Sadly, the holotype specimen was destroyed after the museum, where the fossils were displayed at, was destroyed by Allied forces during the night of 24/25 April, 1944. Stromer measured the maximum length of Spinosaurus as 12.1 meters (40 ft), despite the holotype measuring only about 10 meters (33 ft) long. The specimen included the lower jaw, teeth, several neural spines, ribs, vertebrae and a single phalanx. The holotype specimen was discovered in 1915 in Egypt, by German paleontologist Ernst Stromer. Spinosaurus is known from several poor specimens.
