Scientists talked about the anatomical details, as well as the lifestyle of the spinosaurus. As it turned out, this large dinosaur (spinosaurus reached a length of 15 m) led an amphibian lifestyle.

Its remains found in Morocco helped to learn about the habits of a spinosaurus. The spine, skull, pelvic girdle and lower limbs were found. Then a team of scientists led by Nizar Ibrahim created a three-dimensional model based on the data obtained.

The main conclusion of the study was that the giant lizard led a semi-aquatic lifestyle and ate, among other things, marine life. The dinosaur used its huge tail as an oar, and the nostrils shifted to the middle of the crocodile's skull helped the creature to submerge in water for a long time. Giant teeth were located at the front of the head, allowing the dinosaur to fish. Sharks and ancient gigantic fish could be included in the main "menu" of the lizard.

The center of gravity of the spinosaurus was shifted forward - because of this, it was difficult for him to walk, but it was much easier to swim. The webbed feet of the creature made it possible to easily row in the water, as well as move around wetlands. On land, as far as can be judged, the Spinosaurus moved on four legs.

As it turned out, the famous "sail" of the spinosaurus could not have served for thermoregulation, as was previously thought, but had decorative functions. To prove this, the emphasis is placed on the fact that such a "sail" was clearly visible even when submerged in water. This part of the lizard's body was also covered with skin.

Scientists note that the transition of a large predatory lizard to an amphibian lifestyle is almost a unique phenomenon. Spinosaurus has already been called the "evolutionary experiment."
