Spinosaurus, considered to be one of the largest carnivorous dinosaurs and has a characteristic protrusion like a sail on its back, had dense, easily sinking bones and had a body suitable for diving into water and feeding. Research groups such as the United States have announced the results of research that there is a possibility.
Spinosaurus, which also appeared in the movie "Jurassic Park" series, was a carnivorous dinosaur that lived in the Cretaceous about 100 million years ago, and there was a view that it lived underwater due to the characteristics of fossils.
Research groups such as the Field Museum of Natural History in the United States have examined the bone densities of approximately 300 species of animals that lived in water and on land, including extinct ones, and published the results in the British scientific journal Nature.
According to it, the bones of Spinosaurus are dense and easy to sink, similar to the characteristics of animals such as penguins and crocodiles that often live underwater.
Animals that lived on land, such as Tyrannosaurus, tend to have relatively low bone density, and the research group says that Spinosaurus is likely to have dived into the water and hunted, preying on fish and the like. increase.
Regarding this, Makoto Manabe, Deputy Director of the National Museum of Nature and Science, said, "This is an important report that may reinforce Spinosaurus's theory of underwater life, but there are various counterarguments. It is a popular dinosaur, so I would like to expect further discussion." I'm talking to you.
