna from the Bahariya Oasis would require the recovery of more fossils from the site.\u201d<\/p>\n\n\n\n
