ESSAY
| This large animal had long vertebrae along its back, possibly forming a sail. The vertebral spines were 20-30 cm (8-12 inches) high along the neck and tail, possibly up to 50 cm (20 inches) along the back. It was once classified as a spinosaur, since, like Spinosaurus, it had long vertebral spines. But the rest of the animal is little like Spinosaurus, and even the “fin” is different. It may be a late allosaurine or an early carcharodontosaurine. |
