The sawtooth shark in the dinosaur world, it is the carcharodontosaur known as the last tsar


The Spinosaurus, also known as the "saw-toothed shark" of the dinosaur world, lived in North Africa about 100 million years ago. It was one of the largest theropod dinosaurs, measuring 13 meters in length and weighing six to nine tonnes. Its teeth were very similar to those of a shark, up to 16 centimeters long and flattened, with serrated edges like a dagger. Compared to the Tyrannosaurus rex's robust banana-shaped teeth, the Spinosaurus's bite force was much weaker. It might not have been able to bite through a prey's neck in one bite like the T. rex, but its cutting ability was strong enough to easily tear off a large piece of meat from its prey, and its killing power should not be underestimated. The wounds caused by its bites would bleed profusely. They were good at ambushing prey and launching surprise attacks. While the Spinosaurus's bite may not have been fatal in one blow, it was enough to cause its prey to bleed to death. This hunting method had the advantage of not requiring intense confrontation with prey, as some herbivorous dinosaurs' counterattacks were dangerous, and they were also long-distance runners.


Scientists found that the Spinosaurus had multiple lung sacs that could circulate and reuse air during X-ray imaging of its fossils. This made the oxygen supply to its lungs more efficient, enabling it to run long distances at high speeds, making it better at chasing prey. The Spinosaurus was undoubtedly the top predator of its time. They had a violent temperament and would often fight with their own kind over territory and food. Bite marks from their own kind's teeth have been found on several Spinosaurus skeletal fossils.

At the same time, Africa was also home to another well-known large dinosaur, the Carcharodontosaurus, which was also a large theropod dinosaur that could grow up to 14 meters in length, making it even larger than the Spinosaurus. However, the Carcharodontosaurus primarily preyed on fish and spent most of its time in the water, so the probability of fighting between them was relatively low. But during the dry season when food was scarce, the Carcharodontosaurus would also come ashore to prey on small dinosaurs, and then they were likely to compete for food.
