The history of dinosaur evolution will be rewritten. So researchers say after discoveries made during the study of discovered fossil animals. Palaeontologists have identified unique swimming devices in land dinosaurs. It is worth paying attention to the fact that scientists always oppose the idea that dinosaurs supported the aquatic environment. In support of the fact that ancient animals could not live in water, they give a huge amount of evidence.
But they all crashed on the results of recent scientific research related to the discoveries of an international team of researchers supported by the National Geographic Society. Researchers have evidence that the largest predator dinosaur known to science used its tail to swim and hunt aquatic creatures.
And this is the first in the scientific evidence of such an adaptation of ancient animals. Researchers made their conclusions based on the only spinosaurus skeleton in the world. It was discovered in the Kemk region in Moroccan Sahara. The skeleton is also currently the most complete and well-preserved for the predatory dinosaur from the Cretaceous period.
Palaeontologist Nizar Ibrahim has been studying the skeleton since 2008. In the past, a spinosaurus was identified as a dinosaur eating fish with amphibian adaptations. He had relatively short hind limbs, wide feet, firm bones, and elongated jaws dotted with conical teeth.
However, the suggestion that it could be a truly aquatic dinosaur was met with significant opposition, largely because the skeleton provided little evidence that a moving structure was needed to move such a giant dinosaur through the water. Over the past five years, a group of scientists has discovered other fossilized remains of the skeleton of a spinosaurus, including its amazing ribbed tail.
A created computer model showed that such a tail with extremely long spikes had the ability to extensive lateral movement, and could serve as an excellent blade for movement in the water. To quantify the effectiveness of the tail, a Harvard research team made a flexible model and attached it to a robotic system that simulates swimming movements. Then they compared the swimming characteristics of the tail of the spinosaurus model with the models of the tails of other animals, including crocodiles, newts.
The results are fully consistent with the idea of true water, tail, "river monster." This discovery can revolutionize the science and history of the evolution of ancient animals. Researchers believe the time has come to do this.
