The first discovery
Egypt, 1912: Stromer's Spinosaurus
German paleontologist Ernst Stromer von Reichenbach led an expedition to the Bahariya Oasis in western Egypt. Between 1911 and 1914, his team uncovered partial remains of a large, unusual theropod with elongated dorsal vertebrae forming a distinctive “sail.” Stromer named it Spinosaurus aegyptiacus — the “Egyptian spine lizard.” He recognized it as something new: a giant predator with adaptations unlike any known dinosaur. His publication in 1915 described conical teeth, a long narrow snout, and the towering neural spines that made Spinosaurus instantly iconic.
