Spinosaurus Aegyptiacus

The Spinosaurus Aegyptiacus was a large carnivorous dinosaur, distinguishable for its crocodilian jaw and the large sail believed to have protruded from its back. This sail was supported by bone protrusions from the vertebrae and may have been used as a sexual display, similar to a peacocks tail. As such it may have been brightly colored or flushed with blood.

The Spinosaurus lived in North Africa and, at 16-18 meters (52-59ft) and weighing up to 10 tons, is the largest carnivorous dinosaur ever discovered. As such it is possibly the largest carnivorous land animal to have ever existed. It is believed that it died out in the early cretaceous period. However, a lack of evidence makes any supposition about this creature difficult.

The Spinosaurus Aegypticus (or 'Egyptian Spine Lizard') was discovered by German paleontologistErnst Stromer who unearthed its skeleton in the Egyptian desert in 1912. Unfortunately, many of the bones were damaged in transit to Germany and later the remaining bones were destroyed by an Allied bombing raid during World War II. The lack of material evidence pertaining to the Spinosaurus, combined with its unlikely size and appearance, has cast doubt over its existence for many years. However, recent finds in Morocco are believed to be of the same species or a closely related subspecies.
