Stomatosuchus inermis, a huge crocodylomorph from the Late Cretaceous of Egypt, living about 100-94 million years ago. Estimated to have been up to 10m long (~32′10″), it had an unusually long and flat head, with the upper jaw lined with hundreds of tiny conical teeth. Exactly what it ate with such a strange mouth is unknown, but the shape of its lower jaw suggests it may have had a large throat pouch – perhaps filter-feeding somewhat like modern baleen whales.
Only one fossil has ever been found, a single large skull which was kept in the Munich Museum. Unfortunately, in 1944 the museum was severely damaged in an Allied bombing raid, and Stomatosuchus was among the specimens destroyed – along with the original material of the much more famous Spinosaurus.
